    accelerometer and gyroscope readings (x, y, z) from BMX160 over i2c is zero

    Connected bmx160 to nordic nrf52 DK board over i2c. The x,y,z readings are zero from both accelerometer and gyroscope.

    Followed this https://github.com/BoschSensortec/BMI160_driver/wiki/How-to-use-an-auxiliary-sensor-or-magnetometer-...TWI initialization, BMI160 initialization, accelerometer and gyroscope set config is success. After that x,y,z readings are zero from both accelerometer and gyroscope.

    Hello Sijil,

    "TWI initialization, BMI160 initialization, accelerometer and gyroscope set config is success." Could you get chip id? You could capture I2C wave form to check actual I2C communication first.

    would you like to read some registers to check whether to success, like 0x02/0x03/0x41/0x41/0x42/0x43?

    If unsuccessful, probable you need to add delay function after bmi160_init or before bmi160_set_sens_conf().
