The Wi-Fi and Bluetooth solution for smart fan devices with Tuya WBRU network modules.

Tuya IoTOS Embedded Wi-Fi & Bluetooth LE Smart Fan (WBRU)

English | 中文

Introduction

In this demo, we will show you how to retrofit an ordinary fan and make it IoT-enabled. Based on the Tuya IoT Platform, we use Tuya's Wi-Fi and Bluetooth LE combo module, SDK, and the Tuya Smart app to connect the fan to the cloud.

Get started

Compile and flash

• Create a product on the Tuya IoT Platform and download the SDK in the third step of Hardware Development.

• Clone this demo to the demos folder in the downloaded SDK.

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

  Note that the build.sh file is only used for SDK earlier than v2.0.3.

• Run the following command in the SDK root directory to start compiling.

  sh build_app.sh demos/tuya_demo_bldc_fan tuya_demo_bldc_fan 1.0.0

• For more information about flashing and authorization, see Flash Firmware to and Authorize WBR Modules.

Entry to application

Entry file: /demos/src/tuya_device.c

Main function: device_init()

• Call tuya_iot_wf_soc_dev_init_param() for SDK initialization to configure working mode and pairing mode, register callbacks, and save the firmware key and PID.
• Call tuya_iot_reg_get_wf_nw_stat_cb() to register callback of device network status.
• Call fan_device_init() for application initialization.

Data point (DP)

• Report DP data: dev_report_dp_json_async()

  Function	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	For gateways and devices built with the MCU or SoC, the devid is NULL. For sub-devices, the devid is sub-device_id.
  dp_data	The name of DP struct array
  cnt	The number of elements in the DP struct array
  Return	OPRT_OK: success. Other values: failure.
