Hi.
Firstly, thank you for your work on this project and for sharing it in the public domain. I am always impressed by the selfless work that developers do and then share for no personal gain. It warms my heart and makes me feel that I need to do more to improve humanity!
Thank you! Thank you!.
I have been trying to upload your firmware to a esp8266EX based module and Ubuntu 20.04 PC, without success.
The firmware upload fails with the following terminal output.
