I have in issue with the blue cube. Now I don’t know if it’s an hardware issue or something else since this is the only board I have tested.
About 50% of the times the cube stucked in flashing orange light when power is attached and won’t initialize.
I can’t put my hand on what could be the problem since it’s could happen when the vehicle moves and when it’s not.
The firmware by the way is ArduSub latest.
