Any news on this?

Hello Tim,
Maybe not a lot of people are mentioning this, but i think a lot of people would like to have this. We would like the options for the G5 the gamin auto pilot and the AT-1 together with the setup for the radio.

That exactly what i think too, and what i want to get...
Then you dont have to feed g5 or any AP with gps like garmin aera...

Would you expect SkyDemon to send GPRMB sentences only, or also synthesize GPRMC sentences and similar?

GPRMC, GPRMB, GPGGA, and one of GPBOD or GPAPB
By Tim Dawson - 5/28/2024 9:09:41 AM

That makes life harder, because usually we do not even have access to raw GPS sentences, so we would need to be creating those messages with synthesized information. Please email us through the contact form on our website, and ask for it to be forwarded to me, and we can continue this discussion offline. In due course I'll be able to make a beta available to you for testing purposes.

From what I've heard, people drive their Skyview autopilot from the Skyview itself, having transferred the SkyDemon route on to it.

I do not know that the Skyview autopilot can be disconnected from the Skyview and given commands by other software, but if it can, and it accepts those commands via RS232, then our solution might work.

Yes, you send the SD route to SV via wifi connection from SV then, once on SV, it can drive autopilot etc. but what I'm referring to is effectively using SD as a navigation source into SV so any changes made in SD would be reflected real-time in SV. Perhaps my confusion but that is what I understood the BT connectivity would enable?


Hi, SV is intended to use internal SV maps to drive AP, i have to look into manuals if it is possible to drive SV AP over RS232.
This what will be in SD is meant to drive older Dynon APs, as well as Garmin AP with G5, stand-alone autopilots. There it will work real-time.

Hi,
I tested it today with this equipment:
VAN's RV6 experimental, iPad mini 6, Skydemon 4.0.0.397, Blutooth->RS232 Adapter Bt578v3, TRIO Autopilot.
It works perfectly !! :-)

By mbechc - 8/21/2024 7:31:05 AM

I would like to sign up as beta tester if needed.

I have the Skyview Radio panel which is useless in Denmark with all our small grass-strips (Half the flying time is spend rotating for new freq) - I would simply be overjoyed to have Skydemon able to transmit frequencies to the remote radio unit and put tape over the Dynon radio panel. You just smashed it with this feature....

Secondly I transmit routes from Skydemon to FPL inside Skyview, but having the servoes run by Skydemon is also extremely valuable. The last stretch were we get landing information and select the landing pattern in Skydemon can now be flown by autopilot controlled by Skydemon as I seldom have time to transmit FLP to Skyview and select the right leg inside FPL menu in Skyview - this is also a killer feature.

Wow just wow
I have bought the serial adaptor and are ready to test
By Tim Dawson - 8/21/2024 9:17:31 AM

No need for more beta testing of these features as they went live earlier this week in our new version. SkyDemon 4 is out now and it includes sending of frequencies to radios, and course data to autopilots.

Hi @Tim and everyone,

I'm working on building a Bluetooth to CAN bus interface and transforming the message, which isn't too challenging. However, as an iPhone user, I'm running into difficulties connecting to SkyDemon from a Bluetooth-enabled microcontroller.

My main question is: When SkyDemon starts scanning for devices, what exactly is it looking for? Is it expecting an RFCOMM or SPP connection via Classic Bluetooth, assumingly as a server? Or is it scanning for a specific GATT using BLE? It would be really helpful if someone familiar with the scanning and connection code in SkyDemon could clarify this.

Additionally, I've ordered one of the standalone converters that were mentioned earlier. Once it arrives, what configuration is necessary for it to connect properly?

Thanks in advance for any guidance!
By Tim Dawson - 8/23/2024 9:30:52 AM

SkyDemon uses Bluetooth low energy (BLE). There's no pairing process, there's no SPP, it requires pretty much no configuration, so it's very easy.

BLE to RS232 has a defined service and characteristic UUID (one for each) which you should be able to find online.

