Thanks! Any idea please? Thanks for your help! That will depend on your aircraft type and what rules you operate under e,.g. certified, LAA or BMAA It’s an Experimental aircraft equipped with a Rotax 912. Easy to do some modifications under French rules. Thanks

Ok, thank you for your help. I will investigate for a converter. I think this is the only way to supply 5v to the Bluetooth module.

Or perhaps it’s possible to find a 12v Bluetooth module????

Group: Forum Members Posts: 27, Visits: 47	+x Michael Hoffmann - 8/26/2024 8:12:27 PM I have connected a DSD TECH HM-10 Bluetooth 4.0 BLE iBeacon UART module and can receive the "COM setting data" via RS232. This works really well. https://www.amazon.de/dp/B06WGZB2N4/ref=pe_27091401_487027711_TE_SCE_dp_i1 Is there a list of supported radios and their data format? Now I'm faced with the problem of wanting to control a Becker AR 6201 radio. It has an RS-422 interface. It shouldn't be a problem to convert RS232 to RS422, but the data format is unknown. Can anyone help? Thanks in advance Michael Michael, I'm trying to prevent the back of my panel looking like a PAW Classic... these wee units look far better for mounting. Can you confirm that they can output RS232 sentances for avionics? Are any resistors needed?

j Group: Forum Members Posts: 8, Visits: 0	+x vikino - 8/4/2023 7:57:32 PM Well... lets take this one: https://www.aliexpress.com/item/32967247206.html?spm=a2g0o.order_list.order_list_main.58.166c1802dSZoK5 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... +x 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

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 Edited 9/22/2024 5:00:47 PM by moefly

v Group: Forum Members Posts: 25, Visits: 51	Hello Tim, have you got any time schedule about programming ability to send AP+COM and receive traffic via single BT-RS232? Just to know if i should wire second BT device or you can get it to work in near future? Vitek
