Send message to a Pager

[Virtex7]

this is kind of a fature request, because there should be all nessessary pieces of software to send a message to a pager.
i have tried to send to a motorola advisor, but the pager will not recorgnise the message. i have checked the frequency with an rtl_sdr and can demodulate with multimon_ng and the same rtl_sdr. so i think there is only a very small problem, i can't find.

could you tell me if and if yes how i have to send a message to the pager so it will display it.

Thanks,
Philipp

Hello Philipp,

As I do not have that pager, I cannot really comment on it. I propose you can try with messages of small size or try different opties to see if you can get something out of it.

BTW. I did see that the motorola advisor exists in both POCSAG and FLEX version. Do doublecheck that you have a pager for the POCSAG protocol and not FLEX.

Cheerio!

Hi,

I am sorry but It looks like I closed the ticket by accident. Feel free to open a new issue if you think that your issue is not solved.

Looking at setting this up and just wondering if anyone has actually been able to send messages to a pager.

[Virtex7]

unfortunatelly not me, but sending an identical looking message at the right frequency tu netmon_ng works for me. the reason the pager does not respond is a myth to me.
but try, the hardware is cheap.

My radios are arriving the next couple weeks. I'll give it a shot with a couple Apollo pagers. If I can't get it going maybe I can send Kristoff some hardware to test on.

Not at the moment. I've UHF pagers on 1200 baud, but this script (for now)
only allows 512 baud. My 512 baud pagers are VHF, but the transmitter can't
go down so far...

I've tried to tweak the library to do 1200 baud, which seems to happen, but
then the preamble is too short (and the pager won't be able to sync). I've
stopped this project to switch to the Arduino POCSAG encoder of Henry Carl
Ott N2RVQ. Using a terminal application or any other script to send a
string to the serial port you can send POCSAG 512, 1200 and 2400 baud,
inverted and non-inverted.

There is some info on our page dutchamateurpagernetwork.nl. For now only in
dutch, but:

• Google translate will help you
• I'll be available for info too!

And see an example of 512 baud here --> http://youtu.be/0C_wt83kXFA

mhohman, Ronald, virtex,

The 1200 and 2400 bps version has been been tested by Mike (the author of the radiohead library) and it did work for him.

I did my development of the code with a real pager but also using a RTL-donglew ith rtl_fm and multimon_ng as troubleshooting tool.
That is usually the best way to determine if the message that is being broadcasts is correct or not.

Anycase, feel free to clone the project and change the code as needed. That's why tools like github exist in the first place:-)

Good to hear Kristoff!

I'll give it a try as soon as I can free up some time.

Thanks for the info!
