Hi everyone,
I have several USRP N210 and I want all of them to transmit using the same frequency. Since I cannot use FDMA (this is one of my requirements, not a GNU Radio/USRP limitation) then I thought I would give TDMA a try.
I want to be able to tell a node not to transmit when it is not its turn and to transmit when its turn comes up. I saw the tag feature of GNU Radio (tx_sob, tx_eob in particular) but I do not know how to use them from my python flowgraph.
I tried using pre-cog which compiles fine but some blocks seem to be missing because of grextras which doesn't even pass the cmake step with my GR3.7.3 install.
