ESPRemoteSerial

Remote (network) serial monitor for ESP8266 & ESP32.

Features

• Self-hosted ESP network monitor that emulates the Arduino serial monitor
• Useful for debugging and development on remote ESP-based systems
• Automatically prints to local serial if initialized
• Well-suited for use with arduinoOTA update
• Works with mDNS for accessing via a local hostname rather than IP address

Installation

1. Install the dependencies, and their required dependencies, from the section below.
2. Add this library to the Arduino library, either by downloading it and adding it as a .zip, copying it locally into the libraries folder, or adding this repo address into the Arduino library manager list.
3. #include <ESPRemoteSerial.h> in your .ino sketch file.

Dependencies

• ESPAsyncWebServer
• Log4Esp
• NTPClient (Only if compiled with USE_NTPCLIENT, which is on by default)
• SPIFFS (ESP internal) is required to store the local logfile. It won't yet work without the filesystem present.

Usage

See complete examples in the examples directory.

Printing to remote log

Call ESPRemoteSerial::print(). Supports formatters in the same way printf() or std::cout does.

remoteSerial.print("setup() complete | T = %u", millis());

Viewing remote log

Visit http://local_ip_or_host/log (i.e. 192.168.1.101/log) or the hostname if using mDNS (i.e. wifithingy.local/log). Since the logger is persistent, it will load messages logged before loading the remote log.

To-do

1. Locally include Bootstrap and jQuery and inline them into log.html (for networks without internet access, since these files are currently fetched from their respective CDNs)
2. RAMDisk logging as an option to eliminate the need for a SPIFFS partition
