Bluetooth disconnects from the device

Phenomenon: The connection between Bluetooth and the device will be interrupted after 5 minutes of exceeding the connection range, and it needs to be restarted to connect.

Troubleshooting steps:

1. The optimal distance for the Bluetooth connection between the device and the mobile phone is within 10 meters.
2. If the device detects that there is no connection, for the purpose of saving power, the device will automatically turn off the Bluetooth module after five minutes (the Bluetooth module has certain power consumption). Please reopen the Bluetooth module to reconnect.
