Tuya IoTOS Embeded Demo WiFi & BLE Smart BLDC Fan

English | 中文

Introduction

This Demo implements a smart fan through Tuya Smart Cloud Platform, Tuya Smart APP, IoTOS Embeded WiFi &Ble SDK, using Tuya WiFi/WiFi+BLE series modules to achieve remote data monitoring.

Implemented features.

• BLDC Motor speed increases with decreasing PWM duty cycle**
• Rotary switch (encoder) Press the switch, rotate clockwise to increase the wind speed by one gear, rotate counterclockwise to decrease the wind speed by one gear
• app control, timer on/off, 3 modes (normal wind, natural wind: big and small intervals of 5 seconds, sleep wind: automatic downshifting every hour), power-off memory

Quick start

Compile and burn

• Download Tuya IoTOS Embeded WiFi & BLE sdk

• Download the demo to the apps directory of the SDK

  $ cd apps
  $ git clone https://github.com/Tuya-Community/tuya-iotos-embeded-demo-wifi-ble-blde-fan

• Execute the following command in the SDK root directory to start compilation.

  sh build_app.sh apps/tuya-iotos-embeded-demo-wifi-ble-blde-fan tuya-iotos-embeded-demo-wifi-ble-blde-fan 1.0.0 

• Firmware burn-in license information please refer to: Wi-Fi + BLE series module burn-in license

Demo entry

Entry file: tuya_device.c

Important functions: device_init()

• Call tuya_iot_wf_soc_dev_init_param() interface to initialize the SDK, configure the operating mode, the mating mode, and register various callback functions and store the firmware key and PID.

• Calling the tuya_iot_reg_get_wf_nw_stat_cb() interface to register the device network status callback functions.

• Call the application layer initialization function air_box_device_init()

DP point related

• Report dp point interface: dev_report_dp_json_async()

function name	OPERATE_RET dev_report_dp_json_async(IN CONST CHAR_T *dev_id,IN CONST TY_OBJ_DP_S *dp_data,IN CONST UINT_T cnt)
devid	device id (if gateway, MCU, SOC class device then devid = NULL; if sub-device, then devid = sub-device_id)
dp_data	dp structure array name
cnt	Number of elements of the dp structure array
return	OPRT_OK: Success Other: Failure
