Regarding the use environment of wireless Bluetooth-compatible, wireless signals, including Bluetooth-compatible applications, are greatly affected by the surrounding environment. Obstacles such as trees and metals will absorb wireless signals. In practical applications, the distance of data transmission is limited. influences.
The Bluetooth-compatible module must be equipped with an existing system and placed in the housing. Because the metal casing is shielded from the radio frequency signal. Therefore, it is not recommended to install it in a metal case.
PCB layout: The antenna part of the Bluetooth-compatible module is a built-in antenna. Since the metal will weaken the function of the antenna, when the module is laid, the bottom of the module is preferably hollowed out.
