Problems during initial bring-up of nanoBTS
by Harald Welte 19 Jun '11

19 Jun '11

Hi zecke and others, I may have found a cause of one of the problems that we've been experiencing in nanoBTS bring-up, at least at some point in the past. The problem could be observed/described as: During the first OML connect of the nanoBTS, OpenBSC fails to bring it up completely. Second and successive connects worked fine. What I have just noticed is that we never re-set the NM state information for the 12.21 MOs inside OpenBSC. This means, if the A-bis link is lost, the old state information continues to exist. I guess it would be cleaner to simply re-set all the nm_state strucures that are part of the 'struct gsm_bts', gsm_bts_trx, etc. when the A-bis link is lost. As I'm working in this area right now anyway, I intend to produce a patch addressing the issue. But now that I think more about it: I guess it is unrelated to the old problem, as a typical work-around was to re-start OpenBSC, at which time all state is re-set again.

Serial console on FemtoCell
by Bthomas 15 Jun '11

15 Jun '11

Dear Developers, I mentioned earlier that I found a tutorial in which we read that this cell is within the box's serial port. I found him looking for a RS485 port outlet, and 2x5-pin lines of pins. Images from the PCB: http://www.facebook.com/media/set/?set=a.1979958333026.114473.1065188491 IPSEC have read so far by launching tube through a communication gateway through which to get "home location register" information, etc.. Whether there is a chance to even download the firmware via the serial terminal analysis? Or perhaps to be found in lines of pins USB option? The presentation referred to the serial port connection just yet to start when you press the reset button four times, then the boot menu to configure the IP address, login data. greetings: bthomyka

Dear Developers! Currently, the only tool I have found this information: http://users.atw.hu/helvei/UAP3801E.rar?atw_referer=http% 3A% 2F% 2Fmobil- telefon.vatera.hu 2Fmobiltelefon_tartozek%%% 2Fegyeb 2F4_db_huawei_ap_femtocella_mobil_bazisallomas_1459406466.html This is a power point presentation, the pages visible to a certain set of procedures. Although I do not know how much help in the development, but I share with you. Consulted during a programmer who is interested in finding a "reverse engineering" and curious about the possibility of the device, the communication. I am confident that if he succeeds, much of the project promotes the development of OpenBSC. Regards, bthomyka

What might be wrong? Hi, please make yourself gdb and git and create a patch. The struct msgb has detected a mis-use and forced a crash. What is going wrong is in the log, you will need to identify where this msgb got allocated (or change the panic message to print the name of the msgb) and see why it is using the amount of headroom it wants to use. happy hacking holger

Dear OpenBSC users and developers! I beseech you, help me with some information. Today I bought a 4 pack auction Huawei femtocell UAP 3801. Next to them there's no documentation, Huawei has not yet responded to my questions. I want them to operate with OpenBSC. Do you think this tool will work with it? If anyone are having operating instructions, configuration instructions, please share it with me. Thanks, bthomyka