Hi all

Can anyone confirm it is working on android devices?

I've tried on 3 different devices with different BLE versions, and SD were not able to discover any of my BLE devices.

You can not find a BLE-Device with native IOS. You must find and add it from Skydemon. (read Manual)

The IOS APP "Lightblue" can show BLE-Devices nearby (like Apple Airtags)

SkyDemon works great with BLE devices on iOS and Android, it has been tested extensively on both using the BT578 but others should work the same.

We don't have a list of radios that support the Garmin protocol that we use. Trig are definitely included.

Since the Bluetooth to RS232 converter is accessed via SkyDemon, does that mean it is still possible to pair other devices with the Bluetooth function of an iPad? I'm thinking of something like sending the route to an autopilot (connected through SkyDemon) and having the iPad connected to a headset with Bluetooth connectivity (for SkyDemon audio) using the normal Bluetooth function.

vikino - 8/4/2023 7:57:32 PM
Well...

I have tested theese BT-RS232 modules a lot by my self, it works great with Dynon EFIS-D100 + AP74 autopilot and Trig TY96 COM radio, also without any issue with KRT2 COM radio. You just need to "match" baudrate to 4800 or 9600bps, that should do in this case SkyDemon, afterwards it works like a charm, no drop outs with Samsung tablets or my phone Samsung S23 Ultra.
And all another BT to RS232 work in the same way like this one, all are in the phone as bluetooth com port, all this seems to me much easier and more stable than 3rd party devices which are connected over wifi. Not talking about that you kill your internal data sim when connected to wifi of "ADAHRS" and so on...

This will just work perfectly.

Btw., with this, you can go to compleete system, because when you connect to this serial converter also Garrecht TRX1500 (for example), you can use SkyDemon as traffic display - by using GTX TIS protocol over that single BT-RS232 module.
In the same way i have it with Garmin AERA 760, but planning a route is terrible on that device, but Garmin has built in RS232...



Tim Dawson - 7/5/2023 9:13:53 AM
No, not until there is a device with widespread uptake in the community that we can actually develop with. We can't just "support Bluetooth" without a known device to develop and test with.

I have now flown a bit with both radio and autopilot connected to each blue tooth unit, and it works perfectly. My experience is that it is easy to accidentally press a new radio frequency if the air is bumpy, so I have chosen that they end up in standby mode, therefore a request for a button to switch standby/active in skydemon, also a numeric keyboard in the radio tab would be good. the auto pilot has everything I could wish for
By moefly - 9/22/2024 4:55:46 PM

All,

I was very excited when I read about the feature in the Skydemon release note, went right into ordering parts and figured I share the experience here.
Top 1 priority for me was to get the radio (f.u.n.k.e. ATR833-II) connected. So I designed a 3d case that perfectly fits on top of the original Sub-D connector housing and uses the existing screw holes (only needed slightly longer screws). Once mounted, it sits below the connector at the back of the radio and doesn't block anything else / basically uses the same space.
I decided to use a HM-18 BLE to serial module. It is very power efficient and therefore I could easily use the 5V the radio provides on the Sub-D connector. The HM-18 is outputting TTL serial, hence I added a MAX3232 converter to provide the proper RS232 levels the radio expects.

Put everything together and it worked right away. For me it's almost a killer feature in Skydemon as it makes my life so much more simple during flight.
A big thx to Tim and his team for adding this feature!

In case anyone is interested in the 3d model and a more detailed info on connection and parts I used, you can find all of that here on printables:

Hi Tim,

What feature can we expect regarding the traffic?
For example : To send the traffic received from Safesky in SkyDemon to a Dynon Skyview (with a Bluetooth module connected)?

Thanks.
By Tim Dawson - 9/26/2024 9:51:37 AM

You can connect a FLARM traffic receiver to SkyDemon via Bluetooth so that the traffic it receives is displayed in SkyDemon. That's the only relationship between traffic and Bluetooth.

