Cannot tune DVB-S2 nor szap

[CKDewey]

I can tune DVB-S but not S2 under tvheadend with the latest drivers from your web site using Ubuntu server 10.10 amd64 with kernel 2.6.35-22.

I've disabled tvheadend at boot but I still cannot scan using szap-s2 at all.

I'm pointed to Palapa-D at 113E.

Here is my szap config:

Code: Select All Code

SPC:4080:h:0:28125:515:653:4
ALJ:4100:v:0:30000:4466:4467:19

My command:

Code: Select All Code

sudo ./szap-s2 -c spacetoon.data -a 1 -p -r -S 0 -M 2 -C 34 "SPC"

and the output:

Code: Select All Code

sudo ./szap-s2 -c spacetoon.data -a 1 -p -r -S 0 -M 2 -C 34 "SPC"
reading channels from file 'spacetoon.data'
zapping to 1 'SPC':
delivery DVB-S, modulation QPSK
sat 0, frequency 4080 MHz H, symbolrate 28125000, coderate 3/4, rolloff 0.35
vpid 0x0203, apid 0x028d, sid 0x0004
using '/dev/dvb/adapter1/frontend0' and '/dev/dvb/adapter1/demux0'
FE_SET_PROPERTY failed: Invalid argument

It hangs at this point, and I must ctrl-C to exit. I get the same result with 'ALJ' which is S2.

In tvheadend I can tune and play the first program, but the mux for the second program shows no signal. Both work fine on my set-top box.

I've also tried the w_scan utility and get 'no signal.' Your help is greatly appreciated.

Regards,

Now when I try to build the drivers under the latest Ubuntu 10.10 generic kernel (2.6.35-25-generic) I get:

Code: Select All Code

Hi Cody,
I did not see your email, can you post the reply here?

Thanks,

hi, of course, maybe, you're no the same customer, but asking similar question(s), here is what i replied:

please, give me 'szap-s2' command line and output that you use when you try
to lock those DVB-S2 transponders. also, one mistake that i see right away
is that you use 'szap-s2' without "-l" (lower case "L") switch to tell your
LNB type to 'szap-s2' and that's why you get error:

> FE_SET_PROPERTY failed: Invalid argument
> couldn't find pmt-pid for sid 18b53

in fact the lock you got with 'szap-s2' is not acquired by 'szap-s2',
because of the above error, but some lock left from previous use of the card. if
you type 'dmesg | grep tbs6981fe' and/or check other debug messages with
'dmesg', i'm sure there will be error message that the frequency is out of
range. anyway, let's first check the output of 'szap-s2' when you try to
lock those DVB-S2 transponders and then proceed from there.

thank you,

Hi Cody,

My szap config file looks like this:

Code: Select All Code

SPC:4080:h:0:28125:515:653:4
ASN:4100:v:0:30000:4466:4467:19


Here is what I get with the 'S' transponder when I add the '-l' command:

Code: Select All Code

videobox@videobox:~/linux-s2api-tbs6980-1_20101024/szap-s2$ ./szap-s2 -x -c spacetoon.data -l 5150,5150 -a 1 -p -r -S 0 -M 2 -C 34 "SPC"
reading channels from file 'spacetoon.data'
zapping to 1 'SPC':
delivery DVB-S, modulation QPSK
sat 0, frequency 4080 MHz H, symbolrate 28125000, coderate 3/4, rolloff 0.35
vpid 0x0203, apid 0x028d, sid 0x0004

status 1f | signal bf2e | snr 8888 | ber 00000000 | unc 00000000 | FE_HAS_LOCK


However the 'S2' transponder on the same satellite does not work, it just hangs. The feed works fine on my set top box:

Code: Select All Code

videobox@videobox:~/linux-s2api-tbs6980-1_20101024/szap-s2$ ./szap-s2 -x -c spacetoon.data -l 5150,5150 -a 1 -p -r -S 1 -M 5 -C 56 "ASN"
reading channels from file 'spacetoon.data'
zapping to 2 'ASN':
delivery DVB-S2, modulation 8PSK
sat 0, frequency 4100 MHz V, symbolrate 30000000, coderate 5/6, rolloff 0.35
vpid 0x1172, apid 0x1173, sid 0x0013
using '/dev/dvb/adapter1/frontend0' and '/dev/dvb/adapter1/demux0'


I hope you can advise further on how I might get this working.

Thanks,

CK

Cody,

Can you tell me which Linux distribution is known to work with your drivers? I have been using Ubuntu for years but I will happily re-install with Debian or any other in order to solve the problem quickly.


Thanks,

hi, our Linux development and testing is done exactly in Ubuntu. we saw you mailed us and let's sone some live debugging of the problem as you suggested. we're going to contact you via Skype.
