+x+x+x+xNo, 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. 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
I'm not sure I understood you correctly, you only connected ONE bluetooth device to the Funke radio AND to the Dynon autopilot? How did you do that? Yes, i have on one IRXON Trig radio and Dynon AP... Just use the same RS232 wire for both... This workaround is called multidrop. This only works if there is ONE transmitter and multiple receivers. The recipients all receive the same data packets and discard those they do not understand. As soon as the receivers also have to react, this concept with RS232 fails. Devices transmitting at the same time lead to collisions. The transmission becomes unreadable. I believe SD has only sent over BLE so far. Some devices, e.g. the Becker AR6201 also need to send data to SD, and then multidrop will fail. I assume that each controlled device has to use its own BLE. Maybe Tim can say something about that?

If becker needs to send back (dont understand why, because it should only receive freq from SD, bi direction is used on glass cockpits when you control com via display and you need to see tuned freq im case that you tune freq manually on radio, this is not feature in SD, so no need to com back from radio), and if, then its still not an issue, because AP only receives, so the TX line from IRXON goes to becker and AP and TX from becker to RX irxon, there will be still only one bidirectional device...

Becker can only control both frequencies in one command, so you need to know which frequency is tuned in the other channel. You have to read the status of the device constantly. And that creates traffic to SD. 2 Becker radios on one BLE device definitely doesn't work. But I think Tim should say something about this...whether he allows such a configuration or not.

Our new 4.0.1 version allows the TX part of the Bluetooth configuration to be connected to both a radio (so frequencies can be sent) and autopilot (so course data can be sent). In future, my goal is to allow the same Bluetooth device to also act as a GPS/traffic receiver through the RX part, but that cannot currently be done, you need two Bluetooth devices in this case.
As Michael says, as soon as a device needs bidirectional communication - as the Becker radios do - this concept will not work.

+x+x+x+xAll,
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!
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
The same module is on Amazon uk for £12, it says Vcc is 3.6V to 6.0V. 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
TTL logic level (TX, RX): 3.3V
I think the confusion stems from the fact that the bluetooth module is actually one pcb on top of another. The base pcb has a 5v to 3.3v regulator to supply power to the upper module which is 3.3v only. So 5v should work just fine.

Have received my Irxon dongle but daunted by patching into the 25pin dsub connector on my Trig radio; not least by trying to get to it as everything is rather buried behind the panel.
Was wondering if it would be possible to wire the dongle into a dsub adapter which could then be used to connect to the radio ie Trig dsub connector into adapter which then connects to radio hardware box.
One like this wired correctly? https://www.amazon.co.uk/CY-Adapter-Parallel-Extension-Connector/dp/B0CWH7NQMY?th=1

It looks like all 25 pins are routed 1:1 "around the 90 degree corner". But I can't read that anywhere. It will probably work.

+xOr maybe more user and installation friendly is IRXON BT578 v3 or BT580, they work with Apple and Android well... Hi, I purchase that device from AliExpress. Unfortunately, it doesn‘t react to AT+MODE=BLE in order to switch the Bluetooth mode to Low Energy. The connection to my tester-app terminal works because I get OK in reply to a sole AT command. Any idea how to fix this problem? I need LE because the iPad will not connect to BT. Thanks and best regards, Wolfram

I'm not sure I understood you correctly, you only connected ONE bluetooth device to the Funke radio AND to the Dynon autopilot? How did you do that? Yes with Y cable. It works perfectly with Android, but with Iphone it only works to control one device
