PreArm: Accels calibrated requires reboot

I am unable to complete the Accelerometer calibration using Mission Planner 1.3.49.
When I complete the orientation steps, I see a message in the console ‘Info: Calibration Succesful’. When I try to arm it, I see a message ‘Critical: PreArm: Accelerometers calibrated requires reboot.’ However after calibrating my Pixhawk 2.4.8, when I reconnect Mission Planner, I still receive a message: ‘PreArm: Accelerometers calibrated requires reboot’. I’m using Mission Planner on Windows 8.1. Grateful for any guidance for my problem.

You need to reboot your aicraft electronics not Mission planner :slight_smile:

Shift F4 in Mission Planner and Reboot Pixhawk should do the trick.

Thank friends. My problem solved