Hi all

If anybody is connecting the BT receiver to the TruTrak 385 autopilot, I would be interested to hear. It's currently getting GPS feed from an old and useless AvMap Geo Pilot II+ that I would like to replace
It seems that it may need engineer from avionics specialist but I would like to do it myself (flying non certified) because from what I see on Skydemon manual, it seems pretty simple. Pins connecting to Ground on both side, Rx Pin on autopilot connecting to Tx on BT receiver.
On Irxon BT578, pin 5 is Gd and 3 is Tx, and it can't be rewired. So it probably means to create a RS232 cable if rewired is needed on autopilot RS232. It may be better anyway to avoid plugging the BT receiver directly to the avionics (thinking that it may be a pain if anything has to be done on the receiver if not easily accessible). Any recommandation on the type of wire/cable to be used if needed (shield?)


thanks

Hi moefly,

according to HM-18 datasheet the power supply voltage is from 1.9V to 3.7V.
The ATR833 has 5V output.
Do you use a voltage converter or do you just run out of specs?

Can anyone confirm if the available protocols work with a Becker AR6201, and they have it working.

No, it will not work by default.

First, some words about TTL and V24.
The mentioned working transceivers (Garmin GTR 225, f.u.n.k.e. ATR833-II, Trig TY 91/96) have a RS-232 interface with V24 voltage level.
This means serial transmission with logical low at -12V and high at +12 V (nearly...).
The cheap BT-Modules (which work like a charm with the iPad) have TTL voltage level. (low at 0 V , high at + 5V).
To connect it to your RS-232 transceiver you need a voltage level converter.

Something like this:


Now to Becker.

Can anyone confirm if the available protocols work with a Becker AR6201, and they have it working.

No, it will not work by default.

First, some words about TTL and V24.
The mentioned working transceivers (Garmin GTR 225, f.u.n.k.e. ATR833-II, Trig TY 91/96) have a RS-232 interface with V24 voltage level.
This means serial transmission with logical low at -12V and high at +12 V (nearly...).
The cheap BT-Modules (which work like a charm with the iPad) have TTL voltage level. (low at 0 V , high at + 5V).
To connect it to your RS-232 transceiver you need a voltage level converter.

Something like this:


Now to Becker.
The AR6201 has an RS-422 interface. RS-422 is electrically different to RS-232 (4 lines, current driven).

As I mentioned before, Becker has its own protocol, nothing like NMEA (ASCII) PGRMC sets. You need to translate the output/input into Becker language. A separate controller with translation software is required.
Even if you can communicate with the AR6201 via a converter (RS-232 <-> RS-422), the device does not understand the commands.
I'm working on it.

Please confirm that you are interested in a solution. The more interested parties, the better.

Becker does offer its own rs232 to rs 422 converter (available for 180£ from Mendelsson…) I don’t know if this includes a “translator” inside. There are a least 2 pilots in my club who would be interested in a solution but we are both useless at programing😇

Well, it depends ;-))
If Skydemon could add this type of device in his software it would be the smartest solution. Tim, are you listening?
If not, there is a piece of hardware needed. At one end the BT-Dongle, in between a small microcontroller with the translator and at the other end a RS-422 interface. This unit could be shrinked down to the size of a matchbox.

Hello I have connected 1 bluetooth device to Funke radio and Dynon autopilot. It works great with Android but doesn't work with iPhone. With iphone you have to choose radio or Ap. Did we miss something or does it not work to control both with the iPhone. Is there anything that solves this? or should I mount 2 bluetooth units one yill radio and the other for AP

SkyDemon uses Bluetooth low energy (BLE). There's no pairing process, there's no SPP, it requires pretty much no configuration, so it's very easy.

BLE to RS232 has a defined service and characteristic UUID (one for each) which you should be able to find online.

@Tim there doesn't seem to be a defined BLE serial UUID, only for classic BT. Could you point me to the UUID serial spec you are using? 

