Telem2 not working

ArduCopter Copter 4.0

Good day ,

I am having issues getting Telemetry 2 to work on Pixhawk 4 with firmware from mission planner 4.0.7,
All works on Telemetry 1 ,

I am trying to get the FR-SKY telemetry to work on TELEM2 even tried MAV2 on the TELEM2 port and does not work .

SERIAL_PASS1,0
SERIAL_PASS2,-1
SERIAL_PASSTIMO,15
SERIAL0_BAUD,115
SERIAL0_PROTOCOL,2
SERIAL1_BAUD,57
SERIAL1_OPTIONS,0
SERIAL1_PROTOCOL,2
SERIAL2_BAUD,57
SERIAL2_OPTIONS,0
SERIAL2_PROTOCOL,10
SERIAL3_BAUD,38
SERIAL3_OPTIONS,0
SERIAL3_PROTOCOL,5
SERIAL4_BAUD,38
SERIAL4_OPTIONS,8
SERIAL4_PROTOCOL,23
SERIAL5_BAUD,57
SERIAL5_OPTIONS,0
SERIAL5_PROTOCOL,-1
SERIAL6_BAUD,115200
SERIAL6_OPTIONS,0
SERIAL6_PROTOCOL,2

So if you plug the inverter into Telem1 and set its protocol to 10, your FrSky is happy ?

Yes then it is happy and working same with the Holybro Telematry radio v3 , as soon as I used Telem2 and Plug either of the two into it it does not work.

Can you set the params for Serial 4, and use the port marked UART&I2C B instead ?
