Generating random packets

Post by justinklchan2 »

As part of a university research project, I would like to generate random Z-wave packets with the Z-uno board and capture the packets with a software-defined radio.

I do not have any other Z-wave products or peripherals.

Is it possible to generate random Z-wave packets with the Z-uno? If so can anyone point me to an example sketch or outline what commands I would use to do this?

If this is not possible with the Z-uno, is it possible with the UZB? And if so how might I do that.

If it cannot be done with the Z-uno or UZB how might I go about doing this?

Z-Uno do not have a function for random. Though internally we have such a function based on radion noise (means pretty "white" in distribution).

For now you can send reports to the associated controller (set up association first) and send some byte that is calculated based on X mod N, so it will be pretty random. It will jot be random, but highly jumping values.

In future we might open the random function to the user (easy to do).

With UZB you can do much note as in Z-Way you have full access to crypto functions and random and you can generate longer packets
