The main problem I have is I am a pure HW design engineer and my knowledge of Linux, Python and high level SW is not very strong, but I am learning.<br><br>Best regards,<br>Farhad<br><div style="font-family: arial,helvetica,sans-serif; font-size: 13px;"><font face="Tahoma" size="2"><hr size="1"><b><span style="font-weight: bold;">From:</span></b> Sylvain Munaut <246tnt@gmail.com><br><b><span style="font-weight:

All the<br>phy/mac levels are no trivial and will need state processing and such<br>... not something I really see in GR.<br><br>Using fifo on the filesystem you can pipe directly/live the flow of<br>info from GR outpout to the tetra-rx input.<br><br>Cheers,<br><br>
