Design notes:

In order to bet the SNR, please pay at tent ion to the hardware design of PA, DC booster, DC/DC circuit and the module power circuit to avoid int luencing module.
le signal strength is depending on the environment of Bluetooth application 10 ich as wood and metal will block the transmission signal to get a shorter transmission distance.
Because of metal will block the signal transmission, it is recommended not to use the metal housing.

PCB layout guideline:
no copper existed in the antenna area of the module is the PCB antenna, the metal will weaken the function of the antenna when the antenna module to the module board, following prohibited paving and walking the line.
If the module antenna is next to the battery or metal, liquid crystal screen, or loudspeaker, at least keep them away from the antenna distance of 15mm.
When laying out the power supply line recommend star line, and to ensure that the Bluetooth module Power supply lines is better, and BT should be with the amplifier, power amplifier, MCU, separately, and the underside of the BT has no other interference.
Suggests the module antenna part floating on the floor, do not go around the antenna control line, power line, audio line, or MIC interference lines;
If the module antenna is near the row seats, Because of metal will block the signal transmission, it is recommended to use a professional high-gain antenna.

Module Position Guide and SMT profile
Ground must not exist around Antenna area.
