== Frequency & Encryption ==
To make the module communicating together:
* The module must be identical. You cannot mix them.
* The tuned frequency must be identical.
* The encryption key must be identical.
{{underline|Tuned frequency:}}
The tuned frequency is declared with a line like this:
if (!rf69.setFrequency(RF69_FREQ)) {
Serial.println("setFrequency failed");
}
where the tuned frequency is declared with the constant '''RF69_FREQ'''.
#define RF69_FREQ 433.0
