Introduction
The Bluetooth Class 2 Module (model number
BM-GP-CS-08) is a small module with 10-way
connector that provides a complete 2.4GHz
Bluetooth system. This ready-to-use Class2
Bluetooth module provides a fully compliant
Bluetooth system V1.2 for data and audio
communications.
This module also provides the coexistence
solution that is critical for Notebook
implementation. The coexistence solution
includes AFH, and WCS (Wireless
Coexistence Solution). Activity Signaling is an
option.

Mounting Guide for Antenna Radiation
In order to achieve longest communication range, please keep the area surrounding antenna free of grounding
or metal housing.

Impedance Matching of Antenna
BM-GP-CS-08 utilizes a meander line printed antenna for radiate communication.
Application environments, such as notebooks, PDAs, headsets or other handheld devices,
both have plastic housings, different motherboards and other mechanism structures. These
factors will cause the deviation of antenna resonant frequency. Therefore, impedance
matching of antenna should be optimized for various applications to achieve longest
communication range. Please consult USI for further information.
