Authorize Devices

Overview​

For information about licenses, see License.

You can use either of the following authorization methods:

  • Run the authorization command
  • Modify header file

Run the authorization command​

  1. Run the command tos.py monitor -b 115200.

    tip

    Select the serial port number used for flashing.

    tip

    The prerequisite for using this command is that you must be in the application project path (where tos.py build is executed) and the project has been successfully compiled.

  2. Enter the interactive command, use auth, and then press Enter. You will get the following information:

    [INFO]: Run Tuya Uart Tool.
    --------------------
    1. /dev/ttyACM1
    2. /dev/ttyACM0
    --------------------
    Select serial port: 2
    [INFO]: Open Monitor. (Quit: Ctrl+c)
    auth
    auth
    Use like: auth uuidxxxxxxxxxxxxxxxx keyxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
    tuya>

  3. Use auth as prompted to write uuid and authkey.

    tuya>
    auth uuid9f6a6xxxxxxxxxxx cGuDnU2YxjHJldjxxxxxxxxxxxxxxxxx
    auth uuid9f6a6xxxxxxxxxxx cGuDnU2YxjHJldjxxxxxxxxxxxxxxxxx
    Authorization write succeeds.

  4. Use the auth-read command to verify if the authorization was successful.

    The following output indicates successful authorization:

    tuya>
    auth-read
    auth-read
    uuid9f6a6xxxxxxxxxxx
    cGuDnU2YxjHJldjxxxxxxxxxxxxxxxxx

  5. After successful operation, reboot the device for the authorization information to take effect.

    If the device does not support authorization commands, refer to the section below to configure authorization information by modifying the header file.

Modify header file​

  1. Locate the tuya_config.h file in your project directory. The directory might vary by project (check either the src or include directory).

  2. Modify the configuration of the authorization information in the file as follows:

    #define TUYA_OPENSDK_UUID      "uuidxxxxxxxxxxxxxxxx"  // Change to the correct uuid
    #define TUYA_OPENSDK_AUTHKEY   "keyxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" // Change to the correct authkey

  3. Rebuild the firmware, flash it to the device, and then power on the device.
