Possible hang when using Adafruit_BME280::takeForcedMeasurement() #75

Closed netmaniac closed 3 years ago

netmaniac commented 4 years ago

When sensor BME280 gets disconnected or is damaged calling Adafruit_BME280::takeForcedMeasurement() can results in hanging. Reason is in loop https://github.com/adafruit/Adafruit_BME280_Library/blob/0213f84f9fe1344b99042f3a8051f489ec1ddc5a/Adafruit_BME280.cpp#L357

On ESP8266 this loop won't trigger WDT, since it is using delay.

To reproduce - connect BME280 sensor to ESP, initialize it in forced mode and read in some intervals (10s). Then disconnect sensor from I2C bus, or power it off. ESP will hang.
