I do not want to see the modulation type with the analyzer... al I want to get is a frequency (and an indication of the symbol rate) to finally tunein...

It would be nice to have a way to get a cheap spectrum analyzer on E2 with help from a blindscan tuner... But we cannot make it as we depend on the box manufacturers for a binary or (better) driver support... (and also for blindscan as it is now I would prefer driver support based on some kind of standard...  A spectrum analyzer feature is a nice to have in addition... (I think more usefull than blandscan is today).

@Huevos, @OpenPLi

 

Do you know if the blindscan binaries make use something like "ioctl" that is easy to reveal data using strace?

 

Or maybe we can use something like LD_PRELOAD to "steal" the data passed to receiver?

 

Then it might be possible to write a "free" blindscan binary or better to integrate directly on enigma2!

 

Or they might using encryption+ptrace detection etc etc to stop people from learning blindscan secrets...?

[littlesat]

That might indeed be possible.... but you need to perform a lot of reversed engineering... And in E2 you need a lot of if box X use io adresses A, when box Y use io adresses B etc... which is something you do not want...

To make this in a structered way you need to have them in the drivers.... controllable via e.g. procs... and then hopefully the same protocol is used between different boxes.... (but this might be an utopy)

[Erik Slagter]

With strace you might be able to reverse engineer the i2c commands (because that's the way it works, it completely bypasses enigma2, the linux kernel+dvb api AND the drivers).

 

I guess the i2c commands will actually be the same for the same tuner (on different manufacturer's receivers) but you'd still have to find out on what bus each tuner is, there may be even more than 1 tuner on each bus. Some manufacturers make it easy (see /proc/bus/nim_slots), other (like VU+) are very secretive about it.

Thanks Huevos, I will take care of it. May take a while though before it's finished.

It only has the py file...

[Huevos]

Erik, what else did you want?

[Erik Slagter]

The blindscan plugin we offer is in the 3rd party plugins, I realised only a few days ago. There is not yet a repository for it. So we need a complete e2openplugins implementation I'm afraid. The last time I tried to do so for someone, it cost me a whole lot of time to get it working, I am not really familiair with building of plugins... So I kindly ask for a complete repo-ready set of files (including Makefile.ac etc.).

Erik, can't you just clone the OE-A example and use the plugin.py file I posted.

[Erik Slagter]

I'll have a look.

[Erik Slagter]

Thx!

[Erik Slagter]

Wow, it's in. I can't guarantee it will work properly in our environment...

 

It had quite a bit of "feet in the earth" as we say here to get it included, mostly due to my inexperience in this area.

boxbranding is not in Pli

from boxbranding import getBoxType, getImageVersion, getImageBuild, getBrandOEM

[littlesat]

boxbranding sucks.... it should go in fact not on brand but on feature...

[Huevos]

That is because Erik hasn't used the PY from this thread. The PY in this thread works fine in OpenPLi. Dima did the mod for OpenPLi.

Yeah I screwed up finally, I totally forgot about this separate python file

 

I will apply it, thx.

[Huevos]

Erik can you post a link please.

[Erik Slagter]

This should be fixed now, thanks Huevos and dimitrij!

[Erik Slagter]

Erik can you post a link please.

What do you mean, a link to what?

[Huevos]

To the finished commit location.
