MAX86176 stop responding to any I2C communication

Product Number: MAX86176

Hi,

We are using the STM32F412 and encountering an issue where the MAX86176 stops responding to any I2C communication during FIFO readouts triggered by AFULL interrupts.

Has anyone experienced this issue before? When the sensor stops responding, we need to reset/reinitialize the communication, but so far, we haven’t found a proper fix.

Any insights or suggestions would be greatly appreciated.

Any open source driver that can be shared ?

Thanks,
