(ETSI EN 300 175-7 Ch. A6)
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

OC=SITE-MANAGER(00) INST=(ff,ff,ff) Sending OPSTART <0005>
abis_nm.c:771 OC=SITE-MANAGER(00) INST=(ff,ff,ff) Opstart ACK
And on the transceiver side, between the successful CLK Indication
messages, i get:
<0011> trx.c:509 [!] No handlers found for command 'RFMUTE'. 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.
Hi
I would like to emulate a R&S Test-SIM.
For that, I need a38 XOR Algorithm.
Would this be possible with SoftSIM and Osmocom-BB?
How do I put /calculate the Ki in the SIM.xml file?
Theres just RAND,SRES,Kc field.
Thanks.
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!
