Wi-Fi_IR Remote Controler

Using an infrared remote control via Wi-Fi. Connect old devices to the internet.

简体中文

Introduction

This project is designed to integrate legacy devices into the Internet of Things (IoT), enabling Wi-Fi access and control.

Additionally, this project also functions as an infrared development device. It can receive infrared signals for debugging purposes.

Feel free to submit Issues and PRs to improve the project together.

Technologies/Hardware Used

The hardware component is implemented using the ESP12F (based on ESP8266). The control software is written in Swift and can run on macOS, iOS, and iPadOS. This is a web-based control project, allowing you to easily develop your own control interfaces.

Usage

Hardware Section

Preparation

Soldering and Flashing

Solder the ESP12F onto the PCB, connect to the chip using a microcontroller communication tool, and flash the firmware.

Power On

Power on the flashed chip. The indicator light will stay solid during initialization and switch to blinking once completed.

(Refer to Indicator Status for explanations.)

Initial Setup

Connecting to Wi-Fi

1. Turn on an internet-capable device and connect to the Wi-Fi with SSID Gl Device Connect. The device will automatically open the provisioning page.

   Note: If the page doesn’t open automatically, visit: http://192.168.4.1.

2. Select your Wi-Fi network, enter the password, click "Connect," and the device will reboot.

Connection

After rebooting, if initialization is successful and Wi-Fi is connected, the indicator will briefly blink and then stay solid, indicating success. If it continues blinking, the connection failed—repeat the Connecting to Wi-Fi steps.

Placement

Position the device so that the infrared LED faces the target device or its signal can reflect onto it.

Usage

Controlling the Device via App

(Refer to the Software section.)

Controlling the Device via HTTP (API)

Sending Infrared Commands

Request: http://ip/IRControl

Parameters:

Parameter	Format	Method	Required
IRSign	String (Hex)	GET	Yes

Response:

Return Value	Meaning
Success	Command sent
Null / No response	Failed to send

Receiving Infrared Commands

Request (GET): http://ip/IRReSend

Return Value	Meaning
String (Hex)	Infrared data
Null	No data

Note: Poll this endpoint (recommended interval: 0.1s).

Additional Notes

Indicator Status

Indicator State	Meaning
Solid	1. During power-on: Initializing and attempting to connect to the last-used Wi-Fi. 2. After rapid blinking: Connected to Wi-Fi, ready for commands.
Rapid Blinking	Connected to Wi-Fi.
Blinking	Awaiting Wi-Fi connection (see Initial Setup).

Software

Follow the on-screen instructions for usage.

Note: This software is only intended for API demonstration and device debugging, not for production use.
