Arduino uno esp8266 tutorial serial#

PS: Don't forget to set the line ending in the Serial Monitor to Newline or Carriage Return. If so then you can control it using your Arduino by wiring it back to TX-RX and RX-TX. Now open Serial Monitor and send AT command and see if it responds. Start by uploading blink sketch to your Arduino then connect it to your ESP8266 like this: TX-TX and RX-RX. As noted by others, you need to send - so make sure your Serial window is set to send both (this is a drop-down in the serial window).It probably won't affect simple commands like AT but when you try to connect to a network etc. The Arduino's 3v3 output has insufficient current to support the ESP8266 reliably (50mA Arduino vs up to 300mA for the ESP8266 by some accounts)-try running the ESP8266 off a separate supply.The ESP8266 runs on 3v3, not 5v, so you shouldn't have it directly connected to the digital pins-you need to run through a logic level converter.I'd suggest, based on your description, that this is the most likely culprit that's causing the 'garbage' output you describe. You only need to run this command once (it's a persistent setting). How to change the baud rate on the ESP8266 will depend on the firmware version. Some reports suggest as high as 57600 is workable, though in my experience 9600 is best for reliability. SoftwareSerial isn't capable of 115200 baud rate (despite 'allowing' this as a setting). The ESP8266 works just fine when sending it instructions via the Serial Prompt.Дoes anyone know if what I am trying to do is possible? And if it is, what am I doing wrong?Дoes anyone know if what I am trying to do is possible? I have tested the ESP8266 via the instructions listed in the tutorial in the Resources I've Used section below. set the data rate for the SoftwareSerial port Open serial communications and wait for port to open: The green wire is attached to pin 2 and the yellow wire is attached to pin 3. Same wiring as above, but I have RX and TX reversed. !! I have the green wire attached to pin 3 on the Arduino Uno and the yellow wire attached to pin 2 not 1 and 0 as the picture suggests !! This is the results of running AT+GMR: AT version:0.40.0.0(14:45:58) I have found that I can communicate with the ESP8266 at 115200 baud. Using the Arduino as a pass through (as explained in the tutorial listed in the resources section), I can send AT commands. I either send AT commands and get nothing back ( wiring scheme 1) or I send AT commands and get garbage back ( wiring scheme 2). From Arduino UNO, send AT commands to ESP8266 via a SoftwareSerial port and receive results.
