Hi,

Im trying to run OpenBTS-UMTS by by using Soapy UHD driver… I have sucessfully run it with USRP B210, but i want to use LimeSDR.

I have this errors:

I’m not aware of anyone having used OpenBTS-UMTS with LimeSDR and suspect it might require hardware support adding to it. This was the case with OsmoTRX (fork of OpenBTS GSM transceiver).

I’d suggest posting details to the OpenBTS list.

Hi Pabilini,

I’ll be thankful if you can share how you accomplished the setup of openBTS-UMTS basestation.

I’m working on linux 17.10.
What version you used for a successful implementation.

Thank you.

I’ve made a stab at putting LimeSDR-USB device in OpenBTS-UMTS/TransceiverUHD/UHDDevice.[h | cpp] enough to at least startup. Way out of my league, but looks like the major device differences are in a table of uhd_offsets:

  • Timing adjustment in samples. This value accounts is empiracally measured
  • and accounts for overall group delay digital filters and analog components.

which vary from 0 for USRP1 to 99 for a B2XX, start the guessing for LimeSDR-USB at 0. It starts up and seems to transmit a spectrum around 950 (Uafrcn 3050) too wide for my rtl-sdr to fully comprehend.

Isha - I was not able to create a working UMTS…

cswiger - Looks promising.Thank you for the interest.

Here’s my changes:

http://swigerco.com/UHDDevice.h.diff
http://swigerco.com/UHDDevice.cpp.diff

It actually uses 125% cpu on an i7-3770 CPU @ 3.40GHz and produces about a 5MHz wide pedestal around 950Mhz with defaults. Would be interesting if it actually works with a phone, I dont have an unlocked 3g around.

OpenBTS-UMTS needs libtool-bin and a very specific version of asn1c that is in the root of the source code, otherwise builds OK in Ubuntu16.04.

Spotted a fellow in Twitter got OpenBTS-UMTS working with a LimeSDR-Mini : https://bastienbaranoff.wordpress.com/ I Tried it with the Mini and that just crashed the transceiver, so reverted to the LimeSDRUSB device in the TransceiverUHD/UHDDevice and reset the UMTS.Radio.Band back to 900 and uarfcn to 2937 and was able to see the network Test PLMN 1-1 3G ok and observe the signal with the Mini.

Will have to researach why the Mini does not work for me.

Hello do you know how to solve this error ?
OpenBTS-UMTS: TurboCoder.cpp:452: TurboInterleaver::TurboInterleaver(int): Assertion `K >= 40 && K <= 5114′ failed.
Abandon

Thanks

Not a clue - seems far removed from the radio layer like it could happen with a usrp even.

Love this comment tho :slight_smile:
//The interleaving is so stunningly complicated that a permutation
// vector needs to be initialized when the channel is created,
// then interleaving works off the permutation vector.

10

Thanks for the reply and I forgot thanks for your patches. Now what can I do ??

11

Is it this the problem ?

I am know face to this problem… I configured UMTS.UseTurboCodes to 0. I have read that it can be solved with a dhcp server but I wasn’t able to make it work please help

So Im trying to set up my limesdr-usb with open-bts umts. I followed the Lime-mini instructions and modified the transceiver file as noted earlier. However I cannot get the Lime to connect to the program. I would like to note that UHD and USRP sees it. I was wondering if anyone could please help

The UHD driver is finding your device, but the openbts-umts UHDDevice code doesn’t know what to do with it:

ALERT 140508222109504 21:04:39.4 UHDDevice.cpp:275:parse_dev_type: found: LimeSDR-USB
ALERT 140508222109504 21:04:39.4 UHDDevice.cpp:299:parse_dev_type: Device not supported by OpenBTS-UMTS

The error basically means that it can’t find something called “LimeSDR-USB” in the options inside UHDDevice.cpp
Most probably you haven’t patched the code with cswiger patches or you forget to recompile after patching

You should have a line like this (among other changes in the patch )

LimeSDRUSB_str  = mboard_str.find("LimeSDR-USB");

in UHDDevice.cpp if you patched it correctly.

18

Yes so I have done the patch as outlined by cswinger. Also I have recompiled , which is why I am at a loss to why it is not working

19

I dont consider myself a programmer, but this code part is quite straightforward:
(from UHDDevice.cpp, including Lime mini and USB support, please note that those are not the only changes required in this particular file )

LimeSDRUSB_str  = mboard_str.find("LimeSDR-USB");
LimeSDRMini_str = mboard_str.find("LimeSDR-mini");
LOG(ALERT) << "found: " << mboard_str << std::endl;

if (b200_str != std::string::npos) {
        dev_type = B2XX;
} else if (b210_str != std::string::npos) {
        dev_type = B2XX;
} else if (usrp2_str != std::string::npos) {
        dev_type = USRP2;
} else if (x300_str != std::string::npos) {
        dev_type = X300;
} else if (x310_str != std::string::npos) {
        dev_type = X300;
} else if (LimeSDRUSB_str != std::string::npos) {
        dev_type = LimeSDRUSB;
} else if (LimeSDRMini_str != std::string::npos) {
        dev_type = LimeSDRMini;
} else {
        goto nosupport;
}

tx_window = TX_WINDOW_FIXED;
LOG(INFO) << "Using fixed transmit window for "
          << dev_str << " " << mboard_str;
return true;

nosupport:
    LOG(ALERT) << "Device not supported by OpenBTS-UMTS";
    return false;

My suggestion would be to add some prints so you can check why the string comparison “LimeSDRUSB_str != std::string::npos” is not working for you.
As a last resort, you can also try to force LimeSDR-USB inside the “else” with
dev_type = LimeSDRUSB;
and commenting out the goto statement.
