Huawei watch gt2 looking for Nubian z40Pro phone doesn't ring.

The Bluetooth that should be connected to the mobile phone is disconnected.

After Huawei watches use the mobile phone function, the reason why the mobile phone does not ring is that the Bluetooth connection between the mobile phone and the watch is disconnected, and the watch cannot transmit instructions to the mobile phone. There are two main reasons why the Bluetooth connection between them is disconnected: the Bluetooth function of the mobile phone is not turned on. The watch cannot be connected to the mobile phone, nor can it send instructions to the mobile phone. The distance between the mobile phone and the watch is beyond the range of Bluetooth connection. We know that Bluetooth technology can connect devices wirelessly within a certain distance, and with the continuous progress of Bluetooth technology, the transmission distance of Bluetooth is also increasing, and the Bluetooth version of Huawei watches is also 5. Above 0, the current mainstream mobile phone Bluetooth version is also at 5. Above 0, theoretically it can be connected within 300 meters. But in reality, the strength and distance of Bluetooth connection are also related to the environment, such as signal interference such as walls, which will affect the transmission distance. Therefore, the Bluetooth connection is easily disconnected because the distance is too far and the signal is too weak.
