Regenfass - Debugging

On development you often point to bugs and errors. To make it easier for us to find and fix them, we have integrated a debug mode into the Regenfass. This mode can be activated in the config file. The debug mode is only active if the Regenfass is started with the parameter --debug or -d. The debug mode is deactivated by default.

[env:heltec_wifi_lora_32_V2]
platform = espressif32
board = heltec_wifi_lora_32_V2
framework = arduino
lib_deps = heltec/ESP32_LoRaWAN@^1.1.1
