BNEP is collectively referred to as Bluetooth Network Encapsulation Protocol (network encapsulation protocol, hereinafter BNEP). BNEP is designed for PAN applications and provides an application model for constructing bluetooth wireless local area networks, which can implement the mapping network protocol hierarchy from IP layer to L2CAP layer as shown in fig. 1. Bluetooth personal area networks use BNEP to provide networking capabilities for bluetooth devices, to enable two or more bluetooth devices to form a temporary Ad-hoc Network (GN), or to access a remote Network via a Network access point (Network Access Point, NAP). BNEP provides conversion of the bluetooth protocol stack and the TCP/IP protocol stack and the IEEE802.3 ethernet encapsulation supports the same upper layer network protocol. The MTU of the BNEP payload area locates 1691 bytes, which can ensure the one-time transmission of the ethernet layer packet sent downwards by the network layer. In terms of data transfer, the BNEP directly receives the ethernet packets sent down by the IP layer and copies the ethernet payload directly into the BNEP payload, plus the BNEP header, before sending to the L2CAP layer.

Preferably, the mobile device end 2 is a mobile phone, the connection network between the mobile device end 2 and the background server 3 is 3G/4G/5G/WIFI, and the POS terminal 1 is an MPOS, a conventional POS or an intelligent POS product.
