FAQ:

 Why module cannot communicate properly?

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

b) Check if there is a power connection error;

c) Check if the module is enabled (CS high);

d) Check if the antenna connection is not correct;

e) Check if the module is damaged.

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

a) Power supply ripple is too large;

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

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

d) Surrounding co-channel interference;

Why receiving data incorrect?

a) Improper parameter settings;

b) The module data interface is bad.
