Setting Sub-Ric #19

Open ghost opened 7 years ago

ghost commented 7 years ago

Hi, thanks for your work! Is there any chance to set the sub-ric of the message? My pager always shows sub D, but for my purposes it should be A... Thanks in advance.

Can you explain more what you mean, or perhaps provide some reference links explaining what 'sub-ric' and sub A and D means?

I believe this refers to a subaddressing feature that some European POCSAG pagers (or particularly German?) have. I've found references to it in various forums and pager specs. It's not covered in the references I saw (the ITU recommendation, etc.); but there are some programs out there that decode it (e.g. http://www.baycom.de/software/products/poc32/) -- I just haven't put in the time to see what they're doing yet.

Also, I don't have a pager that supports it, so even if I can figure out how it's encoded, testing will be difficult.

Right. Perhaps this text something to place in the README or associated with the setting somehow, to ensure the next persion wondering find a clue why it isn't implemented.

How can one tell if a pager support it?

Is it possible to change the functionsbits in line 50 to a variable that can be changed from the gnuradio?

This functionbit is the "Subric" Identifier in German POCSAG Networks.

Thx.
