Hi David,
Generally, this sounds like in principle, your application looks like
(nb: not an actual GR flowgraph)
+-----------------+ +------+
| sample source a |------------>| USRP |---> [USRP1]
+-----------------+ | |
| sink |
+-----------------+ | |
| sample source b |------------>| |---> [USRP2]
+-----------------+ +------+
Let's assume a is continuous and b starts later, or bursts or the like.
Can't you just split the flow graph into two independent flowgraphs,
syncing the USRPs using time stamps?
Alternatively, what about having a block that (rate limitedly) produces
zero-samples, unless data comes in on a message port?
Generally, using start-of-burst tags, the newly added command time
message interface for the uhd blocks, and multiple ways to detangle your
sample streams, there are many ways to solve your issues.
I think it would be wise if you described your setup in a little more
detail.
Greetings,
Marcus
