Followed this https://github.com/BoschSensortec/BMI160_driver/wiki/How-to-use-an-auxiliary-sensor-or-magnetometer-... post and connected BMX160 to nrf52 DK. TWI initialization, BMI160 initialization, accelerometer and gyroscope set config is success. After that x,y,z readings are zero from both accelerometer and gyroscope. I think user_i2c_write and user_i2c_read functions has error. Please go through the code and suggest any changes.
main.c and output is attached.
If it's only a question of Sensortec, they have their own dedicated board, which is the best place to get feedback. Can you try the question there?
If it's for XDK I saw you already posted there too, thanks!
