Re: [Discuss-gnuradio] How to run OpenBTS? Where to subscribe the openbt

I didn't know that there is a mailing list specified for OpenBTS. What's the e-mail address?

I tried to install OpenBTS. I made it successfully by "make" command. However some files, e.g. the files in "tests" directory, are not compiled. Also, apparently, "make install" does nothing! No library is added to my lib directory.

Anyway, I don't know how to use the OpenBTS library in my script? Shall I use APIs in my C program? Does anybody know about that?

Thanks,

Hassan

Subject: [Discuss-gnuradio] How to run OpenBTS? Where to subscribe the openbts mailing list?

Hi all,

I tried to subscribe the openbts mailing list, but I did not succeed. I sent email to address@hidden to subscribe the openbts mailing list. Could anyone please help me solve the following problem?

I tried to run the OpenBTS according to the instruction. http://www.gnuradio.org/trac/wiki/OpenBTS/BuildingAndRunning.

Start Asterisk.
Start your SIP test phone and be sure that it can register with Asterisk.
Start the transceiver (in Transceiver/). It's best to route the output to /dev/null.
Start OpenBTS<whatever> (in apps/). You probably want to pipe the output through grep.
- "grep Control" to see L3 activities.
- "grep LAPDm" to see L2 transactions.
- "grep SIP" to see SIP transactions.

I am not sure what I did is what the instruction means. Does "start asterisk" mean "asterisk -vvvc"? Does "start SIP phone" means to execute the executable zoiper? How can I know if the SIP phone can register with Asterisk? Does "start the transceiver" mean "nice -10 ./transceiver >/dev/null"? Does "start OpenBTS<whatever>" mean

"./OpenBTS900 |grep Control"?

However, I got Segmentation fault.

#nice -10 ./transceiver >/dev/null
