I think you should use stream tags.In uhd you can send a command with each Burst this command is to be executed by the usrp one command is called tx_freq I think.You can check this through the internet.Br,Osama

I am able to transmit a message and verify the correct content on the receiver side. The next step I want to do is:1. upon sending a specific message (frequency change), I want to change the frequency of the USRP sink (tx side)2. upon receiving a specific message (frequency change) I want to change the frequency of the USRP source (rx side)My question is what will be the best way to do it? I know that I will need to pause the flow graph on tx/rx side, and reload the USRP blocks with the new frequency. But, I dont know when the message will arrive; I cannot do a timing triggering on the flow graph.Thank you in advance.
