Hello,

Can you send me the whole project so that I can check it from here ? In addition what do you mean by saying ''two examples are the same''?

Thanks.

Best Regards,

Thanks, actually, the two examples are the same, my nRF52840 used pin(0,29) for SCL and pin(0,28) for SDA.

Hello,

I think there may be conflict in pin assignment when two examples ( i2c_mpu9250 and ble_app_uart) work together. Could you please share what are the pins used for i2C?

Thanks.
