GNU Radio QPSK burst packet from a binary file

I am struggling trying to implement a packet burst. My data are in a binary file. What I want to do is to send my data in the flow N times per seconds, let's say 2, to simulate a burst transmission.

The "Message Strobe block" seems to be a good candidate but I don't understand how to use it.

Here the (uncorrect) flow I want to have in my transmitter side: enter image description here

I tried to get insight from Simple GNU Radio Eventstream Based Burst Extraction and Plotting and Burst Transmission in GNU Radio Sample Streams with Eventstream without success :(

Thank you a lot

Solution

  • I used the message strobe block and I build my own block to read a file, build a pmt message and output it directly as a new pdu. It seems to work perfectly well that way :)
