Phone without a physical sim to connect to network
by Mario Lucas 30 Aug '21

30 Aug '21

Dear All, I have a running BTS (based on SDR) and i can connect my phone to my network… do / learn some operations… I have a couple of sim cards and each time i want to connect to network with different sim i have to switch of mobile remove previous sim put new one etc etc …. Is there an application that will be running on PC and connected to my phone which will a kind of simulate sim and connect my phone to my network ? Avoiding me each time physically remove previous sim put new one etc etc … Would you be so kind and advise me please… Also another question — is there a «search» option in the archives : http://lists.osmocom.org/pipermail/openbsc/ http://lists.osmocom.org/pipermail/baseband-devel/ just not to post questions which already could have been answered…. -- Mario Lucas

CalypsoBTS with recent OsmoBTS in 2021?
by . 07 Aug '21

07 Aug '21

Hello, I'm trying to run CalypsoBTS as described here: https://osmocom.org/projects/baseband/wiki/CalypsoBTS I'm using a single Motorola C123 phone and in my openbsc.conf, i have only one CCCH+SDCCH4 channel on timeslot 0: timeslot 0 phys_chan_config CCCH+SDCCH4 hopping enabled 0 I'm using the fixeria/trx branch with recent OsmoBTS. First, i load the trx firmware on the phone, and then i start the transceiver host app to sync with a known ARFCN. The syncing goes without any issues. Then, i start OpenBSC through OsmoNITB like that: osmo-nitb -c ~/.osmocom/openbsc.cfg -l ~/.osmocom/hlr.sqlite3 -P -C --debug=DRLL:DCC:DMM:DRR:DRSL:DNM --yes-i-really-want-to-run-prehistoric-software And OsmoBTS: osmo-bts-trx -c ~/.osmocom/osmo-bts.cfg OsmoBTS fails almost instantly with: <0012> input/ipaccess.c:898 received ID_GET for unit ID 1801/0/0 <000b> trx_if.c:701 phy0.0: Response message 'RSP ERR 1 ' does not match command message 'CMD RFMUTE 1' <000b> trx_if.c:645 phy0.0: transceiver rejected TRX command with response: 'ERR 1' <0001> oml.c:221 (bts=0,trx=0): O&M Get Attributes [0], Manufacturer Dependent State is unsupported by TRX. <000b> trx_if.c:134 phy0.0: Ignoring CLOCK IND 2061832, TRX not yet powered on The last message repeats until i terminate the application. On the OsmoNITB side, i get: <0005> abis_nm.c:550 OC=BTS(01) INST=(00,ff,ff) Get Attributes Response for BTS0 <0005> abis_nm.c:463 BTS0 Get Attributes Response Info: 72 bytes total with 0 unreported attributes <0005> abis_nm.c:497 BTS0 Get Attributes Response: reported unexpectedly long (3 bytes) feature vector - most likely it was compiled against newer BSC headers.

Empty response <0011> trx.c:226 TRX Control send: |RSP ERR 1 | Is this issue due to the unimplemented in the transceiver command "RFMUTE" or what really fails is: <0005> abis_nm.c:577 BTS0: failed to parse SW-Config part of Get Attribute Response Info: Invalid argument ? I also tried using components from their circa-2017-2018 revisions but there are so many changes in core Osmocom libraries that they always fail to compile and fixing them is hardly worth it, given the amount of work it is. I know OsmoNITB is abandoned since 2017, but currently this is the only way for a beginner to experiment with BTS based on cheap Calypso phones, as it is not implemented in the new Oscomcom stack.

Help on building the OpenBTS / OsmoBTS Transceiver branch
by . 22 Jul '21

22 Jul '21

Hello, I'm trying to build the transceiver branch for Calypso phones. I installed all OsmocomBB dependencies (including libosmocore) and i sucessfully built and installed libosmo-dsp from the Git repo. My ARM toolchain is from here: https://developer.arm.com/tools-and-software/open-source-software/developer… . When building, however, the compiler fails with: arm-none-eabi-ld: comm/libcomm.a(msgb.o):~/trx/src/target/firmware/comm/msgb.c:35: multiple definition of `tall_msgb_ctx'; ../../shared/libosmocore/build-target/src/.libs/libosmocore.a(msgb.o):(.bss+0x0): first defined here Makefile.inc:135: recipe for target 'board/compal_e88/hello_world.highram.elf' failed I tried both sylvain/testing and jolly/testing branches. What seems to be the problem? Thanks!
