Hi. I have a quadcopter with the following setup and I’m trying to get telemetry to work with the smart port on the X8R.
Transmitter: Taranis X9D plus
Flight controller: Pixhawk
I followed the guide http://ardupilot.org/copter/docs/common-frsky-telemetry.html and soldered together a custom cable with the SPC cable and TTL-RS232 converter. After all the setup, my taranis transmitter is only seeing 4 parameters:
RSSI - 100dB
A1 - 4.9V
A2 - 0.0V
From my understanding, these are the parameters that are passed by default from the receiver (not from the pixhawk). What am I doing wrong? I have tried using both SERIAL 4/5 and TELEM1 with SERIAL4_PROTOCOL and SERIAL1_PROTOCOL respectively set to 4 (not at the same time though).
Is there anything I may have missed, or is it possibly just a bad cable (how do I go about testing the cable)? Please help! Thank you!
