Hello, Fonts and a LCDgui (plain text)

Hello OsmocomBB list members, To shortly introduce myself, i am a sysadmin with much spare time and a Motorola C115 mobile phone. I came to this place after watching a recording of the OsmocomBB talk at the 27c3. That really started my interest on opensource GSM. After reading the wikipages and the mailing list archives i downloaded the sources and had a fully compiling OsmocomBB setup within a few hours. Great work! After slaying some headphonecables and an usbcable i hooked my c115 onto the serialport of my pc and it booted out of the box! Since i am neither a programmer nor an electronic engineer i thought about what i could be interested in doing that contrbiutes to OsmocomBB. (Learning a little C has not hurt too many people i think. so i am on it.) I didnt find it at http://bb.osmocom.org/trac/wiki/AreasOfWork but in the Mailinglistarchives of April-2010 i stumbled upon Christian Vogels post "Subject: PATCH: 5x8 font". After some manual patching i made it to compile the demo app (Printing all available characters in the font from upper left corner down to the bottom. Now that looked allmost like a phone :) It seems like there have not been any follow ups on proportional fonts and the remaining ascii characters as well as the possibility to view different sizes of fonts on the screen. Because there is not much to see on the C115 and there is no navigationsystem of any kind implemented in the compal_e88 firmware I typed together a ericsson clone menu structure with a total of 330 menuitems (transations english to german allmost finished) to have something to display once the proportional 5x8 fonts are finished. now i would continue to write a menu action handler that checks if a navigation key is pressed if a entry in the menu is selected lets look if there is a PhoneMenu "muid" with the siblings "suid" the menu is drawn. if it is a sibling only a switch case list where all actions get caught and processed will handle it. Well, what do you think about that? Should it be built in another way? Am i to early in typing menue structures while the whole "rendering" is not sorted out in any way? Does anyone work on the fonts or a UI? I really am not able judge whether a nested structure monster like this really is the right solution. What it definitly is it is easy to read understand and extend. at least for me ;) if someone wants it i can post the complete menu (~1200 lines) somewhere. Best wishes, Rade Below are some snipplets of the things i allready did: ...sniplets... struct PhoneMenu { &nbspint muid; /* menu uid */ &nbspconst char* menuLabel_en; /* menu name, english */ &nbspconst char* menuLabel_de; /* menu name, german */ &nbspchar siblings; /* amount of siblings within the menu */ &nbspstruct PhoneMenuSibling pms[]; /* nested structure below */ }; struct PhoneMenuSibling { &nbspint suid; /* sibling uid */ &nbspconst char* siblingLabel_en; /* label in english */ &nbspconst char* siblingLabel_de; /* label in german */ }; .... A Menu looks like this: struct PhoneMenu menu = /* the startscreen */ { 0, "Main Menu", /* menu label */ "HauptmenÃ¼", /* menu label in german language */ 6, /* 6 items in the list below */ { {1, "Phonebook", "Telefonbuch"}, {2, "Messages", "Nachrichten"}, {3, "Call information", "Anrufinformation"}, {4, "Active call", "Aktive Verbindung"}, {5, "Settings", "Einstellungen"}, {6, "Extras", "Extras"} } }; struct PhoneMenu menu_phone_book = { 1, "Phone book", "Telefonbuch", 10, { {11, "Call Contact", "Kontak Anrufen"}, {12, "Add Contact", "Kontakt hinzufÃ¼gen"}, {13, "Edit Contact", "Kontakte bearbeiten"}, {14, "Business Cards", "Visitenkarten"}, {15, "Call from SIM", "Adresse aus SIM"}, {16, "Groups", "Gruppen"}, {17, "Calling Cards", "Rufkarten"}, {18, "Options", "Optionen"}, {19, "Memory status", "Speicherverbrauch"} {10, "Special numbers", "Spezialnummern"} } }; ....... struct PhoneMenu menu_phone_book_business_cards_receive = { 143, "Receive", "empfange Visitenkarte", 2, { {1431, "Via Infrared", "via Infrarot"}, {1432, "Via Bluetooth", "via Bluetooth"} } };

Re: Emergency number
by Bogdan Alecu 07 Feb '11

>Do you run your own network? How do you plan to test your modifications? No, I'm not running my own network. I tried to make an emergency call and I got a voice saying to call to different numbers (police, fire dept, etc). That's why I need to know exactly what number is dialed from Osmocom and where I can modify it. I looked on the code but couldn't find (maybe I'm too tired).

