Blue LED does not flash once PX4 and VOXL boot up
When booting up the VOXL Flight it is expected to have the normal green solid LED and flashing blue LED.
The issue is that the blue LED does not flash once PX4 and VOXL boot up.
I would first test functionality of the voxl-flight in terms of being able to both ADB into the voxl and connect to QGC.
If all goes well with that then I'd check the px4 firmware version on the flight core side and no matter what it's at currently I'd go ahead and re-flash with our latest px4 firmware which is obtainable via our downloads.
