@sash-sc upgrade MySensors to 2.3.2 or downgrade the esp board definition. More info: https://github.com/mysensors/MySensors/releases/tag/2.3.2

Great work @mcchots, thanks for reporting back

Hello, there is a possibility to check the connection. I will test with receive command from controller to the gateway and write a timeout to reset the ESP with ESP.reset or ESP.restart. regards ThomasD
