Re: [Discuss-gnuradio] Tagged Stream Blocks with HackRF

You could give SoapyHackRF [1] a try. From the discussions [2-4] it looks like the Tx/Rx switching is fixed, allowing to put a source and sink block simultaneously in a flowgraph.  The device can switch to RX mode once the burst transmission is done. I am not sure about the Tx/Rx switching timing issues/whether libhackrf makes sure that the entire packet is transmitted or not.  You could also pad your packets with enough zeros to make sure that the packet gets transmitted (Bastian's gr-foo [5] modules will be helpful).

thanks! Do you know if there is someone working on it? Is there some way
to work around this restrictions? Which other SDR support this feature?
BladeRF maybe?