We can see our device in SkyDemon and it connects but then complains about the service. 

Many thanks

We are advertising the service UUID 0xFFE0 (0000FFE0-0000-1000-8000-00805F9B34FB) and SkyDemon can see the device, it appears in the list when we go to Connectivity -> Add Bluetooth Device. When we try and connect, we can see SkyDemon connecting to the device and performing some negotiation steps, but it quickly fails with the error message “No serial port service found”. We are assuming that this is because it can’t find the characteristics it’s expecting, those with suitable read/write/notify permissions. Can you give us some insight into what SkyDemon is looking for when it tries to validate that the BLE device is indeed providing a “serial port service” (we’re using BLE so it's not the Bluetooth Classic SPP protocol we’re trying to provide)?

It’s our understanding that the client device would normally look for write and notify permissions on one or more of the characteristics. We can connect other software (the python ble-serial module for example) to our device and communicate with it as if it were a serial port adapter. Our device is currently providing a characteristic with UUID 0xFFE1 (0000ffe1-0000-1000-8000-00805f9b34fb) with WRITE, WRITE_WITHOUT_RESPONSE and NOFIFY permissions.

Once we connect to the device the first thing we do is list its services, and look for the one matching FFE0. If we don't find it, that's when the connection will be aborted with "No serial port service found.".

All,

I was very excited when I read about the feature in the Skydemon release note, went right into ordering parts and figured I share the experience here.
Top 1 priority for me was to get the radio (f.u.n.k.e. ATR833-II) connected. So I designed a 3d case that perfectly fits on top of the original Sub-D connector housing and uses the existing screw holes (only needed slightly longer screws). Once mounted, it sits below the connector at the back of the radio and doesn't block anything else / basically uses the same space.
I decided to use a HM-18 BLE to serial module. It is very power efficient and therefore I could easily use the 5V the radio provides on the Sub-D connector. The HM-18 is outputting TTL serial, hence I added a MAX3232 converter to provide the proper RS232 levels the radio expects.

Put everything together and it worked right away. For me it's almost a killer feature in Skydemon as it makes my life so much more simple during flight.
A big thx to Tim and his team for adding this feature!

In case anyone is interested in the 3d model and a more detailed info on connection and parts I used, you can find all of that here on printables:
https://www.printables.com/model/1015550-funke-atr833-ble-rs232-case

Hi moefly,

according to HM-18 datasheet the power supply voltage is from 1.9V to 3.7V.
The ATR833 has 5V output.
Do you use a voltage converter or do you just run out of specs?

Regards,
Tobi

You're right. Thanks for the response.
Even on DSD Tech homepage you'll find:
    Work voltage(VCC): 3.6V to 6V
    TTL logic level (TX, RX): 3.3V
But on the linked datasheet you'll read:
    Power: +1.9~3.7 VDC 50mA
I'll just try it.

Thanks,
Tobi

Hello, 

first off, thank you for including such a nice feature! Now to my problem Smile... Since several people reported that the DSD TECH bluetooth adapters work also fine, I ordered them as well. And in my opinion I did almost everything to get it working, but is is not. 

My setup:
DSD Tech HM-10
Trig TY 96 (to test the feature in the aircraft)
Trig TY 91 (to test the feature at the bench)

What is done and working:
- HM-10 connect succesfully to skydemon
- wiring done correctly to serial inferface of the radios
- I also tested the setup using my computer and a serial monitor (e.g. for clicking on the Bournemouth Approach frequency 119,480 in Skydemon I receive the following message $PGRMC01GC014< on my serial monitor)

What is not working:
When I do this with my Trig radios.

What I think what could be the problem:
The DSD Tech adapters can not handle a power supply of 5V from a different source than ground and rx signals are coming from. My usb-serial converter which I use on my computer provides vcc, ground, rx, tx from one source which is my computer. For the Trig radios thats a different story since they do not offer 5V output. So you have to get the 5V from another souce in your aircraft and that does not work. Maybe I'm completley wrong..
For the Funke ATR833 radio this problem does not exsist, since it offers a 5V output on pin 24 and therefore all signals that go to the bluetooth adapter come from one single source which is the ATR833. So far im guessing that only the IRXON adapter works with Trig radios, since it has a internal battery and can accept powering from external source.

