sps30's Issues

OSError: [Errno 121] Remote I/O error

I'm using your script, but get this error. Googling results in more similar experiences. But as far as I can see, no solution.
Strange thing is that I get an DEVICE_SERIAL which in my opinion means that i2c is correct.
Running with sudo gives same error.

$ i2cdetect -y 1
