Thank you for the answer.
I forgot to say that my graph is connected to hardware (bladerf or limesdr) via osmocom block. This one give me the error that there is not enough data.
Is it possible to do with hardware attached to gnuradio? All examples are without hardware and don’t have the clock of the hardware.
Thank you

Hello everyone,
Builind a FSK tansiever, I would like to send burst data. All the fec and data maniupation are made with custom block working with message.
After formating everything, I convert my data to Stream with « PDU to tagged Stream » block and send it to «GFSK mod » block.
This last block needs to have a steam to work (as I understand ). My burst messages come randomly from an UDP port and with different time interval.
When Nothing is tansmit the gnuradio flowgraph stops saying it does not have enough data comming to « PDU to tagged stream» to work.
How can I avoid this problem ? should I send zero between data ? Is there a bloc to do this ?
Thank you
Sam
