ESP32 boot loop when calling bme.begin()

chikiball commented 2 years ago

First off, did you read the manual? Did it answer your question? Yes, No Second, did you look at the examples? Did they answer your question? Yes, No No, alright, please describe the problem below.

I am using ESP32 Dev Kit. All wirings are confirmed. When calling bme.begin(), ESP32 goes into panic mode and keep on rebooting.

Expected behavior

Should not reboot

Actual behavior

Goes into boot loop

Steps to reporduce the behavior

call bme.begin() in the setup() function.

Solution:

BME280.cpp InitializeFilter() should be a void function instead of expecting to return bool. BME280.cpp WriteSettings() should be a void function instead of expecting to return bool.

Downloaded the library from platformIO library, I guess it is not the latest update.

The same problem also affects ESP8266 with board versions 3.0.x (with 2.7.4, bme.begin() does not crash). Changing these functions to void type seems to fix the problem.

The issue was fixed in branch master since Feb 11th, but an updated version wasn't published on platform.io, so adding finitespace/BME280 on platformio.ini results in downloading a buggy version. This explains why this only happens on platformio and not on arduino or by downloading from github.

Solution: Publish an updated version on platform.io.

Workaround: specify the git URL on platformio.ini:
