    BMX160 magnetometer indirect read

    I am trying to perform the self-test for the bmx160's magnetometer but I haven't been able to find any information on how to use the indirect read to get the test results. Here are the steps I am taking to do the test:

    1. Set mag_manual_en bit

    2. Put mag in sleep mode

    3. Indirectly set self-test bit (Write 0x01 to MAG_IF[3], then write 0x4C to MAG_IF[2])

    4. Set indirect read address to 0x42 for Self-Test-X result ( Write 0x42 to MAG_IF[1])

    After this I dont know how to actually access the data that is being indirectly read from MAG_IF.

    Does it go to the DATA register?

    Hi Rkreinin,

    You can refer to a previous post about using the BMX160 here.  In addition, you may use the BMM150 self-test functions to perform the self-test prior to data streaming.

    Using the auxilliary interface directly would be more complex without a driver.
