Hi, Thanks for the reply. we are working in this. As you suggested, we tried with NDOF mode. so after on power on reset i got some data in the heading field, but it is not same as the heading data before software reset. so there could be some issues like where i need to store the calibration profile and when it needs to be applied in sensor. Here is the operation we need., 1. i will make the sensor in suspend mode, 2. after a period, i will give soft reset,and make the sensor into config mode 3. and put the sensor in NDOF operation mode, collect the data 4. again do soft reset and put the sensor in suspend mode this is what our requirement. we have below questions now., 1. When we need to check the calibration status register and what are all the things to be verified in getting 3 (Acclero,gyro and magneto alone or i should get system also i,e i should get 0xFF in that calibration status register?) 2. when i need to check the calibration status and store the calibration profile ? in Suspend mode or in after putting into NDOF mode (Bcoz in data sheet,they mentioned calibration profile should be taken after calibration and in config mode) 3. When i need to write this calibration profile into the sensor as per my requirement. So please provide us more details to use the solution provided by you. Thanks & Regards, Uma Maheswari.G
