Connection error

Hello, we have connection problem after updating the firmware with the baudrate of 9600.

Now, we cannot connect the device (OpenIMU300RI).

We had used (1) IMU-ready-to-use program, (2) python code uploaded on github.

Could you explain how to fix it or how to do factory reset??

Send command 55 55 70 47 00 5D 5F with hex format in baudrate 57600, to check if you can get response. If there is any response with serial number, please try to upgrade the firmware again.
