Fickle RPI : Pixhawk connection


Anyone have a suggestion why this has sometimes works, but sometimes has sluggish connection and times out (arrow) ?

Mavproxy works without issue.

I later found I could modify the__init.py__file to allow for a longer wait time and it worked. Not sure why on this drone build it is a problem but on my other ones it is not.

Hmmm I’m not sure, that is weird.

I recently toyed around with connecting the Pi to the Pixhawk with a USB connection, which seems to connect faster than UART. May be worth it to try.

I believe the device name is /dev/ttyACM0. Connect from the USB port of your Pi and connect to the micro USB of the pixhawk. Not sure if it would work with Pi Zero but I’d assume it would with a micro USB to micro USB connector.
