I tried V5+ flight controller ,

  1. set MAV_1_CONFIG to TELEM2,
  2. reboot
  3. the SER_TEL2_BAUD show up
  4. change SER_TEL2_BAUD to 57600
  5. TELEM2 can connect to QGC just like TELEM1

For V6X

  1. set MAV_1_CONFIG to TELEM2,
  2. reboot
  3. the SER_TEL2_BAUD not show up

I confirm the same behaivor on the PX4 build 1.14, while on version 1.13.2 thing work ok.

I tried to update them manually using MAVLink Console in QGC, using param set/param save but no success.

The consequence is I cannot connect to companion computer using TELEM2 port. I attach a zip with both parameters extracted from 2 devices. Once i downgraded the second device to 1.13.2 it started to work.
