I'm testing my first ESP8266 WiFi module (with ESP-01 Adapter, with 3.3V, & level conversion)
My question is, after setting the baud rate last night, testing, and getting a good AT+GMR response, it now powers on to a steady Blue LED with no response to AT commands. Only an echo '>>>> AT' of the command sent.
This condition occurs when powered by outboard 5V power supply or Arduino. The adapter board has only 4 pins, TX, RX, Gnd, VCC.
I have not Flashed the ESP8266, and didn't want to.
What could cause this solid Blue suddenly?
Any guidance appreciated.
