Application Development Guide

Create a product and obtain the product PID​

Refer to the documentation https://developer.tuya.com/en/docs/iot-device-dev/application-creation?id=Kbxw7ket3aujc to create a product on https://iot.tuya.com and obtain the PID of the created product. Replace the TUYA_PRODUCT_KEY macro in the apps/tuya_cloud/switch_demo/src/tuya_config.h file with the PID.

Confirm the TuyaOpen authorization code​

The Tuyaopen Framework includes:

All versions use TuyaOpen dedicated authorization codes. Using other authorization codes will not allow normal connection to the Tuya Cloud.

[tuya_main.c:220] Replace the TUYA_DEVICE_UUID and TUYA_DEVICE_AUTHKEY contents, otherwise the demo cannot work
[tuya_main.c:222] uuid uuidxxxxxxxxxxxxxxxx, authkey keyxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

The dedicated authorization code for TuyaOpen can be obtained through the following methods:

  • Method 1: Purchase a module with a TuyaOpen authorization code pre-burned. The authorization code is already burned in the corresponding module at the factory and will not be lost. TuyaOpen reads the authorization code through the tuya_iot_license_read() interface at startup. Please confirm whether the current device has a TuyaOpen authorization code pre-burned.

  • Method 2: If the current module is not pre-burned with a TuyaOpen authorization code, you can purchase an Open SDK Authorization Code through the https://platform.tuya.com/purchase/index?type=6 page and put 'TUYA_DEVICE_UUID' and 'TUYA_DEVICE_AUTHKEY' in the apps/tuya_cloud/switch_demo/src/tuya_config.h file Replace the uuid and authkey obtained after successful purchase

Authorization Code

tuya_iot_license_t license;

if (OPRT_OK != tuya_iot_license_read(&license)) {
   license.uuid = TUYA_DEVICE_UUID;
   license.authkey = TUYA_DEVICE_AUTHKEY;
   PR_WARN("Replace the TUYA_DEVICE_UUID and TUYA_DEVICE_AUTHKEY contents, otherwise the demo cannot work");
}

If the tuya_iot_license_read() interface returns OPRT_OK, it indicates that the current device has a TuyaOpen authorization code pre-burned. Otherwise, it indicates that the current module is not pre-burned with a TuyaOpen authorization code.

Build and Flash​

  • Run the tos config_choice command to select the current development board in use.
  • If you need to modify the configuration, run the tos menuconfig command to make changes.
  • Run the tos build command to compile the project.
  • Use the tos flash command to flash the project in one click.

For more details about tos, please refer to tos Guide.

Network Configuration and Device Activation​

Use the Tuya APP to configure the network via Bluetooth or Wi-Fi AP mode and activate the device.
