...a never ending story: i have a working ftdi-ttl, but the cp2102-adapters (http://www.ebay.de/itm/USB-2-0-to-UART-TTL-6PIN-Module-Serial-Converter-CP2…) with the same cable dont work under ubuntu or windows. if i rub the top of the 2.55mm with my finger random data appears. but the loader doesnt upload the firmware. i used the txd, rxd and gnd pins and checked the connections with a multimeter. i tested -m c123xor, -m c123 and the default firmware. flashing custom baudrates was no problem. rivers are installed correctly (stady ttyusb0 under ubuntu/ com1 under win). is there any hint? -- View this message in context: http://baseband-devel.722152.n3.nabble.com/cp2102-betemcu-B75937-tp3489336p… Sent from the baseband-devel mailing list archive at Nabble.com.

Hello. I have some motorola phones that they are no longer required by my friends. These phones are with the filter rework done. The phones are complete with serial and antenna cables but can be sent without them. If anyone is interested, please send me a msg at irc (OsmoCarpenteR), do not reply to this msg. Thanks.

Poll: Osmocom meeting 25th of July?
by Harald Welte 23 Jul '12

23 Jul '12

Hi all! On Wednesday, 25th of July we would have the next Osmocom meeting berlin. However, neither Holger nor I will be in Berlin on that day to host the event. I also know that Tobias will not be in Berlin. Nonetheless, if there are other people that want to meet up, there is no reason to not hold it! So I would like to get some feedback on who would want to attend next wednesday. If there are a couple of people, I'll try to find somebody who can open the CCCB for you.

Tooling up for osmocom, gnuradio, and android ... suggestions ?
by John Case 21 Jul '12

21 Jul '12

I am a mac and NetBSD user and have not run any linux systems for many years. I have never used Debian/Ubuntu/etc. Now I would like to begin doing work with osmocom, GNU radio, SDRs and some android development. I knw it's a religious question, but since I am starting with a completely blank slate, what would be the simplest, most painless distro to set up a development and build environment (cross compiling for arm, building osmocom, gnu radio, and running android development tools and SDKs) ? I assume the answer must be either Debian or Ubuntu, but really have no idea ... comments ? I think the nicest thing would be a distro that *already* had a full complement of the GNU devel/conf/build tools that all the examples in the wiki rely on ... so I wouldn;t have to worry about getting that environment up from scratch ... Thanks.

Receiving on TS=1 ?
by Sylvain Munaut 20 Jul '12

20 Jul '12

Hi, I've hacked something together to quickly test non-combined CCCH. However, I've hit a problem when trying to receive anything on another timeslot than 0. The TX side seems to work fine as the BTS can see my location update request and answers with a reject, but on the MS side, I never see the reject and wireshark only shows invalid incohrent data on the RX. The frames for SDCCH/8 show really nothing valid (looks like random bytes), things like 09 80 7f 47 49 06 1d 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 09 00 47 d5 2d 06 1e 00 00 69 7c a0 91 3d 22 ff ab fe 6c 4f 56 4f 36 ... while the frames for the associated SAACH show at least something gsm-like : 03 03 01 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b 2b but that's not quite a SI5/6 ... To RX/TX on TS=1, I just delayed the RX/TX window by 625 bits (4 * 156.25) when I'm in dedicated channel mode by chaning the 'start' in l1s_tx_win_ctrl / l1s_rx_win_ctrl Is there something else that should be done ? Cheers, Sylvain

Hi, everyone interesting the topic, this is my latest patch for TCH decode, fix few bug; but it not work well for TCH AMR decode, welcome everyone interesting it to review it and modify it! the most problem now I think is the capture of the Correct TCH frame, at the last ,there is some output for analysis --- app_ccch_scan.c 2012-03-14 16:08:11.305112000 +0800 +++ new_app_ccch_scan.c 2012-07-19

Is OsmocomBB save for use in Live Networks?
by Martin Haug 18 Jul '12

18 Jul '12

Hello, I am using a mobile phone with OsmocomBB on it, but with transmission disabled, because I dont have a private GSM-Network. Do you think it is save to turn tramission on or is Osmocom not reliable enough? greetz Martin Haug _________________________________________________________________ Free-Mail Postfach (bis zu 10 GB E-Mail-Speicher) SMS, MMS, Fax und vieles mehr - http://www.smart-mail.de
