While it doesn’t seem to be an issue with your code, I’d like to take a chance to check out your setup and see what I’m missing.
Using the WiFi chip as it’s own hotspot instead of connecting to the phone or another mutual network seems to be just the trick to get serial access to the commands sent to the chip, which was where I got stuck.
(Oh, your diagram has an error in it, with the LED connection; and the code needs a few of your debugging lines commented out.)
