AW: gpsd and as-needed patches
by Andreas.Eversberg 21 Jul '11

21 Jul '11

hi vlatko, thanx for your patches. i don't have knowledge about gpsd api. before i can apply them, i need to know about gps_waiting() function. the osmo_gpsd_cb() function in common/gps.c is called when there is data to be read from gpsd. this function (like any other function) may not delay or block. (except for the CPU processing time of the function.) if no data is available from gpsd, the function must continue with "goto gps_not_ready;" immidately. what will gps_waiting() do in case there is no (complete) information available? regards, andreas

gpsd and as-needed patches
by Vlatko Kosturjak 20 Jul '11

20 Jul '11

Hello! Hopefully this is right place to send patches since I don't have access to tracker. I'm sending two patches against latest git version. First one is updating gpsd support since new gpsd have few functions changed: I've #ifdefed each offending function, so you can check each function in configure process or just wrap everything inside same #ifdef, depending on your wish. I have #defined timeout, but it can be done as variable if you think 2000 miliseconds is not good for everybody. Other patch is just quick hack to support --as-needed linker flag, so osmocombb can compile fine on distros which enforce such flag. In order, to read more about flag, read here: http://www.gentoo.org/proj/en/qa/asneeded.xml (In short, order of flags do matter) Hope it helps, -- Vlatko Kosturjak - KoSt

Motorola C116 experiment
by Henk 18 Jul '11

18 Jul '11

Hi, I could not resist buying a C116 for 15 euro, so I compiled osmocombb and connected a 3.3V serial cable. Of course the C116 was not in the supported list, but I was hoping it would work as it seems that it is very similar to the C115. Here is my load attempt: (used -m c123 ) but there's no loading of the image. I am not using TX mode, also I don't have a SIM installed. Anything I can try to get it working? ./osmocon -p /dev/ttyS0 -m c123xor ../../target/firmware/board/compal_e88/loader.compalram.bin got 1 bytes from modem, data looks like: 00 . got 2 bytes from modem, data looks like: 00 81 .. got 4 bytes from modem, data looks like: 1b f6 02 00 .... got 1 bytes from modem, data looks like: 41 A got 1 bytes from modem, data looks like: 01 . got 1 bytes from modem, data looks like: 40 @ Received PROMPT1 from phone, responding with CMD read_file(../../target/firmware/board/compal_e88/loader.compalram.bin): file_size=16788, hdr_len=4, dnload_le n=16795 got 1 bytes from modem, data looks like: 66 f got 1 bytes from modem, data looks like: 74 t got 1 bytes from modem, data looks like: 6d m got 1 bytes from modem, data looks like: 74 t got 1 bytes from modem, data looks like: 6f o got 1 bytes from modem, data looks like: 6f o got 1 bytes from modem, data looks like: 6c l Received FTMTOOL from phone, ramloader has aborted got 1 bytes from modem, data looks like: 65 e got 1 bytes from modem, data looks like: 72 r got 1 bytes from modem, data looks like: 72 r got 1 bytes from modem, data looks like: 6f o got 1 bytes from modem, data looks like: 72 r got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: 1b . got 1 bytes from modem, data looks like: 66 f got 1 bytes from modem, data looks like: 6d m got 1 bytes from modem, data looks like: 74 t got 1 bytes from modem, data looks like: 6f o Regards, Henk

USB -FTDI 232RL- RS232 Converter
by iBruno 16 Jul '11

16 Jul '11

Hello I am having troubles, to find the decent cable/interface to get this working properly!! I bough converter USB -FTDI 232RLChip- RS232, Converter. IS giving me 6.60v Output.. and I needed 3.3v. Electronically, what can I do, to adjust for the correct Voltage? My phone didn't fry, besides I got connection! when I load the hello world or layer one, is not completing the task! I believe is because of the amount of power. If you know a cable that works decently, let me know :-) Big thanks to whole community.

GSM 03.22 bug / unreachable code?

Hi Andreas, while using Smatch on layer23, I discovered a potential problem in GSM 03.22: There is a loop with an if-statement, and there might be missing curly braces. Do you think this is the correct way to fix it? diff --git a/src/host/layer23/src/mobile/gsm322.c b/src/host/layer23/src/mobile/gsm322.c index 210215e..766ffbf 100644 --- a/src/host/layer23/src/mobile/gsm322.c +++ b/src/host/layer23/src/mobile/gsm322.c @@ -983,9 +983,10 @@ static int gsm322_a_user_resel(struct osmocom_ms *ms, struct msgb *msg) /* search current PLMN in list */ llist_for_each_entry(plmn_entry, &plmn->sorted_plmn, entry) { if (plmn_entry->mcc == plmn->mcc - && plmn_entry->mnc == plmn->mnc) + && plmn_entry->mnc == plmn->mnc) { plmn_found = plmn_entry; break; + } } /* abort if list is empty */ -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

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? Cheers, Li -- View this message in context: http://baseband-devel.722152.n3.nabble.com/problems-to-run-mobile-app-tp316… Sent from the baseband-devel mailing list archive at Nabble.com.
