Hi,

New version on the feeds!


1. dab-cmdline-sdgradio command will now be used from on.

The code can be found here: https://github.com/satdreamgr/dab-cmdline

New version supports changing to specific channel by writing the hex sid of the channel to stdin. Writing a newline on stdin it switches to next program.
New version also will report much more information to output, eg SNR. We need to see the output in order to add SNR support in UI.

2. The SDGRadio updated to make use of the new command

Also sdgradio updated to support creating list of channels, by pressing menu a list of available channels names will be appeared.
The log will contain the last 200 entries and no duplicates.
The frequency was increased to display 2 decimal digits .


The recipes for building SDRadio for other systems are available here: https://github.com/satdreamgr/SDGRadio

Please report if new features work. Also provide output from logs, we need to see how SNR get's written.


PS. @matrix.

Use this https://a.uguu.se/xy7Lnf3ENepA_dab-c...v7ahf-neon.ipk

I do not have BH build environment, since recipes are available many somebody build them against BH?

i have error/E2 crash with Menu button >>> unexpected keyword argument 'windowTitle'

========================================================
The frequency was increased to display 2 decimal digits

I think is better to use 3 digits because that's the real frequency.

Testing Continu

[Matrix10]

I have changed this line removed 'windowTitle

self.session.openWithCallback(self.programAction, ChoiceBox, title=_("Select Radio Program"), list=self.programs)

I have now program list

I had to change also cmd = "dab-rtlsdr-sdgradio -C %s -W50

Test wil continu

[Matrix10]

I have change again parameter W to 100

This parameter W must be tested
now the speed is much higher at the first start / scan
But if the parameter is small then it works unstable and finds nothing or driver crash .



After my changes par W and bug fix with choise list.
All is working speed is much faster .
Channel change from the list working perfect after i have fixed this error (using Open Black Hole - OE-A image)

Hi,


I increased the timeout from 15 seconds to 30 seconds! Going to 100 is almost 2 minutes!

I think it's completely wrong to wait 2 minutes in order to scan channels, maybe dab-cmdline author should be informed, there might be something wrong (that makes slow scan).

Here are the last changes: https://github.com/satdreamgr/SDGRad...c25e51efb0d30c

Build is running an online update will automatically bring the last SDGRadio changes.

Thanks @matrix10 for your feedback, I think DAB now is truth in Enigma2 :)

Hi,

I have make some test yesterday.
I need to make 15 or 20 scans to find the data.
During the scan the snr is in the range of 1 to 9.
When the data are found the snr is 10 or 11, in this case the channel change work fine and no lost of sound.

I'll made other test today with last update, thanks for this new one and sorry for my poor english!

Off topic, I can't post any OSD sceenshot (with webif "hiht résolution" or grab) because the quality is very poor with the octagon SF4008 & Experimental SatdreamGR image.

@athoik

I have made some skin modifications for better support (color all images definitions )
added Menu button
changed size for <widget name="radiotext" informations e.t.c

I do not feel that parameter W extends much
I have sometimes a channel almost directly
and sometimes I have to wait.
I do not know what effect speed.
Maybe the strength of the signal or the information in the ether.

[Matrix10]

Another thing I notice
is that I sometimes have only a few channels in the list
and sometimes ten or more
