  [arduino code examples for DM16]-09 how to communication with Tuya WiFi module
Posted by: admin - 09-09-2025, 03:34 AM - Forum: DM16 - No Replies

Code:
/*
* Made by KinCony IoT: https://www.kincony.com
*
* This Arduino program implements communication between ESP32 and the Tuya module
* via UART (serial communication). It listens for specific packets from the Tuya module
* and responds according to the predefined commands.
*
* Functionality:
* 1. When the ESP32 receives a heartbeat packet (55 AA 00 00 00 00 FF),
*    it sends a heartbeat response (55 AA 03 00 00 01 00 03).
* 2. When the ESP32 receives a product information request (55 AA 00 01 00 00 00),
*    it sends a product information response (55 AA 03 01 ...).
* 3. When the ESP32 receives a work mode request (55 AA 00 02 00 00 01),
*    it sends a work mode response (55 AA 03 02 00 03 10 1C 14 47).
* 4. When the ESP32 receives a network status request (55 AA 00 03 00 01 00 03),
*    it sends a network status response (55 AA 03 03 00 00 05).
* 5. Subsequent heartbeat packets (55 AA 00 00 00 00 FF) are responded to with
*    (55 AA 03 00 00 01 01 04).
