Thank you for your reply. Unfortunately, I can't use your example because it doesn't work with the Zephyr RTOS. Bosch provides a driver for this RTOS (here: https://github.com/zephyrproject-rtos/zephyr/tree/main/drivers/sensor/bmi270 ), but it doesn't support the auxiliary interface. Is Bosch planning on adding support for the auxiliary interface to this driver? I have submitted a ticket on GitHub and tagged the Bosch GitHub account responsible for making the driver here: https://github.com/zephyrproject-rtos/zephyr/issues/57252 If Bosch doesn't plan on adding support in the near future, is there another approach you would recommend for interfacing with these sensors using Zephyr? Or, would we need to drop Zephyr RTOS and use the drivers here, along with your example? https://github.com/BoschSensortec/BMI270-Sensor-API This is time-sensitive for our organization, so any help you could provide would be greatly appreciated. Thank you.

I have a custom board with a BMD-300 (nRF52832), a BMI270 (accelerometer, gyroscope) and BMM150 (magnetometer), where the BMM150 is connected via the auxiliary connections on the BMI270. From what I can tell, the only examples that exist for programming this use the Bosch drivers from https://github.com/BoschSensortec/ There also exists a Zephyr driver for both sensors, but from what I can tell there's no aux support in the BMI270 driver. My firmware is using the nRF Connect SDK and Zephyr (not the legacy nRF52 SDK). I'm able to get the BMI270 sample code running without any issues: https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/sensor/bmi270 What's the recommended approach for interfacing with the auxiliary BMM150? Should I use the Zephyr driver and read/write to i2c directly, or is that not supported by my setup? If the Zephyr driver doesn't support the auxiliary sensor, do the Bosch drivers work with a Zephyr setup? Are there any novice-friendly examples of how to accomplish this? Thank you for any help you can give.
