BNEP is called Bluetooth Network Encapsulation Protocol (Network Encapsulation Protocol, hereinafter referred to as BNEP). BNEP is designed for PAN applications and provides an application model for constructing bluetooth wireless lan, and BNEP can perform mapping network protocol hierarchy from IP layer to L2CAP layer as shown in fig. 1. The bluetooth personal area Network provides networking capability for bluetooth devices by using BNEP, so that two or more bluetooth devices form a temporary ad hoc Network (GN), or Access a remote Network through a Network Access Point (NAP). BNEP provides translation of the bluetooth protocol stack and the TCP/IP protocol stack, and IEEE802.3 ethernet encapsulation supports the same upper layer network protocols. The MTU of the BNEP payload area locates 1691 bytes, which can ensure one-time transmission of Ethernet layer packets sent downwards by the network layer. In terms of data transfer, BNEP directly receives the ethernet packet sent down by the IP layer, and directly copies the ethernet payload area to the BNEP payload area, and sends the resulting area to the L2CAP layer after adding the BNEP header.

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 traditional POS, or an intelligent POS product.
