BME280 | bme280 stops after the first reading

Hi @kmetz,
thanks a lot for the great instructions. Everything works beautifully over here.
The only small issue i have is, that bme280isConnected changes to false after the first reading of the BME280 sensor.
I can't seem to solve it... any pointers?

Thanks much in advance!

Ok, with the much appreciated help and feedback of @htor-j I was able to fix this, BME280 has to run in MODE_NORMAL instead of MODE_FORCED, the latter requires to re-set forced mode before each reading (it goes into sleep mode afterwards). Normal mode will update readings internally periodically and is also recommended when using filters (see datasheet).

Please use 71cc121 / v1.2.2 +.
