Attention
Bluetooth works at the frequency of 2.4ghz, so influences of various factors on wireless
transceiver should be avoided as far as possible. The following points should be noted
：
 Avoid using metal as part of the product housing surrounding the module. If the housing is metal,
consider using an external antenna
。

The metal screws inside the product should be kept away from the RF part of the module。
 To maximize RF performance, the user host board layout should follow the following
recommendations：
1)
Antenna clearance area: there shall be no copper foil routing (package) directly below the
antenna area of the user's motherboard(Including power supply, ground and signal layer).
2)
Module position: ideally, the module should be arranged in a corner of the user's
motherboard, PCB The antenna is located far from the motherboard End. This position minimizes the
clearance area of the antenna.
