I found out something mysterious. And may some of you and someone knows this phenomenon and can explain it or has a solution for it:
After change Mav_2_config to Serial 4/5 i get ther error “accel #0 fail timeout”
I am using following Setup:
- Cube Black (Pixhawk 2.1) with PX4 1.12.3
- 3DRadio on Telem1 for Telemetry
- Mav2Hott on Telem2 for Telemetry to RC
and the plan is to connect a telemetry connection to GPS2 (Serial 4/5). It works, but then i can’t arm anymore, because “accel #0 fail timeout”.
