 a) Why module can not communicate properly?

1) Check the band, channel, rate, NET ID is set to the same;
2) The power connection error, the module is not working;
3) Module is enabled (CS high);
4) The antenna connection is not correct;
5) Module is damaged.

b) Why far transmission distance?
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 is receiving data correctly?
1) Improper parameter settings;
2) Module data interface is bad.
