1. WB822D Module is designed based on nRF51822 RF SoC chip of NORDIC company.

2. nRF51822 is an ultra-low-power 2.4GHz wireless System on Chip (SoC) integrating the nRF51 series 2.4GHz transceiver, a 32bit ARM Cortex-M0 CPU, flash memory, and analogue and digital peripherals.

3. nRF51822 can support Bluetooth low energy and a range of proprietary 2.4GHz protocols, such as Gazell from Nordic Semiconductor.

A method of enabling communications between a Bluetooth low energy master communication device in a vehicle and a slave communication device. The slave communication device is successfully paired with a Bluetooth high energy master communication device in the vehicle. An identifier of the slave communication device is stored when it is successfully paired with the Bluetooth high energy master communication device. The Bluetooth low energy master communication device identifies an advertising event broadcast by the slave communication device. The advertising event relates to a notification by the slave communication device of the availability of its services. A determination is made whether the identifier of the slave communication device matches the stored identifier. Wireless communications between the Bluetooth low energy master communication device and the slave communication device is autonomously established without a manual pairing operation in response to an identifier of the slave communication device matching
