Just put my 3 inch sub250 together, plugged it in and the DJI O4 successfully connected to the googles, but it shows an IMU error and does not allow me to arm. Could not find anything about IMU errors on DJI O4 online. Any ideas on how to solve this? Also, tested the same DJI o4 on pavo pico, same error.
Your camera connector could be disconnected or damaged. If the plug is loose try replugging it in and it may fix your problem. If your cable is damaged you may have to buy a new camera or mipi cable.
Tried updating and searching for any support articles, but to no avail. Called DJI and they said that it is donezo - have to send it in. Will update this thread when I get a response.
