Connection loss after takeoff

Hey guys, I’m running ArduPlane 3.7.1 on a navio2/rpi board and controlling the plane with dronekit scripts. After switching to navio from Pixhawk, immediately after takeoff we get link timeouts for 5-10 seconds then a restore, one update from APM, then this problem continues. Help please! Dronekit 2.9.0 and pymavlink 2.1.0.

from your other post

“We start the ArduPlane instance on boot after calling sudo systemctl enable arduplane. Our commands are:
TELEM1=”-A udp:"
TELEM2="-C /dev/ttyAMA0".
We then launch our dronekit script using python --connect We also tried udpin: and udpin: as TELEM1 and the zero showed improvements for two flights then the problem persisted."

the setup for telemetry over UART looks correct; how do you transfer the data? sounds like EMIs messing up telemetry data;
