BHI260 not working consistently across same batch of PCB's

[bsole2]

Hello,

We're trying to identify what's causing the BHI260AP to not work consistently across a batch of 30 PCB's. Some work perfectly, and some partially work sending Acceleration data, while others do not work at all, running the same firmware.

The PCB components  were ordered on or right around February 28th, 2024 by PCBWay in China who assembled the PCB's. 

Is it possible there was a batch of BHI260AP chips around this time that could have caused this? What else could possibly cause this?

Please assist as were trying to identify the issue ASAP before placing a larger order. We're planning to scale into the 1000's of units/month in near future.

Best Regards

Hi bsole2, 

Thanks your question. We don't meet the BHI260 not working issue, but I think the only difference is HW, so you should check the HW first.

Thanks
