Re: bme280 possibly failed... how to test
Posted: Fri Jul 19, 2019 9:33 amThat's a good suggestion. I did try out a Sonoff WiFi bridge recently and updated to 2.5.2 to get that one working. I'll go back to 2.4.2 and see if that helps.

Do you have some LEDs that you can connect from Vcc to SDA and SCL? See if they flash. It would be what I would do rather than pull out a scope.
