+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.

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

+xYou 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. Thank you Tim.

+xI can't commit to a time schedule, sorry. I need to re-engineer part of the Bluetooth stack before it will be practical, and that could be weeks or months. 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.

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?
