Hi guys, I'm using the Osmocom sink with a LimeSDR. I'm testing with a very simple flowgraph (attached): a cosine source's amplitude is toggled according to the state of a QT push button, thus getting a crude CW transmitter.
The problem I'm seeing is that there is a huge delay (about 5 seconds) between the moment I press the button to the moment that the RF goes out on the air. I think that the cause is that the LimeSDR takes around 5 seconds to start working, so the cosine source is holding back 5 seconds worth of samples until the Oscomocom sink starts consuming samples. If I split this flowgraph into two as follows: 1st) cosine -> throttle -> udp sink 2nd) upd source -> osmocom sink and I start the second flowgraph and then the first, then I get little delay, but this is a very ugly hack. Is there a good way to solve this issue? Regards, Dani.
