blindscan under GNU/Linux
Posted: Mon May 14, 2012 11:31 pmhello list,
I tried to have a blindscan with the 6925 under GNU/Linux. The only reference I found is this link:
viewtopic.php?f=22&t=110&start=100#p4560
I did a simple script, using szap-s2 to connect on the frequency. For that you need to create a dummy channel.conf such as:
test:12345:h:0:0:1:1:1
test:12345:v:0:0:1:1:1
where 12345 = frequency, h or v to check both polarization, 0 for adapter 0 and 0 for symbol rate (it should be found by the frontend). For PID, etc. just put the value 1, which means 1:1:1.
Then i simply check for a frequency using (for H and V polarization):
szap-s2 -c ./channel.conf -n 1 -x
szap-s2 -c ./channel.conf -n 2 -x
if I receive a FE_HAS_LOCK, (grep) I execute the command
dvbsnoop -s feinfo
to obtain the symbol rate.
However, szap-s2 by default executes 10 tests before quitting if nothing is received.
Obviously you can patch it to accept only 3 tests, but that's a bit "hacky"
The bad point is that szap-s2 is unstable, if you check for many frequencies without a lock. Indeed, he is not able to detect existing signals.
My hack is to connect on an existing frequency between two guess, but it does not work perfectly. At the end, I have the most ridiculous blindscan speed with the most efficient card.
So here is my question: is there a real blindscan tool for this product under GNU/Linux or, like the TBS 5925, the TB2 6925 must be considered as "MICROSOFT WINDOWS ONLY" products ?
To be honest I'm totally disappointed by the GNU/Linux support and I really regret to not have bought a PRO8000, which works under Linux
