it only returns the WL_NO_SSID_AVAIL error. This code works (connects to the designated SSID on EVERY other ESP32 card I have in my shop (many).
Why would it not run on this card?
Note that the SSID does have "/0" at the end of it but again, this code works for every other ESP32 card I have.
Note: I have also tried all three power WiFi Output Levels.
Any ideas? (big time sink this...)
Thanks!
