neighbour cell measurement
by Andreas.Eversberg 15 Jul '11

15 Jul '11

hi, i would like to commit my well tested neighbour cell measurement code, as well as the improved cell selection / re-selection process soon. with it, it is possible to move with the mobile phone while beeing in idle mode (no call). it tracks neighbour cells and switches if a better cell is detected. i found and fixed many bug issues in mobility management and cell selection process. i did allot of driving tests. in order to do that, the neighbour cell measurement code for layer1 is required. this code must be reviewed first. i splitted it in three patches: neigh_getset.patch [layer1] Adding rffe_set_gain() and rffe_get_gain() to get/set computed gain. rffe_compute_gain() is the new name for rffe_set_gain(). I needed to change this, to solve the name collision with the rffe_set_gain() function, which actually sets the absolute gain. rffe_get_gain() will now read the absolute gain which has been computed by rffe_compute_gain() or set by rffe_set_gain(). neigh_l23.patch [layer23] Adding neighbour cell measurement to L1CTL interface. (layer23) neigh_l1.patch [layer1] Adding neighbour cell measurement code to layer1. When listening to BCCH, layer1 may measure the power level of neighbour cells. A list of neighbour cell frequencies need to be sent to layer1. After the measurement is done, the results are indicated to layer23. andreas

problems to run ./mobile app
by josephli 15 Jul '11

15 Jul '11

Hello every: When I tried to run ./mobile -i 127.0.0.1, the words Failed to parse the config file: '/root/.osmocom/bb/mobile.cfg' Please check or create config file using:'touch /root/osmocom/bb/mobile.cfg' came out. I checked my directory /ect and there is nothing there. It seems that network between my PC and phone is block so that the application ./mobile can not communicate with phone. However the layer1 can load on the phone and work properly. Can any one tell my how to fix this problem?

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) ?

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