My questions would be:
- Did someone succesfully connected a DSD TECH bluetooth adapter with a Trig radio? 
- Did someone sucessfully connected a DSD TECH bluetooth adapter that is powered externally to any of the other features Skydemon    offers using this functionality (auto pilot commands, traffic / gps information)?
- Is $PGRMC01GC014< the right received message to Bournemouth Approach frequency of 119,480?

Any feedback is much appreciated. Thank you!

Rob

This is also true for HM-10 and probably most of the adapters.

Hi all

If anybody is connecting the BT receiver to the TruTrak 385 autopilot, I would be interested to hear. It's currently getting GPS feed from an old and useless AvMap Geo Pilot II+ that I would like to replace
It seems that it may need engineer from avionics specialist but I would like to do it myself (flying non certified) because from what I see on Skydemon manual, it seems pretty simple. Pins connecting to Ground on both side, Rx Pin on autopilot connecting to Tx on BT receiver.
On Irxon BT578, pin 5 is Gd and 3 is Tx, and it can't be rewired. So it probably means to create a RS232 cable if rewired is needed on autopilot RS232. It may be better anyway to avoid plugging the BT receiver directly to the avionics (thinking that it may be a pain if anything has to be done on the receiver if not easily accessible). Any recommandation on the type of wire/cable to be used if needed (shield?)


thanks 

You can swap rx/tx with M/F switch on irxon, but off course is better to solder simple wiring...

Can anyone confirm if the available protocols work with a Becker AR6201, and they have it working.

No, it will not work by default.

First, some words about TTL and V24.
The mentioned working transceivers (Garmin GTR 225, f.u.n.k.e. ATR833-II, Trig TY 91/96) have a RS-232 interface with V24 voltage level.
This means serial transmission with logical low at -12V and high at +12 V (nearly...).
The cheap BT-Modules (which work like a charm with the iPad) have TTL voltage level. (low at 0 V , high at + 5V).
To connect it to your RS-232 transceiver you need a voltage level converter.

Something like this:


Now to Becker.
The AR6201 has an RS-422 interface. RS-422 is electrically different to RS-232 (4 lines, current driven).
But it isn't the main problem, there are many converter from TTL to RS-422 available.


The challenge is the implementation of a translator from NMEA (ASCII) PGRMC sentences to the in-house Becker protocol.
I found an Open Source solution used in the LK8000:


There should be any information needed for such a piece of software...
I can't wait to try it out when I can have an AR6201 outside of the plane.

I would be happy to help. I have SD running on iPad Mini 4 and would want to connect to Dynon Skyview touch. Im reasonably competent but would need some guidance re hardware and connection.
By Tim Dawson - 6/21/2024 8:45:54 AM

Thanks, but we already support connections to Dynon Skyviews. Unless I am confused about that products in question?
By Skyboy999 - 6/22/2024 7:30:09 AM

Present support is to send flight plan from SD to SV via SV wifi. This thread is about real time guidance from SD to drive SV autopilot which, I understood, requires the discussed BT connection etc. Or have I misunderstood? If capability already exists to do this then fantastic- please tell me how!
By Tim Dawson - 6/24/2024 10:15:34 AM

From what I've heard, people drive their Skyview autopilot from the Skyview itself, having transferred the SkyDemon route on to it.

I do not know that the Skyview autopilot can be disconnected from the Skyview and given commands by other software, but if it can, and it accepts those commands via RS232, then our solution might work.

