Is data actually sent if "COMPILED WITHOUT TX SUPPORT"?
by Sergey 08 Jul '11

08 Jul '11

Hello! Is any way that data is actually sent to air if on loading "layer1.compalram.bin" 'osmocon' says: "THIS FIRMWARE WAS COMPILED WITHOUT TX SUPPORT!!! " ? E.g. when 'mobile' says "sending page response" does it really communicate with the BTS? I'm talking about main branch (not testing) and compiled without TX support. Sorry if it's obvious, I just dont want to find "the very extent permittable by law".

gsm specifications
by Sergey 06 Jul '11

06 Jul '11

Hello, everyone! I've got c123-compatible phone, the firmware is running and that's really cool. Testing branch even sometimes says that a call has been released, but it doesn't seem to reach the target (no ringing). I would like to debug and maybe contribute, but... But here is a problem: I don't understand GSM and can't find reasonable documents to read. I've looked through a book on gsm "GSM and Personal Communications Handbook", but it doesn't seem to provide enough info. Specifications of GSM I found at http://www.3gpp.org/specification-numbering are too plentiful. Could you please advise some books to understand the protocols? Or could you tell me where to look for specifications and which should be read first (an what to be read at all) ?

GPSD support
by Victor P 06 Jul '11

06 Jul '11

Hello.I have been trying to use cell_log with bluetooth GPS. I used gpsd v 2.37 and v 2.95, but in both cases I had the error "Osmocom was compiled without gpsd support". Should I use another version of gpsd or mistake in compilation (any patch?)? thank you for helpWith best wishes,Victor

Success at last - C139 now working Layer1.bin displayed on phone :)
by Raz Sharif 05 Jul '11

05 Jul '11

Dear all, the last few days I have as you know sent a few mails in my quest to delve into the Osmocomm GSM stack. A few problems later and a few substitutes later such as a C139 phone versus the C115 am I now good to go it would appear. Please see below. I did a lot of RTFM and would also like to to thank the folks who provided me with pointers. I will no doubt have a few more issues so lets see. In summary - The Prolific cable works fine albeit a small cut back on the connector - 2.5mm side C115 is supported but if you can go for the C139 - Too many issues to resolve with C115 maybe due to a specific Firmware variant. If you have the time to hack around I am sure it not difficult to work. Here's my Boot loader dump. Please see below. Thanks Raz http://pastebin.com/A1xf8Wkt

Osmocom Loading Issues - TTYUSB0 loopback
by Raz Sharif 04 Jul '11

04 Jul '11

Hi folks, further to my previous email i now ran : I simply pressed the Power Switch a few times but not power on. This is what is recorded. As you will recall i get the FMTool Error and aborted message and never see Prompt2. With no Osmocom programs running can someone please confirm that this output is correct or indeed suggests that the Phones Serial Line or other Firmware or Phone Hardware is causing this error please - would be grateful.

osmocn question
by eisencah eisenach 04 Jul '11

04 Jul '11

Hi everyone. One remark regarding osmocon : it seems to me that we're reading one byte at the time from the serial port once we're done with downloading code into RAM. That seems quite on overhead (specially on slow machines like mine). I believe we should modify that once dnload.expect_hdlc == 0 we can free up the entire buffer. Is that so or I'm missing something? Mihai.

Fwd: Please can anyone advise me - FMTOOL Error and no further processing
by Sébastien Lorquet 04 Jul '11

04 Jul '11

Please do not use reply in gmail, but reply to all instead. Otherwise you will only write to the message's author, Sebastien ---------- Forwarded message ---------- From: Raz Sharif <issertiv(a)gmail.com> Date: Sun, Jul 3, 2011 at 9:34 PM Subject: Re: Please can anyone advise me - FMTOOL Error and no further processing To: Sébastien Lorquet <squalyl(a)gmail.com> Sorry yes i did post this message before in an attempt to get some better insight in to the issues. The loopback test i shorted the inside and outermost pins and echo of characters appeared. I think cable is ok. Its a prolific usb to serial. I do not have a serial connector so cannot try the FTD cable option. All software looks ok but the Osmocon.just hangs and FMT tool error. So i am a little stuck to be honest. Sorry for sending this twice. Thanks Raz On 3 Jul 2011 19:29, "Sébastien Lorquet" <squalyl(a)gmail.com> wrote:
