Hi, I use a STM32 (Lora-e5 from seeedstudio) and a BME680. I use the standard code and it runs without error until about 70 minutes. Then the hole system stops. I can't find any error (no HardFault, no Reset error). As you can see in the 3 runs, the system stops at about 70 minutes Run 1:

Some code files are in the attachment. Johannes
