Note
：
1. The module transmission data rate will affect Transmission distance, the higher the data rate, the closer
the distance, and the lower the receiving sensitivity.
2. The supply voltage to the module will affect TX power, in the operating supply voltage range, the lower
the voltage to get the lower the TX power.
3. The antenna will strongly affect the communication distance, please select matched antenna and connect
it correctly.
The module mount will affect the communication distance.
