[srslte-users] DL stream in srsUE

[Andre Puschmann]

Hey Mathias,

depending on what kind of post-processing you are planning to do, there
are multiple points at which you may grab samples from the flow-graph.
If you are after synchronized sub-frames, then
srslte_ue_sync_get_buffer() is what you are looking for. Just write the
buffer that the function returns to a file.

Btw. please turn off HTML postings in your mail client of choice. I just
stumbled across this post by chance as it was sorted out as spam.

Thanks
Andre
