SmartSDR Discovery Packet requirements

Mark WS7M

Hi all,

I'm working on a fun little bridge project where I have a piece of software that is relaying packets from the Flex radio over a different interface and network.

I understand the Vita packets for the most part but I would like to understand what exactly SmartSDR is looking for in the vita packets to consider one valid.

As one very first stab I tried copying an incoming discovery packet and making changes to the payload data and re-broadcasting it.  This did work and I think the reason is that SmartSDR must be looking at packet counts or other data to determine if the packet is valid.

I of course can construct my own packet but it would be helpful to know what data SmartSDR is concerned with on the UDP packets.

Thanks in advance

I believe what you're looking for can be found in the wiki here.
