Software Serial Arduino controls ESP8266 12E
Posted: Sun Sep 18, 2016 6:36 pmI am having a very difficult time with a simple UART connection.
Specifically I have the mega328p chip on and pin numbers 13 (RX) and 14 (TX), which correlate to the Arduino D9 (RX) and D10 (TX) to the ESP8266.
I am able to confirm the ESP8266 is operating at 9600 baud rate, I changed it using the AT+CIOBAUD=9600 on a separate device.
Then I install it on the device that I am having troubles with.
I cannot get the Software Serial to talk to the ESP8266 12E chip.
VCC 3.3V is on the EN and VCC, GND = GND, RX = D9 and TX = D10 (I've tried flipping these RX/TX lines to no success) Ground is common, and Voltage Regulator supports 550mA.
