How does Thonny capture ESP8266 errors?

[Manish Gupta]

Hi everyone,

I’m building a web-based block IDE for ESP8266, and I’m trying to understand how Thonny handles errors.

When my ESP8266 has issues , I can’t initialize the reader/writer on the serial port, so I can’t connect or dump new code. But in Thonny, errors show up clearly and it still recovers.

My question is: how does Thonny read/capture errors from ESP8266?

If anyone can point me to the part of Thonny’s code that handles this, that would really help.
Thanks,
Manish Gupta
