NO Signal with PCTV DVB-S2 Stick

Post by mjoogoo »

I'm experimenting with the minisatip, but I have the issue that the scan does not find services (no signal)
I build the minisatip 0.5.58 on ubuntu 16.04 server with no issues.
I have a pctv DVB-S2 USB tuner. The tuner has been tested with different Sw and I verified that there is signal on the cable (Astra 28.2)
As a Client I use Elgato Sat>IP client on Android.
The issue is that I do not manage to get any services captured by the scan.
I attach a full verbose log
Any advice is welcome

Francesco

Hi,
this is what I see everywhere minisatip is trying to tune:

[31/08 17:05:46.809 main]: send_diseqc: FE_SET_TONE failed for fd 7: Bad address
[31/08 17:05:46.861 main]: send_diseqc: FE_DISEQC_SEND_MASTER_CMD committed failed for fd 7: Bad address
[31/08 17:05:46.946 main]: send_diseqc: FE_DISEQC_SEND_BURST failed for fd 7: Bad address
[31/08 17:05:46.961 main]: send_diseqc: FE_SET_TONE failed for fd 7: Bad address

When you say different software you mean on Linux (same OS as where you run minisatip) ?

Because this makes me thing it might be a driver issue.

Hi Cata,
No when I mention different Sw, I mean a a different program executed on a different OS, Windows.
In relation to the Driver, I can see the device when I give the command lsusb:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 046d:c31c Logitech, Inc. Keyboard K120

Just to give some more details:
the Usb tuner is directly connected to the LNB, no DISEQ devices in between t support multiple dishes,

Problem Solved.
The issue was that I was missing a firmware file specific for the 460E.
The funny thing is that the firmware controls only some specific functionalities (as DISEQC), but the device itself was recognized OK by Linux and by the minisatip.
Thanks Anyway for the quick reply.
The MiniSatIP software look to work well and is quick in the channel change, very low load of the processor.
I'll provide updates on my test.
