Hi list,
It's my first time posting here, and I've just subscribed - so apologies
for totally wrecking archive threading.
I've just received a copy of the e-mail regarding the OT-290, thanks to
Andrew Back; and I'm wondering it's possible to discuss the feasibility of
implementing this functionality with Harald - since it doesn't seem to have
generated much interest from others, and I'm "fortunate" enough to live in
a small British town without EDGE coverage (which should make it easier to
test GPRS-related tracing functionality).
Although I'm unfamiliar with how things work in Osmocom, I've previously
worked on Wireshark dissectors for USB-encapsulated AT commands, and
various NFC/smartcard-related protocols (PN532, FeliCa and MiFare); and am
also familiar with Nokia's proprietary ISI baseband protocol, and parts of
ETSI's GSM/UMTS specifications - so this sort of stuff isn't totally alien
to me.
I'm also currently studying Computer Science as an undergraduate (at the
University of Bradford) - but I should be able to make time to work on this.
Thanks,
Tyson.

Hi Tyson,
thanks for your introduction and for your interest in this project.

Even in areas with EDGE coverage, the network will always fall back to
GPRS if you use a GPRS-only phone (like the OT-290). So the fact that
your town only has GPRS doesn't make a difference here.

Osmocom, I've previously

Cool, this sounds like a good set of skills to address this problem.

I guess time is the key aspect here. I would definitely want to make
sure that whoever gets a OT-290 for implementing the GSMTAP interfacing
code is likely to be able to complete the task before GPRS is phased out ;)
So I guess I will leave it up to Denis and you to figure out who might
have more of an interest and/or time in this.
Regards,
Harald

Hi list,
Hi, and sorry for the delay of
responding.
Although I'm unfamiliar with how things work in
Osmocom,
That doesn't seem a problem at all.
The goal is only to interface the trace phone with wireshark trough gsmtap.
I've previously
worked on Wireshark dissectors for USB-encapsulated AT commands, and
various NFC/smartcard-related protocols (PN532, FeliCa and MiFare);
I never worked
on wireshark but that seem a usefull skill.
and am also familiar with Nokia's proprietary ISI
baseband protocol,
good, I know a bit ISI too but not too much in detail(I was
involved in the
port of SHR and freesmartphone to the nokia n900).
That skill can help a lot too.
and parts of
ETSI's GSM/UMTS specifications - so this sort of stuff isn't totally alien

good.
I don't know which one of us has the higher chances to succeed, but since you
are willing to do it, and that you seem to have the required skills, and that
I can work on other things as well(for instance finish the port nuttx to the
calypso phones), I would say that you can take the phone assuming you really
work on it and I hope you'll succeed.
I wish you good luck.
Also Harald Welte said:
The majority of what those phones can do is now also
possible with
OsmocomBB.
And I've already two osmocomBB compatibles phone(the freerunner and
the c155).
Altough I did not yet analyze the GSM protocol yet apart looking briefly at my
own gsm packets without understanding the details, I'm still learning how the
GSM protocol(Um and Abis) work(I only know the big picture so far) with the
online slides of Joachim Göller.
I'll also try to find out about all the other features of osmocombb, to look if
they are really usefull for development in the GSM protocol,and how to use
them legally in Europe.
So far I was concentrated on nuttx and only tried some of the osmocombb
features recently(like the gsmtap/wireshark integration on the master branch).
