(Awesome work, on all your libraries! Thanks!)

In readme.md:
status = bme.setIirCoefficient(BME280::IIRC_X4);
should read
status = bme.setIirCoefficient(BME280::IIRC_4);

And thusly for all other adjustment points.

Hi,

I'm trying to access a BME 280 with an NodeMCU ESP32-S using the BME280 library.

I2C scanner finds the device, but BME280 is reporting that it can't communicate with the sensor.
Tried with the module set to both addresses (0x76 and 0x77, and also with the BME280 alone on the bus). I get the same error message when running the Basic_I2C example. The other sensor on the bus (a VL53L0X laser distance chip) is responding.

Tested the whole scenario with two BME280 modules, with the identical results.

bme.begin() is returning a -1.

Output from a small sketch returning the values for SCL and SDA, scanning the bus and the trying to initialize the BME280:

I2C port:
SCL: 22
SDA: 21

Scanning I2C Bus for clients:
Scanning...
I2C device found at address 0x29  !
I2C device found at address 0x77  !
done

bme_status: -1
Error communicating with sensor, check wiring and I2C address

Is your library specific for the Teensy so it won't work with other units, like e.g. the ESP32?

Thanks for your help!
