Hi everyone. My name is Tom and I'm from Germany.

I found this forum by looking for a gimbal calibration for my spark.

Thanks at all for your detailed descriptions about the calibrating process.
I have used this (DJI Spark Gimbal Calibration - Choice Technology Solutions, LLC) step by step.
After installing python and pyserial I tried to start the process by command

py comm_og_service_tool.py com7 SPARK GimbalCalib JointCoarse

but I get this message:

The Spark is switched on and the USB cable is connected. Also the COM port ist wright (COM7 in my case).
I ran the cmd prompt via admin.
Python 3.10


Can anybody tell me what's my problem?


Thanks and kind regards from Germany!
