Storm 32 controller calibration

I am having problems calibrating the imu2 and camera imu on a storm 32 controller. In the OlliW BGC tool, when calibrating,values stabilise , the blue arrow doesnt appear and the option to accept values remains greyed out and cant be accessed. I have waited up to 5 mins but still cant access accept values button.
Im running v096 firmware on a aliexpress 1.31 storm 32 controller, IMU2 and camera IMU setup as on Olliw tutorial. I,m using the 1 point calibration option.
Any ideas much appreciated

Bruce – wrong forum. This is Arducopter not Storm32. Need to go to the RCGroups thread.
