Three authorization methods are available:
- License list: In the development and debugging phase, this method can be used. You need to purchase the following device information: product key, device name, and device secret, enter it into the code, and compile and flash the firmware.
- Credential: After you develop the firmware and upload it to Tuya IoT Platform, purchase a credential and then use the network module in the production solution for authorization.
- Credential (authorization only): After you create the firmware key on Tuya IoT Platform, purchase the credential (authorization only) and then use independent authorization in the production solution for authorization.
