Software Serial Esp8266 Web
If you get no response, try updating the ESP firmware to the one attached.Use a 3.3v FTDI board like this one- Hookup the ESP to the FTDI- Get the ESP8266Flasher- Get the 1.1.1.1 Firmware Flash the ESP2. If you receive partial response from the ESP8266 when using software serial, go to: C:Program Files (x86)ArduinohardwarearduinoavrlibrariesSoftwareSerialsrcSoftwareSerial.hChange line 42: #define SSMAXRXBUFF 64 // RX buffer sizeTo: #define SSMAXRXBUFF 256 // RX buffer size. This will enlarge the software serial buffer.3.
Sometimes setting the baudrate on initialization fails, try resetting the Arduino, it should work fine.If you have any issues, let us know:).
I am doing a task that send sensor data Through WIFI from esp to PC application to visualize it. All parts of this project done except the one that send the sensor data from UNO to ESP on software serial.Wiring:.connect Rx (0) of UNO to pin (12) in ESP. As Tx.connect Tx (1) of UNO to voltage divider to take 3.3 v to ESP.
Pin (14) as Rx. ground of ESP.
To Ground of UNO. V+ of ESP. To 3v3 of UNO.Code:two codes to test this process if it is working or not.

One on ESP and another on arduinoAfter building I found according to the screenshow below, there is something being send because of the condition of while loop and the delay I set but the output is converted to numbers not string, random numbers! To 3v3 of UNO.The 3v3 pin on a standard Uno will not supply enough current for an ESP8266 to work reliably.Serial on the Uno is connected to Arduino pins 0 and 1, which you're using for output to the Serial Monitor on your computer(as well as uploading sketches). You're also using pins 0 and 1 to communicate with the ESP8266 using software serial.

You can't use the same pins for both these purposes at the same time.
