Configuring LimeSDR-mini with srsLTE #437

Closed mikehibbett closed 4 years ago

mikehibbett commented 4 years ago

I have had many difficulties getting LimeSDR mini to work with srsLTE. None of the online guides worked for me.

I now have a tested setup that works, for me, which I would like to share with others. Apologies for sharing on the 'issues' list, but this is where most people will look for solutions. Admins, feel free to close - unless others repeat this sequence and have issues, I will be happy to assist resolving.

Setup

My system is an Intel i7-3770T CPU, 8GB RAM, 128GB SSD. I am running Ubuntu 18.04.3 in a dual boot configuration. The setup described below follows from a fresh installation of the OS, as I wanted a reproducible setup from a clean install. Having worked on this for days, I have got the time for the sequence of "erase old OS, install new OS, build system, get srsLTE running" down to a 25 minute 48 seconds process. I'm sure this time could be improved :)

This setup was created by following and then adjusting the steps from the following two links:

https://docs.srslte.com/en/latest/general/source/1_installation.html https://en.dlyang.me/limesdr-mini-on-ubuntu/

Setup steps.

Start with the LimeSDR mini not plugged into the PC.

Install Ubuntu 18.04.3 64 bit desktop OS. Wait for the OS to advise of updates; install these and reboot.

Open a terminal shell. Enter the following commands, one at a time:

sudo add-apt-repository -y ppa:pothosware/framework sudo add-apt-repository -y ppa:pothosware/support sudo add-apt-repository -y ppa:myriadrf/drivers sudo apt-get update sudo apt-get install pothos-all -y sudo apt-get install python-pothos -y sudo apt-get install python3-pothos -y sudo apt-get install pothos-python-dev -y sudo apt-get install soapysdr-tools -y sudo apt-get install python-soapysdr python-numpy -y sudo apt-get install python3-soapysdr python3-numpy -y sudo apt-get install soapysdr-module-remote soapysdr-server -y sudo apt remove limesdr0.6-module-audio -y sudo apt install soapysdr-module-all -y sudo add-apt-repository -y ppa:myriadrf/drivers sudo apt-get update sudo apt-get install limesuite liblimesuite-dev limesuite-udev limesuite-images -y sudo apt-get install soapysdr soapysdr-module-lms7 -y

Now plug your LimeSDR mini into a USB3 port, and run the command:

SoapySDRUtil --probe

In the output displayed, confirm the SDR is detected, and that it is on a USB3 port. If not, try another USB port.

Now enter the following commands, one at a time:

sudo apt-get install libsoapysdr-dev cmake libfftw3-dev libmbedtls-dev libboost-program-options-dev libconfig++-dev libsctp-dev git build-essential -y

git clone https://github.com/srsLTE/srsLTE.git cd srsLTE mkdir build cd build cmake ../ make sudo make install sudo ldconfig sudo srslte_install_configs.sh user

That completes the installation. Before running the code, I edited the enb config file to get the transmission on a frequency (band20) that is used by my phone in Europe.

In the file ~/.config/srslte/enb.conf change the [rf] section to say [rf] dl_earfcn = 6200 tx_gain = 56 rx_gain = 38 device_name = soapy device_args = rxant=LNAH,txant=BAND2

Now open up two terminal windows. In one, run the command sudo srsepc

In the other, run sudo srsenb

In the output of the above you should see the SDR is detected. The final output should be calibration completed and, in my case, a single "[WARNING] L" message. From this point, I have confirmed on a spectrum analyser that the enb is transmitting.

I have yet to confirm cell information detection by an actual mobile phone, but those are next steps, followed by full connectivity with a test SIM.

SDR configuration

The configuration of the LimeSDR mini used in the tests above can been seen below.

