Integration of BHI260AP with Magnetometer BMM350

[zepler]

Hi,

I'm developing an IMU system using the BHI260AP and BMM350 microchips. I've implemented Bosch's Bosch_Shuttle3_BHI260_BMM350C_BMP58x.fw firmware, but I'm encountering an error, and I've attached screenshots displaying it. Despite detecting the BHI260, there was no communication between the BHI260 and BMM350 when I attempted to capture I2C signals.

Could you provide guidance on the expected hardware configuration for this firmware? Additionally, since I'm not utilising the pressure sensor BMP58x in the design, will the firmware still function properly? Alternatively, is there firmware available that better suits our design (using only the BHI260 and BMM350 without the pressure sensor BMP58x)?

Testing setup: The BHI260AP is connected to the BMM350 via I2C, and the BHI260AP is integrated with Application Board 3.0 using SPI. The Application Board is linked to the PC for logging IMU data.

Thank you.

Hi zepler,

The firmware for BHI260AP supporting BMM350 has not yet been officially released. If you design a project and request it, you can contact with official distributor and apply for it.
By the way, which country you located?

Hi,

Thank you for the reply.

I'm from the UK. I've already obtained the firmware, Bosch_Shuttle3_BHI260_BMM350C_BMP58x.fw, from Bosch through Mouser Electronics. However, I'm encountering errors while testing my IMU design, as described in my previous comment. I was hoping you could assist me in resolving these errors.

Thank you.

Hi zepler,

If you design a project with BHI260AP and BMM350, we suggest you get in contact with one of our official distributors or sales representatives according your location to allow us to review each project on a case-by-case basis.
