How to use bmi088 aux mag?

[Guest]

i see the aux register in bmi088 mm feature set AN, such as 0x6b IF_CONF, it can enable aux mag,and 0x4b AUX_DEV_ID,it can read aux slave dev id.

but when i loaded the bmi088 config file later and enable 0x6b register,i can't read AUX_DEV_ID

this is my code:

send_buf[0]=BMI08x_IF_CONF_ADDR;

send_buf[1]=0x10;//enable aux

result=rt_spi_transfer(spi_dev,send_buf,RT_NULL,2);

send_buf[0]=0x80|BMI08x_AUX_DEV_ID_ADDR;

send_buf[1]=0;//read aux i2c id

result=rt_spi_transfer(spi_dev,send_buf,recv_buf,3);

Hi Guest,

BMI088 does not support aux mag. You can refer to official BMI088 data sheet and software code https://github.com/boschsensortec/BMI08x-Sensor-API
