instead of source ~/quad_ws/devel/setup.sh, use source ~/quad_ws/src/quadditch/scripts/setup.sh

if there are issues with preflight checks (e.g. accel calibration)

rm -rf ~/.ros

Make sure rosbridge is at release 0.11.10 - the next version is updated for Python3 and breaks the ROSIntegration functionality

Testing Tips

Have Pi disconnected from power supply and pixhawk at startup. I think there is an issue with transient current - when everything tries to start up at once the Pi can't get enough power. It doesn't happen all the time but turning it on second works consistently. After a few seconds (I wait for the pixhawk startup sequence to finish) power on the Pi. Give it several seconds to start booting then plug in the USB for the pixhawk connection.
