Self-checking message synchronization method based on Bluetooth device and wireless local area network

The invention discloses a self-checking message synchronization method based on a Bluetooth device and a wireless local area network. A host or a guest comprises a message monitoring module, a notification screening module, a Bluetooth module, a local area network host module, a host checking module, a local area network guest module, a guest checking module, a message sending and receiving module, a clock module and a notification generation module. The modules are activated depending on actual situation. When the host receives the message notification, the guest can also synchronize the message. Meanwhile, uninterrupted message intercommunication is carried out between the host and the guest, so that delay caused by fluctuation of the server can be avoided, and connection can be kept inBluetooth and a local area network. Once the data are disconnected, a user can be notified in time to remove faults, and double insurance is achieved. The method has very important significance in message synchronization betw
