A place users can post their projects. If you have a small project and would like your own dedicated place to post and have others chat about it then this is your spot.

#83215 I reverted back to 2.4.2 and I still cannot get the NodeMCU board to see the BME280. I'll try going back even further and perhaps try rolling back the BME drivers in case they were also updated.

#83216 I would try a I2C scanner sketch. It would eliminate one unknown, the BME280 library. If you can't see it with a scanner, then you have lower level issues.

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.
