I've got an ESP8266-01 that is having a problem. It keeps spewing text, the same text to the serial monitor over and over. The blue led on the USB TTL interface and the ESP8266 keeps flickering non-stop. Not sure what's going on? The text is legible...it look like it's part of the esp8266s firmware.
The esp8266 is connected to my PC via a USB TTL interface board. This is an inexpensive CH340 board from eBay. I have it plugged into a breadboard...set for 3.3v. I'm also taking the 5v from the USB TTL interface and running it into a 3.3v regulator which then powers the ESP8266.
ESP USB TTL
VCC = 3.3v (from 3.3v reg)
GND = GND
CP_PD = VCC
RXD = TXD
TXD = RXD
GPIO0 floats except when updating firmware, then it is connected to GND
GPIO2, RST are floating (no connection).
Any ideas? Suggestions?
