Tuya Industry App SDK provides the capabilities to implement multiple device pairing modes, such as the access point (AP) mode, wired mode, sub-device mode, and QR code mode.
- AP mode: also known as the hotspot mode. A mobile phone connects to the hotspot of a smart device. Then, both devices are paired to establish a socket connection between them and exchange data through the specified ports.
- Wired mode: A smart device connects to a router over an Ethernet cable. Zigbee wired gateways and wired IP cameras (IPCs) are paired in this mode.
- Sub-device mode: Bluetooth sub-devices and Zigbee sub-devices are paired in this mode. They interact with the app and the Tuya IoT Development Platform through gateways.
- QR code mode: A smart IPC scans the QR code on the app to get the pairing data.
Currently, the Industry App SDK does not support pairing with Bluetooth devices.
