RSSI on T18 R8 connection to Pixhawk-4


I was wondering if the connection between “RSSI” pin on R8 that comes with a T18-Jumper and Pixhawk-4 is possible! The input that I received from the Vendor “Holybro” is listed below. Does anyone know if Pixhawk-4 supports the “RSSI” signal and if the signal is digital and available so that we can make the connection?

Firstl, this’ RSSI 'is analog. The Receiver is required to support analog RSSI signal output.

Second, ‘null’ means that the hardware is available for it but the PX4 firmware may not support this functionality yet.