Yes, you send the SD route to SV via wifi connection from SV then, once on SV, it can drive autopilot etc. but what I'm referring to is effectively using SD as a navigation source into SV so any changes made in SD would be reflected real-time in SV. Perhaps my confusion but that is what I understood the BT connectivity would enable?
By Tim Dawson - 6/25/2024 9:07:25 AM

I'm afraid we have exceeded my knowledge of how the Skyview can connect to other avionics, sorry. Our forthcoming Bluetooth connectivity will allow SkyDemon to be connected to autopilots that accept GPRMB sentences over RS232 to set the current heading etc.
By vikino - 6/1/2023 5:02:31 AM

Hi all, there has been a lot of discussions about this, but never resulted in any way.
Is it possible, somehow, to get out from SkyDemon over bluetooth to RS232 converter some data?
From my current Aera 760 i have over serial port connected autopilot and Trig radio so Aera can feed AP with planned track and when i click on airfields com freq it sets stand by freq. But, it is Garmin and their weird navigation point stupid names, airfields without names and so on...

This will be nice to have on SkyDemon, are there some possibilities?

Hi. I cannot get my iPad (mini 5 running version 17.5.1 and SD version 4.0.0.397) to connect to the IRXON Version 3 Bluetooth to beam frequencies to my transceiver (Funke ATR833). However, this works perfectly using my iPhone (also running Sky Demon 4.0.0.397) 

On my iPad I go into CONNECTIVITY - ADD BLUETOOTH DEVICE - then all I get is "SkyDemon for iPad Not Authorized" as per below - any thoughts on what I am doing wrong. As I stated above it works perfectly with my iPhone?




By Tim Dawson - 10/29/2024 10:16:30 AM

You would have been asked, when first trying to use Bluetooth with SkyDemon, whether to give SkyDemon permission to use Bluetooth. It appears you said no (or somebody did) so now SkyDemon does not have permission. You can fix this in the Settings app, probably under Privacy or Bluetooth, where you control which apps are allowed to use Bluetooth.
By Gaznel - 10/30/2024 6:42:03 AM

Thanks Tim - sure enough going into iPad - Settings - Privacy & Security - Bluetooth - in there, Sky Demon was showing with toggle off for Blue Tooth permission. I have toggled this to green to now give permission. Looking forward to seeing it now work when I next go to airfield 👍🏼
By Tim Dawson - 5/8/2024 10:38:34 AM

Ok, we have started work on getting NMEA autopilot sentences out of SkyDemon, and we would like to explore the Bluetooth option.

vikino, are you still willing to test this? What's your current recommendation for a Bluetooth-to-RS232 device? We will need to purchase one/some for testing in our office, and figure out a good way of testing that the data really is getting to the RS232 feed from the device.

Hello, off course i want to, also with AP if it is possible to send COM freq to radio by clicking of freq in SD.
Best what i hafe found, tested and best for this usage is IRXON BT578 v3, it can do BT Com (SPP profile) and also BLE, so it works with Apple and Android
By Tim Dawson - 5/8/2024 1:26:00 PM

Is either of these the correct item?

By vikino - 5/8/2024 1:44:14 PM


The first one
By Tim Dawson - 5/8/2024 2:25:43 PM

Ok, I've ordered one, it should turn up in the next two weeks.

Let me know when you have app prepared for testing, at best for Android, apk or whatever i can install. I already made RS232 connector in my plane, so im ready plug and play, or plug and fly Smile
By Tim Dawson - 5/9/2024 8:58:04 AM

It's likely to be an iOS development first, but I'll post here when we have something working.

Okay, i have also some apple device, so no problem with testing on apple first...

If it helps I can also offer tests with a KRT2 radio which is available via an BLE-compatible device (esp32 based).

I have hard wired TRIG TY96, TY91, some Garmin radios, its no problem to test them all Smile
Afterwards we can try to connect Garrecht TRX-1500 air traffic over the same Bluetooth, because its also working in my plane over the same RS232 like autopilot, and its already supported in SD, only newer version AT-1, but sentences are the same.

Those features will be HUGE improvement in SD for all pilots Smile
