and it tutorial also : OAI and LimeSDR-Mini
I’ve followed step by step the tutorial of Bastien on https://bastienbaranoff.wordpress.com/2018/10/23/openairinterface-4g-lte-with-limesdr_mini/ . But I got always those output :
When i stopped the program lte-softmodem, i have this prompt :
OS : Ubuntu 16.04.4
LimeSDR mini rev 1.1
LimeSuite version : v18.10.0-g3cbdb8bb
SoapySDR version : v0.7.0-g6d21756e
is it possible to send log with txt ! mine run correctly
Thanks for the reply @dast , I have solved the problem after I discovered a little mistake in my MME config file. I think now it runs correctly :
But after some moments I got this debug message after the “L” : " [PHY][I]rx_rf: rfdevice timing drift of 2720 samples (ts_off 26720)"

Hi ,
We have eNB compiling and running on LMSSDR, however we still have issues achieving and maintaining attach complete with UE.
Below were the error appeared in eNB…

what is your error on mme config ?
I have also the same problem with limesdrmini, Bastien says that you could resolve the problem the touching the antenna to the phone! but it still not run for me! have a look on the comment on it ; https://bastienbaranoff.wordpress.com/2018/10/23/openairinterface-4g-lte-with-limesdr_mini/
Hey I am facing similar kind of issue, while starting lte-softmodem with rf-config-file LimeSDR_USB_above_1p8GHz_2ch.ini file.RF loop back test was fine.

Any idea ?
Hi
can anybody help me to connect UE to eNB?
I have problem of [S1AP] Failed to find ue context associated with eNB ue s1ap id: 0
I can see the network on UE but cannot connect to it!
Here are the logs of eNB, MME, HSS, SPGW:
http://s7.picofile.com/file/8388061134/eNB.html
http://s7.picofile.com/file/8388061150/HSS.html
http://s6.picofile.com/file/8388061168/MME.html
http://s7.picofile.com/file/8388061192/SPGW.html
I’m using limeSDR
At first the UE was in flight mode and the Out of flight mode and then serched for network and at the end i tap on the network to register the UE but it said Unable to connect, Try later
Thanks
If you don’t have any luck here, would suggest asking in the OAI community.
Thanks, but its related to LimeSDR and also i asked there but no one knows!
Right, but as far as I’m aware they developed the LimeSDR integration and so would likely be better positioned to debug any issues with this. I know it has worked before, but I have no idea if this is being actively maintained across Lime Suite and OAI releases.
I have heard of people having more luck with srsLTE and if you have a budget, Amarisoft would likely be the best bet. Assuming your use case is not somehow OAI-specific.
Dear,
is it necessary to use Duplexer? can we not use Limesdr usb without duplexer?
Thanks
hi I was also getting the same error, but when i first installed soapysdr and then limesuit using below command it resolved my problem.
- Install the SoapySDR
git clone https://github.com/pothosware/SoapySDR.git
cd SoapySDR
git pull origin master
mkdir build && cd build
cmake ..
make -j4
sudo make install
sudo ldconfig
git clone https://github.com/myriadrf/LimeSuite.git
cd LimeSuite
git checkout stable
mkdir builddir && cd builddir
cmake …/
make -j4
sudo make install
sudo ldconfig
