I can now get the 3DR radio to work direct serial to UART, but if I add a CP2102 USB to serial to send mavlink telemetry to a minimosd, it doesnt work, actuallly both stop working, the 3DR radio and the USB data, not sure what am doing wrong, here is output of the arducopter config, am i missing something? do I need to have tty0 and tty1 because using more than one console?
TELEM1="-A tcp:192.168.1.100:14550" ##GCS Mission Planner
TELEM2="-C /dev/ttyAMA0" ## 3DR Radio to UART direct
TELEM3="-D /dev/ttyUSB0" ## MinimOSD USB->CP2102->MinimOSD
Options to pass to ArduPilot
ARDUPILOT_OPTS="$TELEM1 $TELEM2 $TELEM3"
