    BMX055 magnetometer ID

    I would like to explain a question that I think I cannot explain the problem as code. I'm sorry for asking a new question.

    I am reading accelerometer and gyroscope correctly, but i can't read magnetomer. I read 0x00. 

    Is there anyone who can help with this problem? 

    Accelerometer 

    pin_set(bmx_cs1);

    pin_set(bmx_cs2);

    pin_set(bmx_cs3);

    select_bmx_acc(); //MISO=MISO1
    wait_delay(100);

    uint8_t bmx_id=0;
    pin_clear(bmx_cs1);
    wait_delay(100000);
    bmx_id=spi_read(0x00);
    wait_delay(1000);
    pin_set(bmx_cs1);
    wait_delay(100000);

    Gyro

    pin_set(bmx_cs1);

    pin_set(bmx_cs2);

    pin_set(bmx_cs3);

    select_bmx_gyro();//MISO=MISO2
    wait_delay(100);

    uint8_t bmx_gyro_id=0;
    pin_clear(bmx_cs2);
    wait_delay(100000);
    bmx_gyro_id=spi_read(0x00);
    wait_delay(1000);
    pin_set(bmx_cs2);
    wait_delay(100000);

    Magnetometer

    pin_set(bmx_cs1);

    pin_set(bmx_cs2);

    pin_set(bmx_cs3);

    select_bmx_acc(); //MISO=MISO1
    wait_delay(100);

    //wake-up first
    pin_clear(bmx_cs3);
    wait_delay(100000);
    spi_write(0x4B,0x01);
    wait_delay(1000);
    pin_set(bmx_cs3);
    wait_delay(100000);

     

    uint8_t bmx_manyetik_id=0;
    pin_clear(bmx_cs3);
    wait_delay(100000);
    bmx_manyetik_id=spi_read(0x40);
    wait_delay(1000);
    pin_set(bmx_cs3);
    wait_delay(100000);
