The problem is related to the channel scan.
blindscan_13E_14-04-2016_18-17-04.xml
Please see:

After scan any internal tuner  --> 2 channels found

Use manual scan, if set System_DVB_S2 --> scan tuner (sundtek sky tv ultimate 5) --> 2 channels found

It should not be.
This is a bug in the drivers.
It can be fixed?

Which satellite do you use with Blindscan?
Blindscan is currently set up for Astra 19.2 (and similar ones).
The blindscan will need some symbol rates pre-set (currently we have only hard-coded the ones which are common on Astra 19.2 / Thor5 / Hotbird )

The S2 Blindscan output for the nim sockets will be modified with the next update (however it's a bit unclear when the next one will be available since we have several updates and a new RTSP streamingserver upcoming)

try attached mediaclient file

put it to /opt/bin

Zitat
cd /opt/bin
chmod 777 mediaclient

I see it was only possible to support up to 9 tuners on a system for the blindscan, the 10th was truncated to 1 with the mediaclient blindscan command.

Another question...
Code:
Dear Sundtek,


Recently we added DVB API v5 statistics into Enigma2 (see: https://github.com/O...7cb9b043797834)

I've got a request from a user that since above commit dB/snr caclulation is broken for Sundtek DVB-T (III).

I guess that you are using DVB API v5 statistics!

Could you please fill DVB API v5 statistics properly?

Currently we need at least the following: DTV_STAT_SIGNAL_STRENGTH scaled as FE_SCALE_RELATIVE, DTV_STAT_CNR scaled as FE_SCALE_DECIBEL and FE_SCALE_RELATIVE

Example values:

DTV_STAT_SIGNAL_STRENGTH S: 59172 U: 59172 L: 1 Scale: FE_SCALE_RELATIVE
DTV_STAT_CNR S: 12453 U: 12453 L: 2 Scale: FE_SCALE_DECIBEL
DTV_STAT_CNR S: 51007 U: 51007 L: 2 Scale: FE_SCALE_RELATIVE

Please let me know of your thoughts.

Best Regards,
Athoik on behalf of OpenPLi team

for  DVB API v5
Sundtek DVB-T (III) snr always 99%
Sundtek DVB-S/S2 (IV) snr always 88-89%

My workaround has been removed recently:
https://github.com/OpenPLi/enigma2/commit/abaabfdad4f278cbcfcf7e4915d2a8e20486bfac
Code:
When either signalquality or signalqualitydb are nonzero, the driver
implements the DTV_STAT_CNR property.
And we have to trust the driver to report the correct values, no need to
make any exceptions.

Perhaps this commit was meant to force snr percentage to dB calculation
for Sundtek, but in that case a different, more generic fix should be
made to calculate dB values based on the FE_SCALE_RELATIVE value
reported by the DTV_STAT_CNR property.

About this question...
http://support.sundtek.com/index.php/topic,1833.msg17003.html#msg17003

You can make changes to the drivers.
Return the DTV_STAT_SIGNAL_STRENGTH / DTV_STAT_CNR value as zero.
Or at least add a key to start the driver DTV_STAT_SIGNAL_STRENGTH/ DTV_STAT_CNR S with zero.

Please help Traurig.
