Muhammad Usman Bhinder

Hi,

i am trying to recive data from MPU9250 of SensorTag. According to http://processors.wiki.ti.com/index.php/CC2650_SensorTag_User's_Guide (figure-1 below) i need to write 2 bytes 0xFF, 0x03 to enable all the features of MPU9250 and 16G value. then there are conversion function to convert raw data to the exact value (figure-2). after doing this i am receiving some strange values and some reasonable values (figure-3). i am woundering why is it so? please guide me. the other sensors conversion function are working properly.

 

Please guide.

Best Regards

Usman

    Hello Usman,

    Have you confirmed that the displayed values are actually sent by the server or is this a display conversion issue on the client? A sniffer check would be a good first step followed by comparing the raw values on the peripheral with the MPU9250 data sheet.

    Best wishes
