A) Why two wireless rf modules can not communicate properly?
1) Check the wireless module to see if the band, channel, rate, NET ID are set to the same;
2) The power connection error, the wireless module is not working;
3) RF Module is enabled (CS high);
4) The antenna on the RF module connection is not correct;
5) RF Module is damaged.
B) Why the wireless rf module cannot reach longer 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 incorrectly?
1) Improper parameter settings;
2) RF Module data interface is bad.
