1. we find a limitation in our firmware as follows: --> The EMG status must be non-active in the initial state 2. You can not change the firmware immediately. So we provide a more easy solution as follows: solution 1 : check EMG status in the beginning & auto configure the active state (assume initial EMG=in-active) refer to this demo, demo3, for reference. 3. Anyway, solution 1 can not fit all requirements. So you can modify solution 1 to solution2 as follows: solution 2 : check EMG status in the beginning & Stop running if EMG is active now 4. Another more better solution can be modified from solution 1 as follows: solution 3: check EMG status in the beginning & ask user to release EMG if it is active now. For solution 2 & solution 3, you need a MMI, so please modify solution 1 to solution 2 or 3 to fit your requirements.