SoapySDRUtil --probe

Thanks Mike for the detailed report. Such a manual would actually nicely fit into the official user documentation which is hosted here. Feel free to submit a PR if you wish. Regarding the config I have one comment. We don't have a LimeSDR Mini to test with but I thought it only uses the wideband antenna connectors, so using LNAW as Rx antenna would be correct. Other may correct me please.

mikehibbett commented 4 years ago

Thanks Andre, I'd be happy to once I get confirmation that others have had the same result. I will test your suggestion out to see if it helps. The LimeSDR Mini has just two SMA connectors, one TX one RX. I presume that setting you mention configures what matching circuit the RX SMA connector is routed through. I haven't got as far as testing a mobile phone yet, but will test your comment.

JamesHagerman commented 4 years ago

For others landing here, I wanted to share a little more information about the details here because it took me a bit to figure out how all this works.

Tl;dr: Based on my limited testing, srsLTE correctly selects antenna ports on the LimeSDR Mini based on the value of dl_earfcn and it shouldn't need to have them configured explicitly.

The LMS7002M has 2 RF channels, each channel has 3x RX ports and 2x TX ports.

The LimeSDR Mini only uses one of these channels. It has two RF switches that allow software selection of which port is connected to the SMA connectors.

On the RX side, only RX1_H and RX1_W are exposed to the SMA RX port through the RF switch (and two different matching networks). The RX1_L port is not connected at all.

On the TX side, both TX1_1 and TX1_2 are exposed, (again, through two different matching networks).

With the default configuration of dl_earfcn = 3400, srsLTE correctly selects LNAH for RX and BAND1 for TX. Those are SoapySDR names for RX1_H and TX1_1 which can be verified by looking at the output of SoapySDRUtil --probe.

This is equivalent to an srsLTE config of device_args = rxant=LNAH,txant=BAND1 which correctly aligns the RX/TX ports matching networks with the corresponding Uplink and Downlink frequencies used on Band 7.

@mikehibbett's config is setting dl_earfcn = 6200 and is also actively selecting ports with rxant=LNAH,txant=BAND2. But the matching networks of those two RF paths do not align completely with Band 20 (6200) which has a Downlink of 796.00 and an Uplink of 837.00. TX is correct, but RX should (as @andrepuschmann said) be on LNAW.

Thank you so much for posting this @mikehibbett and thank you so much for the clarity @andrepuschmann! It helped me learn a lot about both the LimeSDR Mini and srsLTE!

andrepuschmann commented 4 years ago

Thanks a ton @JamesHagerman for the feedback. With all the knowledge gathered in this issue I think it would be great if we could somehow join forces and extend the srsLTE docs page.

mikehibbett commented 4 years ago

Thanks for that clarification @JamesHagerman , that clears it up for me. I'll be doing more work on this in the next month, and will be delighted to build up some additional documentation to contribute @andrepuschmann

Hi @mikehibbett @andrepuschmann

I have done the above, however I get :

Device Soapy not found. Switching to auto mode and then a UHD: code 11, no compatible RF frontend found.

I can find the LimeSDR Mini using both LimeUtil --find and SoapySDRUtil --probe

I'm not sure what to try again. I have installed libsoapysdr-dev

Hello, It appears I might have butchered the installation of srsLTE somewhere or messed up my installation environment at some point. When I run srsenb directly from the build directory after make, without make installing, it runs just fine. Although there appears to be some error on the Tx calibration side

Great tutorial!! I have followed the steps with LimeSDR USB. Now i can run srsue in a machine, run srsenb and srsepc on another machine. Each machine works with a LimeSDR USB. I can see "attach the network successfully" on the terminal of the ue side. But it releases from the network soon. May you all give some comments about this issue? Thanks for your steps. it really helps a lot.

manili commented 4 years ago

Thanks a lot for the tutorial. However I still have problem to identify the network on my iPhone 7 Plus/iPhone 6s with the LimeSDR-USB. The srsENB could identify Soapy without any problem and it works successfully, but I can not see the network in manual searching mode. Any help?

Kind regards, Manili

I am facing the same issue. Although everything seems fine in the log, nothing appears on radio as the image suggests.

Hi,

I'm getting this error: Device soapy not found. Switching to auto mode. That is why srsenb tries to use the UHD driver. Will appreciate your help.

