Hi,
I have a strange behavior with the UniversalTelegramBot Lib on a ESP32.
First of all, the code was running on a ESP8266 like a charm. Then I started to port it to my ESP32 and now I only receive a message if it is already available for the first loop run. In the loop runs afterwards I do not receive anything.
I have no clue what's wrong with the code. Does not look so complicated.
I use the following versions of the libs.
ESP board v2.0.2
UniversalTelegramBot v 1.3.0
Arduino JSON v 6.18.0
I hope you can help me on this.
