+# ESP8266-BME280_driver_wrapper
+
+There are several approaches for a BME280 interface class, this is one of them. I had issues with high noise.
+Imho, triggering the ESP8266 watchdog reset when the I2C setup of the BME280 device fails is a bad design, but copied often.
+
+The data sheet of the BME280 strongly recommends to use the original driver from Bosch. Therfore I gave it a try.
+Refer to: https://github.com/BoschSensortec/BME280_driver The original source code is somewhat old fashioned c language, but VS-Code/platform.io compiles it with no issues.
+
+This BME280wrapper class is just a c++ wrapper class for the original Bosch source located in the lib folder.
+The structure of this repository complies to a pattform.io project.
+
+Using an Arduino IDE you may need to move the source files of the lib folder to the main folder. I'm not using the Arduino IDE anymore. The VS-Code/platform.io IDE is much more confortable and I recommend to use it instead.
+
+To change the oversampling and filter coefficients of the BME280 device, please edit the parameters in the BME280wrapper::setup function directly. My approach was to achieve the higest precision available against lowest power consumption possible.
+
+To minimize the power consumption when battery powered you may supply the BME280 by a switchable GPIO output of the ESP8266.
+This means a hard reset for the BME280 in every deep sleep loop and may result in slightly higher noise.
+
+If you wannt to run the ESP8266 in deep sleep loop just uncomment the line "#define ESP_DEEP_SLEEP" in main.cpp.
+Please note that a functional deep sleep loop requires D8 (GPIO16) to be connectet to RST pin of the ESP8266.