Can you verify that Soapy picks up the Lime ok. There is a bit of LimeSDR documentation in the RPi4 appnote. See here

Thanks Andre. I will work on the steps in the RPi-related page tomorrow. For the meanwhile, what follows are additional information. I did the LimeUtil --update for the FW upgrade. Thanks

Thanks, Joel

andrepuschmann commented 4 years ago

Joel, the issue you are seeing comes from the LimeSDR's Soapy driver failing to set the sample rate. Perhaps you can try with a single channel. Also make sure you have the latest and matching versions of host code and FPGA running. If all that doesn't help I guess you should ask on the Lime list.

Hi,

I already posted on https://discourse.myriadrf.org/t/srslte/1432/17

Hi All, I got this error messages

This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:

joeldelosangeles commented 4 years ago

Hi rembulan

I also encountered the same error. The only dependency which I was able to correct is sudo apt-get install liblimesuite18.10-1. After that the error is the same when doing sudo apt install soapysdr-module-all -y.

Anyway I proceeded to the next steps and soapy-sdr seems to be working after that.

sudo add-apt-repository -y ppa:myriadrf/drivers sudo apt-get update sudo apt-get install limesuite liblimesuite-dev limesuite-udev limesuite-images -y sudo apt-get install soapysdr soapysdr-module-lms7 -y

Hi,

At least, did someone achieve to run fully srsLTE with LimeSDR mini ? On my side I can get my UE attached but I can't go further because of TX issue.

Dastgsm commented 4 years ago

someone says on forum that srslte19.12 is only which run with limesdrmini

phantomdennis commented 4 years ago

@joeldelosangeles, How did you set the reference clock to 30.72 MHz from 40 MHz?

alexballas commented 4 years ago

@joeldelosangeles, How did you set the reference clock to 30.72 MHz from 40 MHz?

@joeldelosangeles uses a LimeSDR-USB, not a LimeSDR mini from what I see. It would be good to focus just on the mini for this thread. The LimeSDR-USB uses 30.72 MHz by default.

andrepuschmann commented 4 years ago

Several changes for the LimeSDR have been merged into srsLTE and LimeSuite/SoapyLMS over the recent past. Please try again with the newest versions and reopen or create new issues if needed. Thanks

jin-github1002 commented 4 years ago

Hi @andrepuschmann which version of srsLTE includes the changes for the LimeSDR? I am using 19.12. I hope to confirm if I need to upgrade to version 20.xx. Thank you so much!

alexballas commented 4 years ago

I tried with the latest (master) versions of both LimeSuite and srsLTE.

Unfortunately it just hangs there. I don't see any outstanding errors when running srsenb.

hi @alexballas what do you mean "it just hangs“？ I saw that you used dl_earfcn = 1875, prb =50, for LimeSDR mini. I tried many dl_earfcn for LimeSDRUSB. I am confused how to find the frequency working stable on LimeSDR USB. My problems is : Only the dl_earfch=1934 ,gain=60 (showed in the tutorial of srsLTE) are stable used on LimeSDR USB when srsLTE runs on desk PC. But when I run srsLTE on Jetson TX2 ( arm processor), above frequency and gain do not work stable. I got stuck here.

Actually I need to run some more tests. I'll update this thread asap with the results.

in limesdrmini i am giving sample rate 5Mhz. based on the sample rate i have to change the buffer size. i don't have an idea. can anyone give some suggestion?

Hola!!

I got my first SDR the LimeSDR-Mini v1.3 and I didn't have any issue at all, even when moving to Band 20. If you use cheap antenna for Rx 800 MHz you may consider 1m thin coax cable plus 50 ohms load for good reception.

What I don't understand is why PLMN configurations are not working. I tried a different MNC MCC but it seems that only 001-01 is accepted by SRSLTE. Actually I can see on my phone Software Radio Systems LTE (TESTING) TESTING is my SPN service provider name in USIM card. I need help, actually the COTS UE Application Note describes how to do that but...

hello can we set up a 5G or 4G network using a single limesdr please
