RCReceiver RSSI

The stock firmware of the included RC receiver, the FS-iA6B, does not provide any RSSI signal feedback even though the hardware is capable of it. It is possible to enable this feature by flashing a new firmware, developed by the community: https://github.com/povlhp/FlySkyRxFirmware

This GitHub has all the instructions necessary on how to access the programing interface of the RC receiver and how to flash the new firmware.

With the new firmware flashed, we now have the receiver RSSI signal output on SBUS Channel 14, which then can be read by the FMUK66 by setting the RC_RSSI_PWM_CHANNEL parameter in the PX4 firmware (can be done through QGroundControl) as shown in the figure bellow:

Enabled RC RSSI reading on SBUS Channel 14

The RSSI value is then also displayed in QGroundControl like can be seen in the figure bellow:
