Abstract

A device for supporting wireless communication is provided. The device includes a first Bluetooth transceiver for connecting to a Bluetooth device, a second Bluetooth transceiver for connecting to a client device, one or more processors, and a memory for storing instructions executable by the one or more processors. The one or more processors may be configured to scan for one or more available Bluetooth devices via the first Bluetooth transceiver, establish a first communication connection with the Bluetooth device via the first Bluetooth transceiver, establish a second communication connection with the client device via the second Bluetooth transceiver, receive data from the client device via the second communication connection, and forward the data to the Bluetooth device via the first communication connection.
