ipaccess-config perforning tests is broken
by Holger Hans Peter Freyther 09 Apr '11

09 Apr '11

Hi Harald, I bisected this and I end at the commit that moves bsc_init.c code around and moves things to signals. Out of your head would you know if ipaccess-config needs to call some other init function or do something special? If not I will dig a bit more and come back with more details. holger

[PATCH 0/6] openbsc: cleanups for ipaccess tools (2/*)
by pablo＠gnumonks.org 08 Apr '11

08 Apr '11

From: Pablo Neira Ayuso <pablo(a)gnumonks.org> This patchset is the second in the series to cleanup redundant code in ipaccess tools. They have been tested by bootstraping the nanoBTS successfully in a small setup with two laptops, one acting as proxy and another with osmo-nitb. They are available in the pablo/cleanups branch in openbsc git tree. Please, merge it! Thanks. Pablo Neira Ayuso (6): ipaccess-proxy: get rid of make_listen_sock() and use make_sock() instead libabis: ipaccess: conclude new ipaccess_send_*() functions and use them libabis: ipaccess: export ipaccess_idtag_name() ipaccess-proxy: get rid of ipac_idtag_parse() libabis: ipaccess: export ipaccess_parse_unitid ipaccess-proxy: remove hardcoded IP for options `-l' and `-b' openbsc/include/openbsc/ipaccess.h | 3 + openbsc/src/ipaccess/Makefile.am | 7 +- openbsc/src/ipaccess/ipaccess-proxy.c | 188 ++++++--------------------------- openbsc/src/libabis/input/ipaccess.c | 75 +++++++++---- 4 files changed, 94 insertions(+), 179 deletions(-) -- 1.7.2.3

alternative bts
by Hans Witvliet 05 Apr '11

05 Apr '11

Hi all, A thread on the asterisk mailing list re-triggerd my memory. Last november or so i asked if it might be possible to use a gsm/umts-dongle as a bts. afaicr the general consensus was that it was not possible because the proximity of TX and RX hardware. I have been discussing it with my colleges today and wonder where we were making the obvious thinking-mistake... 1) i know, that certainly at higher powers, the receiver becomes deaf in the vincinity of a (high powered) transmitter, due to cirtuit overload, but in our case we only needs a single miliwatt or even less.... 2) scanning for multiple devices/frequencies is not needed. [the idea is to connect to a single hand-held-device, that is only one meter away, and feed voice through an existing IP-connection] 3) if a dongle is not usable for above reasons as a BTS, why is that same dongle (more-or-less) capable as working as a handheld? Same problems should occur as such, not? http://wiki.e1550.mobi/doku.php If they can tap in the device for audio/sms-client, it should also be possible to do it the other way round, as a single-thread bts.... still puzzled, Hans
