instead of the CH340 debugger I can use a usb ft232rl to program ESP8266
I am using the BTT Writer with the Wifi Module from BTT as well. I have verified this issue on 2 different PCs now. Wiring is exact as diagram provided this is my platformio.ini below. I have tried ck instead of nodemcu and even followed this video (https://www.youtube.com/watch?v=NGgzw-XayEo&t=684s) with no success.
