Remote Serial monitor for ESP8266 & ESP32

WebSerialLite

WebSerial is a Serial Monitor for ESP8266 & ESP32 Microcontrollers that can be accessed remotely via a web browser. Webpage is stored in program memory of the microcontroller.

Upgrade to Pro?

I'm sorry that the current version is already the Pro version. XD

Features

• Works on WebSockets
• Realtime logging
• Any number of Serial Monitors can be opened on the browser
• Uses Async Webserver for better performance
• Light weight (<3k)
• Timestamp
• Event driven

Dependencies

For ESP8266:

• ESP8266 Arduino Core - (latest)
• ESPAsyncTCP - v1.2.2
• ESPAsyncWebServer - v1.2.3

For ESP32:

• ESP32 Arduino Core - (latest)
• AsyncTCP - v1.1.1
• ESPAsyncWebServer - v1.2.3

Documentation

WebSerialLite is very similar to the default Serial Monitor Library of Arduino.

Please see Demo examples for better understanding on how to setup WebSerialLite for your Project.

WebSerialLite has 2 main functions:

• print
• println

print - simply prints the data sent over WebSerialLite without any newline character.

println - prints the data sent over WebSerialLite with a newline character.

Both functions support the following datatypes: String, const char, char, int, uint8_t, uint16_t, uint32_t, double, float.

To Access WebSerialLite: Go to <IP Address>/webserial in your browser ( where <IP Address> is the IP of your ESP).

FAQ

1. last println not being received #4

   This issue is not caused by this library. As you can see in https://github.com/me-no-dev/ESPAsyncWebServer/blob/f71e3d427b5be9791a8a2c93cf8079792c3a9a26/src/AsyncWebSocket.cpp#L550 , they limit the length of queue, and they define the max length of queue to 8 for ESP8266, you can check in https://github.com/me-no-dev/ESPAsyncWebServer/blob/f71e3d427b5be9791a8a2c93cf8079792c3a9a26/src/AsyncWebSocket.h#L30.

   So if you want to send many messages through websocket rapidly, I recommend you make a temp storage. Or you can edit the ESPAsyncWebServer to solve this problem. By the way, I create a PR try to let user config the WS_MAX_QUEUED_MESSAGES (esphome/ESPAsyncWebServer#10), hope it can be proved.
