Some hardware to give away
by Sylvain Munaut 27 Apr '25

27 Apr '25

Hi, Anyone interested in some osmocom-bb / phone related hw ? I got some compal phone in pieces (but all pieces should be there to rebuild 4 phones, I had just extracted the motherboards to make a more compact 4-phone setup but never got to it). I also have sci-phone g2 (it's open with jtag soldered) and another phone (mobitel el570) that I don't remember the state of ... All to give away as a complete lot, I'd just ask you to pay shipping from Belgium to wherever you are. Cheers, Sylvain

Looking for BS11 mounting plates
by Alexander Huemer 29 Dec '24

29 Dec '24

Hi! I am in possession of a pair of Siemens BS11 mounting plates and am looking for a second pair. A photo of the plates is attached. Since - I believe - most people who play with such basestations do not mount them to a wall or pole, my hope is that some unused ones are floating around somewhere. Thanks, -Alex^Wblackbit

Osmocom bb mobile station cannot register to YateBTS basestation
by nish079858＠gmail.com 03 Oct '24

03 Oct '24

I am having trouble connecting my osmocom bb setup to a conventional basestation setup using the mobile application, and would really appreciate any help in this matter. My basestation is a YateBTS setup setup on radio band DCS1800 with ARFCN 555, and PLMN 001 01 (test network). I am using sysmocom SIMs with PLMN 999 70. I have verified operation of YateBTS by connecting two other phones and am able to get service on them and even do phone calls. For my osmocom bb setup, I have a motorola c115 device in which I load the e88 layer1.highram.bin firmware. The firmware loads correctly and am able to detect the basestation when I run cell_log application. However when I run the mobile application, I seem to be stuck in RR connection pending. Mobile application does see the cell connection and MM connection seems to be active, and is able to read the SIM card correctly also, just doesn't seem to complete the registration. Here are the logs, and config file I used. Really appreciate any help with this. Thanks in advance!! ---------------------------------------osmocon logs------------------------------------------ Synchronize_TDMA =>FB @ FNR 378464 fn_offset=189241 qbits=4920 LOST 1907!

how to run osmocom-bb with grgsm in usrp b210 to connect openBTS?
by hellowangfang＠gmail.com 19 Aug '24

19 Aug '24

I used osmocom-bb and grgsm with usrp b210 to connect openBTS, but failed. The command is "./mobile -c /home/oi/wf/osmocom-bb/doc/examples/mobile/default.cfg","./trxcon -p 5075 " ,"grgsm_trx -p 5075" . When i used “./cell_log -A 1 ”， it could find plmn 1-1 with arfcn 1 which is same with openBTS. DSUM INFO cell_log.c:344 Sync ARFCN 1 (rxlev -105, 1 syncs left) DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:344 Sync ARFCN 1 (rxlev -105, 1 syncs left) DSUM INFO cell_log.c:190 Cell: ARFCN=1 MCC-MNC=001-01 (Test, Test) But when test with sim testcard 1, it failed to find the 1-1 cell. Could anyone give any suggestion about this? Thanks a lot! 6.5.0-25-generic #25~22.04.1-Ubuntu osmocom-bb: commit 0d1ab4c8d2cbe0ba72662d5b466fb6c60cb8b45f (HEAD -> master, origin/master, origin/HEAD) grgsm: https://github.com/bkerler/gr-gsm.git origin/maint-3.10_with_multiarfcn
