The REV Robotics control hub is one of if not the most crucial part of any FGC robot so when something is wrong with it a huge problem arises. This problem happened to us during the preparation for FGC 2018.
The control hub started randomly disconnecting from the table in intervals of about 50 seconds. The hub’s built in LED was flashing purple and white which is not normal.
Also the message “Resetting AP to default” appeared on the screen of the tablet and the control hub after we connected it to a screen .
The first solution we tried was charging the battery since it was almost empty during the time the problems begun. This didn’t work. After that we asked on the FGC Discord server and Greg from REV Robotics told us that the power button was stuck which was the problem and after we got the button unstuck the control hub worked like normal.
