1 year ago Hello bobcroft,
the issue that you pointed out is due to a problem with the ArduinoJson v 6.20.0 library. I've done different tests with it, and actually the solution is to use the v6.19.4 of the ArtuinoJson library. Keep on mind that I have two version of the CTBot:
- the first is published and is the 2.1.9 that use
Stringvariables - the other is the 3.0.0 (published in the v3.0.0 branch - you have to download it manually) that use standard C strings and have a lot of new functionalities Both have the same issue with the ArduinoJson library v6.20.0.
Hoping that helps, cheers.

My issue is identical to an earlier bug reported as 'Kernel panic' , following on from the excellent imformation in that post / reply I set up a basic test using only the following in the loop;
void loop() { TBMessage msg; if (myBot.getNewMessage(msg)) Serial.print("got message"); delay (500); } That little snippet is enough to crash the esp8266. Referring to the exception decode even the most basic library example crashes and in all cases there is a reference to the Wstring.h (Ah, the curse of the 'String' versus the 'C' string!) I have also seen exception 9 too.
Serial monitor output;
Starting TelegramBot...
testConnection OK After a few seconds the esp8266 crashes

I am using the latest version of platformIO under VSC and all libraries are the latest versions.
Further to my earlier comments I installed the Arduino 2.0.3 IDE along with allowing all library and board updates. Initially before the library / board updates I did successfully compile the basic echo example and it ran without crashing BUT it didn't receive or send any messages to telegram. I am of the opinion that either the newer tool chains or library versions break the code resulting in a soft WDT reset. This occurs both under the Ardsuino and platformIO IDE's.
