Re: [Openbts-discuss] Pls check out my approach! Phones still cant connect to network/B200

[Ralph A. S. d. <ra...@sc...>]

When trying to register, did you already check if the phones transmit, and if so, what they do transmit? Can be done with a scanner, tuned to uplink frequency, mode AM (FM will not work!!), squelch open, or when the phone is put on PC speakers or a cheap clock radio that produces the typical GSM machine gun sounds from interference. 

 

When you only here two or three very short (sometimes barely audible) clicks, it is possible that some UHD stuff may not work. In this case the phone sees the network, transmits RACH bursts to set up a dedicated communication channel, and does not get the right answer in time. 

 

When you here some typical GSM-like tack-tackatack-tackatack-tack noise, the physical RF layer works in both directions, the SDDCH is established, and UHD should be fine then...

Subject: [Openbts-discuss] Pls check out my approach! Phones still cant connect to network/B200

 

Dear community,

I still couldnt get my phones to connect to my test network (which is being shown) on my B200, which I have bought 3 weeks ago.
Please check out my approach and find the mistake, if I made one, meanwhile I am really desperate:

Fresh Ubuntu 14.04.4 32 Bit Desktop Install

sudo apt-get install libboost-all-dev libusb-1.0-0-dev python-mako doxygen python-docutils cmake build-essential

git clone git://github.com/EttusResearch/uhd.git
or
git clone --recursive git://github.com/EttusResearch/uhd.git

cd uhd/host
mkdir build
cd build
cmake ../
make
make test
sudo make install
sudo ldconfig
sudo /usr/local/lib/uhd/utils/uhd_images_downloader.py

In root dir again:

$ sudo apt-get install software-properties-common python-software-properties
$ sudo add-apt-repository ppa:git-core/ppa
$ sudo apt-get update
$ sudo apt-get install git

$ git clone https://github.com/RangeNetworks/dev.git
$ cd dev
$ ./clone.sh
$ ./switchto.sh 5.0
$ ./build.sh B200

$ cd dev/BUILDS/2016-03-15--10-53-14/
$ sudo apt-get install software-properties-common python-software-properties
$ sudo add-apt-repository ppa:chris-lea/zeromq
$ sudo apt-get update

$ sudo dpkg -i libcoredumper1_1.2.1-1_i386.deb
$ sudo dpkg -i liba53_0.1_i386.deb
$ sudo dpkg -i range-configs_5.0.0_all.deb
$ sudo dpkg -i range-asterisk*.deb
$ sudo apt-get install -f
$ sudo dpkg -i sipauthserve_5.0_i386.deb
$ sudo apt-get install -f
$ sudo dpkg -i smqueue_5.0_i386.deb
$ sudo apt-get install -f
$ sudo dpkg -i openbts_5.0_i386.deb
$ sudo apt-get install -f


$ sudo start asterisk
$ sudo start sipauthserve
$ sudo start smqueue
$ sudo start openbts

$ sudo stop openbts
$ sudo stop asterisk
$ sudo stop sipauthserve
$ sudo stop smqueue

Fnding the network and connecting to it:

$ sudo start openbts
$ sudo /OpenBTS/OpenBTSCLI
config GSM.Radio.RxGain 10
config Control.LUR.OpenRegistration .*

Restarting OpenBTS

$ sudo stop openbts
$ sudo start sipauthserve
$ sudo start openbts
$ sudo /OpenBTS/OpenBTSCLI

After all these installations and configurations the network "PLMN 1-1" is showing up but my phones still cant connect to it. 
So the IMSIs of the phones can also not be shown in the imsi table.

Did I miss sometihng out?
Is the recent UHD version (3.10.0) to new for my new B200?
How do you guys install UHD:
git clone git://github.com/EttusResearch/uhd.git
or
git clone --recursive git://github.com/EttusResearch/uhd.git
?

Thanks for helping out guys!

Best regards,
Alex
