#ARDUINO MEGA 2560 REV3 PINOUT SERIAL#

Int status = WL_IDLE_STATUS // the Wifi radio's status It uses the WiFiEsp library, so make sure your IDE has it available. I recently used this to add WiFi to a Mega.

#ARDUINO MEGA 2560 REV3 PINOUT SERIAL#

Here is a sketch for an Arduino Mega2560, with an ESP-01 connected to Serial 1. Something in the wiring must be wrong, but that is like a summary of what I found via google. Combinations of 18/19) I cannot get responses from the Module, when I issue AT commands via the Serial Monitor of the Arduino IDE.Īnyone can point me to the one (or many) thing(s), that I am doing wrong?

But although I tried many variants of PIN connections (e.g. I was also able to flash it with the most recent firmware through that USB programming Board. I've tested with the USB programming board, and that worked fine, just I cannot get it to work on the MEGA. My goal is (for now) to communicate via AT commands with the ESP8266 Module on the MEGA. String response = ESP8266.readStringUntil(' ') Serial.println('Command Sent: ' + command) String command = Serial.readStringUntil(' ') SoftwareSerial ESP8266 (rxPin, txPin) // RX, TX My Arduino IDE code for trying the basics of the connection is this: #include Ĭonst byte rxPin = 51 // Wire this to Tx Pin of ESP8266Ĭonst byte txPin = 52 // Wire this to Rx Pin of ESP8266 RXD - PIN 51 via Voltage Reducer from 5v to 3.3v

I connected the ESP8266 module with my Arduino via the attached it the wiring layout (see attached image ESP8266_basic_bb.png), so essentially it is I am struggling since quite some time now, using the ESP8266-01 Module for WiFi connection in my Arduino IDE Project, where I use the MEGA 2560.īefore I am really giving up on it, I thought maybe someone in this forum can guide me to the mistake I am apparently making.
