128-bit AES encryption can be enabled between RF devices using a 16 character private key that is sent to each device before enabling encryption.
The 16 Character encryption key should be sent to each device through the serial port. Refer the hardware and firmware section of this documentation for serial port connection details for the device you have.
Frequency Default Setting
Encryption is off by default and and the 16 character password is 16 spaces.
How to enable encryption
Configure the encryption key pass-phrase
Where: p1 = is a 16 character pass-phrase p2 = the first 5 characters of the pass-phrase
The below example sets the pass-phrase to MyPassPhrase1234:
python rf_config.py 03 ATEAMyPassPhrase1234 SENT : 03ATEAMyPassPhrase1234 RECEIVED : 03ATEAMyPas
Where: p1 = is 1 for on and 0 for off
The below example enables Encryption:
python rf_config.py 03 ATEE1 SENT : 03ATEE1 RECEIVED : 03ATEE1
The device with device ID 03 will now encrypt all outgoing messages and decrypt incoming messages
