Recommended for new designs where back compatibility
to older devices is not required
Encryption algorithm is created and owned solely by
LPRS. It uses a 16-bit seed that can be set by the
developer.
The CRC16 routines are more efficient and secure than
the old CRC8. For new applications it is recommended.
When enabled, this mode will simply echo EVERY
message is hears. Therefore no more than 1 repeater
should be used UNLESS specific rules are followed.
An application note will be available shortly to explain this
further.
This feature allows you to transmit on a different channel
frequency to the receive frequency.
e.g. ER_CMD#F07
After reselecting channel 0, the module will listen on CH0
but transmit on CH7.
To reset the module to its default, send the same source
channel number to the destination:
e.g. ER_CMD#F00
Warning DCS should be disabled to use this feature.
