Module package size seven. 2 antenna design guidelines, the inverted-F antenna 12 eight, nine application reference design schematics, design considerations 1. Regarding the use of Bluetooth wireless environment, including Bluetooth wireless signals are greatly affected by the surrounding environment, such as trees, metal and other obstacles material will absorb a certain radio signal, so in practice, the distance data transmission by a certain extent. 2. Since Bluetooth module supporting software have placed in the housing. Since the metal shell on the radio frequency signals are shielded effect. It is not recommended to be installed in a metal housing. 3. PCB Layout: PCB antenna Bluetooth module, the metal will weaken the function of the antenna, the antenna area when not in LAYOUT shop copper or traces. 4. The bottom of the module as little as possible traces GND maintain integrity, and RF antenna GND pins on both sides as complete as possible.
