[Discuss-gnuradio] USRP1 Inband firmware questions

[Sylvain Munaut]

Hi,

I'm trying to adapt openbts to the inband firmware for which the source
are available. (it seems the sources for the std_inband.rbf that openbts
uses has been 'lost')

Two things I'm faced with

 - How can I know the 'current' TX timestamp ? I want to send a ping
command, but I don't see a way to know what timestamp I should use.

 - The timestamp seems imprecise: I often get a timestamp difference
between two packets of 24191 or 24193  while I should in fact get 24192
(I'm at 192 decimation). With such a high decimator, I can fix it up
myself, but still, that looks weird.


Cheers,

   Sylvain
