I’ve soldered together the cable as shown in the photos and circuit diagram below and connected it between my receiver’s S.Port and my flight controller’s telem2 port, set the
SYS_COMPANION parameter to ‘Frsky Telemetry’ in QGroundControl and used my transmitter to search for sensors but I can only find the
RxBt sensors from within the receiver itself. All the sensor feeds from within the Pixhawk seem to be missing.
Really, I was just wondering if anyone could tell me if I’ve missed something like a parameter that should be set or made any other obvious errors that would make everything work as intended?
Flight Controller: Pixhawk 2 “Cube”
Firmware: PX4 v1.7.3 stable release
Transmitter: Taranis Q X7S
Transmitter Firmware: OpenTX v2.2.0
Receiver: Frsky X8R
Ground Control Software: QGroundControl v3.3.1

(Note that I’ve purposely omitted the Vcc cable on the receiver side after reading the GitHub thread related to setting this up on a Pixracer. I’ve checked with a multi-meter and the two V+ pins are electrically connected so this shouldn’t be a problem, power being supplied to the chip from the pixhawk end and to the receiver by its connection to the
RCIN port on the Pixhawk.)
