Tuya IoTOS Embeded Demo WiFi & BLE Smart Smoke Sensor

English | 中文

Introduction

This Demo implements a smart smoke detection 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 include.

• Real-time detection of smoke values in the environment and alarm alerts when a certain threshold is reached.

Quick start

Compile & 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-smoke-sensor

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

  sh build_app.sh apps/tuya-iotos-embeded-demo-wifi-ble-smoke-sensor tuya-iotos-embeded-demo-wifi-ble-smoke-sensorr 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 function: device_init()

• Call tuya_iot_wf_soc_dev_init_param() interface to initialize the SDK, configure the operating mode, the wiring 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()

DataPoint 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
