    BME680 sporadically stops working

    Hi,

     

    I'm running a BME680 breakout via I2C connected to a RasPi Zero for about a month.   Since two days the sensor stops working and I can't even see it with i2cdetect.  After a power cycle it continues to work, but only for a day or two.  Is there any chance I could debug this or is the board or sensor just broken?  There is no mechanical stress, it's indoor use and not moved, just sits there...

    The respective error in Python is

    Jan 23 13:59:26 piz1 python3[5137]: return self._i2c.read_byte_data(self.i2c_addr, register)
    Jan 23 13:59:26 piz1 python3[5137]: OSError: [Errno 121] Remote I/O error

    But as mentioned, "i2cdetect -y 1" does not report anything, just "--" on every address.

    Thank you very much in advance!

      Best regards,

        Karsten

    Hello km_

     

    Can you capture i2c signal using logic analyzer? 

    There is no signal? If your system is alive, at least there is some siganl master sends to BME680. 

    Thanks,
