Tuya IoTOS Wi-Fi and BLE Indoor Garden Demo

中文版 | English

Overview

This demo describes how to implement a smart indoor garden through Tuya IoTOS SDK. With Tuya Cloud, Tuya Smart app, and Tuya Wi-Fi or Wi-Fi+BLE modules, you can easily implement IoT-enabled functions such as remote control, data monitoring, and remote control.

Implemented functions:

• Light monitoring
• Temperature and humidity monitoring
• Soil moisture monitoring
• Water tank level monitoring
• Automatic light filling
• Automatic spraying
• Automatic heating
• Automatic ventilating
• Automatic water tank filling
• Automatic watering

Quick start

Download and compile

• Download Tuya IoTOS Wi-Fi and BLE SDK

• Download the demo to apps directory under the SDK directory

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

• Execute the following command in the SDK root directory to start compiling:

  $ cd ../
  $ sh build_app.sh apps/tuya-iotos-embeded-demo-wifi-ble-smart-planter tuya-iotos-embeded-demo-wifi-ble-smart-planter 1.0.0

Demo entry

Entry file: tuya_device.c

Important functions: device_init()

• Call tuya_iot_wf_soc_dev_init_param() to initialize the SDK, configure the operating mode and pairing mode, register callback functions, and store the firmware key and PID.
• Call tuya_iot_reg_get_wf_nw_stat_cb() to register the network status callback function.
• Call application layer initialization function app_plant_init().

DP related

• Data flow of DP sending: dev_obj_dp_cb() -> deal_dp_proc()
• API of DP reporting: 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 the device is a gateway, MCU, or SoC, devid is NULL. If the device is sub-device, devid is sub-device_id.
dp_data	The name of DP struct array.
cnt	The number of DP struct arrays.
Return	OPRT_OK: Succeeded. Other: Failed.
