https://devzone.nordicsemi.com/f/nordic-q-a/58123/problems-on-i2c-with-ble-uart-irregular-bounce-of-i2c-dataHi. I&#39;m using nRF52832 with MPU9250 IMU sensor to gather accelerometer, gyroscope data for mobility. MPU9250 sensor is connected to nRF52832 via I2C line. When I use MPU9250 only, all the data is good. No bounce.

What happens if you don&#39;t start the advertising (<em>ble_advertising_start()</em>)? Does the problem still appear?</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
