Before searching for the linked device, you need to turn on the WiFi and Bluetooth functions, and then search and connect the device.
The prerequisite is that you need to install our customized ezblock OS image system to the SD card, and insert the SD card into the Raspberry Pi to boot up. Only then can you proceed to connect the device.
