FAQ:

A. Why module cannot communicate properly?

1) Check if there is a power connection error;

2) Check if the module is enabled (CS / SET both high);

3) Check if the band, channel, rate, NET ID has set to the same;

4) Check if the module is damaged(light is on?)

B. Why transmission distance is not as far as it should be?

1) Power supply ripple is too large;

2) The antenna types do not match, or not properly installed;

3) The surrounding environment is harsh, strong interference sources;

4) Surrounding co-channel interference;

C. Why receiving data incorrect?

1) Check if the interface compatible with the device;

2) Improper parameter settings.

3) The module data interface is bad.
