After I set up the Inspire and switch on, the Go App will give the green banner message 'Safe to Fly'. But before I can check the 'Return to Home, compass and IMU settings the safe to fly message disappears and a flashing red/ steady red, Remote Controller signal weak/ No Signal banner will appear. The flashing red/ red banner will continue for between one and two minutes and then the Green 'Safe to Fly' banner will come back. I can then carry out the pre-flight checks, start the motors and usually have no problems flying. I have contacted DJI but only get the What's the firmware? Try formatting the SD card, Do a compass and IMU calibration. You will have to send the aircraft in to DJI. Has anyone had similar issues or any idea what the problem may be? I have had this problem from when I received this replacement Inspire at the beginning of May 2016. Initially it only occurred occasionally but now seems to do it at every start up.
