Tuya Environment Monitor Demo Through IoTOS Embedded Wi-Fi and Bluetooth Low Energy SDK

English | 中文

Overview

This demo describes how to develop an environment monitor by using the Tuya IoT Platform, Tuya Smart app, and IoTOS Embedded Wi-Fi and Bluetooth Low Energy SDK. It uses Tuya Wi-Fi modules and Wi-Fi + Bluetooth Low Energy modules to provide smart functions such as remote data monitoring and remote automatic control.

The following features have been implemented:

• Flame detection

• Smoke detection

• Combustible gas detection

• PM2.5 detection

• Formaldehyde detection

• Auto power off

Get started

Build and flash

• Download Tuya IoTOS Embedded Wi-Fi & Bluetooth Low Energy SDK.

• Download the demo to the apps directory of the SDK directory.

  $ cd apps
  $ git clone https://github.com/tuya/tuya-iotos-embeded-demo-wifi-ble-environment-monitor

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

  sh build_app.sh ./apps/tuya-iotos-embeded-demo-wifi-ble-environment-monitor tuya-iotos-embeded-demo-wifi-ble-environment-monitor 1.0.0 

• For more information about firmware flashing and authorization, see Wi-Fi + BLE Modules.

Demo entry

Entry file: tuya_device.c

Important functions: device_init()

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

• Call the tuya_iot_reg_get_wf_nw_stat_cb() interface to register the callback function of the device network status.

• Call the application layer initialization function air_box_device_init().

Data point related interface

• Report the DP through 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	The device ID (if the device is a gateway, MCU, SOC device, then devid = NULL. If it is a sub-device, then devid = sub-device_id)
dp_data	The DP struct array name
cnt	The number of elements of the DP struct array
return	OPRT_OK: success, other: failure
