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.

also seeing this with 4 other esp01 / 8266 devices

I tried the original btt wifi module that I ordered with my SKR, it worked at first, broadcasted ssid, allowed me to upload files, and then, it just served a blank page. this was after uploading the favicon.ico file.

I tried wiping it and rewriting, which goes fine, but not it does not broadcast an ssid.

I decided to purchase 4 more esp8266 devices from amazon, as they had the same exact specs, pins, etc. they all wont connect to the writer.
