I bought a 3.3V power supply specifically for this project.
I don't have a FTDI cable, so I am using the Arduino Uno and the IDE's Serial Monitor to talk to the ESP8266.
I am also using a level shifter board. TX is going to RX and RX is going to TX through the level shifter board.
When powered up, I get a bunch of odd charachters and then
Ai-Thinker Technology Co.,Ltd. ready
The Serial Monitor is set at 115200 with CR.
Yet, I don't get a response to AT
My smartphone sees AI-THINKER_D1D543, so the module is alive.
I just can't talk to it.
What am I doing wrong?
TX to TX
RX to RX
works (Serial Monitor shows text from ESP8266)
TX to RX
RX to TX
does not work
