Hi,

Your modified code in "common.c" and "accel.c" look ok. Could you please let us know what the issues are. Could you please show us the output of "scan.py" and "ble_NUS.py"?

Thanks.

I can connect APP3.0 via BLE on PC.
Thank you for your support.

By the way, is it possible to return USB connection from BLE?
If possible, could you provide us the correct method?

I tried to the following method, but error happened.

1)C code change from BLE to USB.(Use original source code of "accel.c" and "common.c")

Hi,

You can try to double click "update_bootloader.bat" in the folder C:\COINES\v2.8.8\firmware\app3.0\bootloader_update. This will make APP3.0 board go back to factory default settings. Please let me know how it goes.

Thanks.