thinking about the sim
by Sébastien Lorquet 07 Feb '11

07 Feb '11

Hello, I was walking through trac while I came across this file: http://bb.osmocom.org/trac/browser/src/host/layer23/src/common/sim.c I see here: 183 /* send APDU to card reader */ 184 static int sim_apdu_send(struct osmocom_ms *ms, uint8_t *data, uint16_t length) 185 { 186 LOGP(DSIM, LOGL_INFO, "sending APDU (class 0x%02x, ins 0x%02x)\n", 187 data[0], data[1]); 188 l1ctl_tx_sim_req(ms, data, length); 189 return 0; 190 } ohoh, that's hardcoded. If we would like to have a software SIM, a SIM in a card reader on the PC, or a real sim in the MS, I think this would this be the correct place to plug a modular sim implementation. I mean something that looks like: struct osmocom_sim_ops { int (*sim_apdu_init)(.....); int (*sim_apdu_fini)(.....); void (*sim_op_reset)(.....); void (*sim_apdu_send)(.....); void (*sim_response_callback)(.....); }; void ms_register_sim_driver(struct osmocom_ms *ms, struct osmocom_sim_ops *ops); this could be a part of struct osmocom_ms. I would be easy to have 3 implementations: -sim in the mobile, using the current calls 'l1ctl_tx_sim_req' 'l1ctl_tx_sim_conf' -sim in PCSC using pcsclite or winscard, and a command-line option to select the reader (by index, by name, or first reader with a card inside for simple setups) -virtual sim using pure software What do you think about this? Regards Sebastien

Hello, What number is it dialed when I place the emergency call? Maybe you could also point me to where I find that number as I want to modify it. Thanks. Regards, Bogdan

Re: GsmMap without GPS
by Bogdan Alecu 07 Feb '11

07 Feb '11

Hi all, Harald - I will put the sourcecode later on today. The reason I didn't was because the code it's not so clean and good - but it works. Martynas - my phone remain stationary and in fact I have over 40 cells (from other networks too). I don't find it to be a lot. About the precision, Google returned "accuracy":3875.0" which is surprisingly true. I was about 3-4km away from the final coordinates. Maybe I'll modify the code to give the position for each cell it finds. Tomas - No proprietary libraries, the code will be here in the evening. It's not so professional done, but considering that it took me somewhere around 30 minutes, I'm good with it. Regards, Bogdan

GsmMap without GPS
by Bogdan Alecu 06 Feb '11

06 Feb '11

As I said in a previous post, I don't see why I need to have a GPS to get an approximation of my location. I then suggested using an open source cell list or Google API. So, I have just finished writing a program that parses your kml file from the gsmmap, send the request to Google and it will get your approx location (just like Google Maps on your mobile) and write the result in another kml file. The program is written in Java. To run it under windows: C:\Program Files\Java\jdk1.6.0_17\bin>java -jar glocation.jar Usage: glocation -i <path to input file> -o <output file> C:\Program Files\Java\jdk1.6.0_17\bin>java -jar glocation.jar -i c:\gsm.kml -o final.kml Name : MNC 03 (T-Mobile) Name : LAC 3030 Name : CELL-ID 0031 Name : CELL-ID 0032 Name : CELL-ID 135c Name : CELL-ID 24a7 Name : CELL-ID 4c2a Name : CELL-ID 4c31 Name : CELL-ID 4d10 Name : CELL-ID 51e3 Name : CELL-ID 537b Name : CELL-ID 5567 Name : CELL-ID 5f8a Name : LAC 4010 Name : CELL-ID 4c34 Name : CELL-ID 5b4b --------------------------------------- Sending data to Google... {"location":{"latitude":48.21451,"longitude":16.356414,"accuracy":511.0},"access _token":"2:BaEsaRey871FCt1e:A5vJ-lyJuPrukpMV"} lat=48.21451 long=16.356414

Re: Non Standard Baud Rates?
by MATTHEW EVANS 04 Feb '11

04 Feb '11

*bump* Anyone have any thoughts / advice on this? Many Thanks, Matt. ----- Original Message ---- From: MATTHEW EVANS <mattjevans(a)btinternet.com> To: baseband-devel(a)lists.osmocom.org Sent: Friday, 21 January, 2011 21:08:36 Subject: Non Standard Baud Rates? Hi, I'm trying to get the burst_ind branch working at the higher speed baud rates. I have a USB to Serial FTDI Cable (FT232R) plus the T191. This setup works fine with the main trunk of osmocombb. When I fire up osmocon, layer1 appears to download to the phone and runs successfully. Osmocon then logs 'Received DOWNLOAD ACK from phone, your code is running now!'. The phone has layer1.bin displayed as usual. However it goes no further and just hangs. Could anyone please give any advice on what to try next? Thanks, Matt.
