Hi,
I am facing the issue of MAV> Link 1 down
I have connected Pixhawk2.4.8 to RPI4 following the guidelines at https://ardupilot.org/dev/docs/raspberry-pi-via-mavlink.html
I have made a Serial connector from Pi4 UART pins to TELEM2 on Pixhawk2.4.8
Parameters in Mission Planner are as below
Serial2_Baud : 921600
Serila2_Protocol : 2
Serial1_Baud : 57
Serial1_Protocol : 1
Once I run the command
mavproxy.py --master=/dev/serial0 --baudrate 921600 --aircraft MyCopter
I get :-
/usr/local/bin/mavproxy.py:21: DeprecationWarning …
Connect /dev/serial0 source_system=255
no script MyCopter/mavinit.scr
Log Directory …
Telemetry Log …
Waiting for heartbeat from /dev/serial0
MAV> Link 1 down
I get the same response when I try ttyS0 instead of serial0 or change the baudrates to 57600
I do not intend to use APsync since I have to connect the Pi on WiFi to my other network. So I have to work on SSH
Any help shall be appreciated.
