Parameter Mode
The parameter mode uses the "Proprietary A" PGN 0x00EFnn for a peer-to-peer
communication. Therefore the PGN includes the sensor node address in the last byte.
To read and write the parameters the eight data bytes have to contain the following commands.
The written parameter values are saved permanently when the parameter mode is left. Then
the sensor starts with a complete reset and the new parameter set.
5.6
Starting Parameter Mode
To send parameters to the device and to read out the actual parameters start the parameter
Mode by using the following sequence.
*: placeholder, necessary
nn: destination address -> sensor node address
rr: source address
xx: unused, bytes optional
5.7
Reading Parameters
To read out the actual parameters use the following message.
*: placeholder, necessary
pp: the index of the parameter (see chapter "Parameter Table")
nn: destination address -> sensor node address
rr: source address
