Thanks,

Will look for one here,  
by the way which TX & RX channel does osmo-trx use by default, maybe I just didn’t connect the antenna to the appropriate channels

and is there anyway to change or edit these settings ??

Thanks again for the help

what is the difference ?

and I’m not exactly sure how to choose versions other that the git checkout command

I found on my computer soapy version 0.6 can detect my limesdr board while 0.7 can’t

also the newest version of soapyuhd has problem.

you can go on github find the repository you want and click releases, you will find all old versions.

Here’s an example:

The later versions of osmo-trx specify antenna in the osmo-trx.cfg file:

```
trx
 chan 0
   rx-path LNAW
   tx-path BAND1
```

Please see [http://osmocom.org/issues/2919](http://osmocom.org/issues/2919) for updates on this. Progress is unfortunately slow due to a variety of issues, including us at sysmocom having apparently too old and now unsupported v1.0 hardware. We’ve also hit [https://github.com/myriadrf/LimeSuite/issues/193](https://github.com/myriadrf/LimeSuite/issues/193) and [https://github.com/myriadrf/LimeSuite/issues/184](https://github.com/myriadrf/LimeSuite/issues/184) during development, and we still are unable to explain why the Tx GSM signal looks great on a LimeSDR-mini 1.1 but way out of spec on LimeSDR (classic/USB). Feel free to join the thread at [http://osmocom.org/issues/2919](http://osmocom.org/issues/2919) and/or help with development and testing. Thanks for your patience!

Thanks for the reply, but I couldn’t find this configuration file.

I finally got my hand on an RTL-SDR

just to clarify, I’m using limeSDR board 1.45, with TX1\_1 and TX1\_2 connected to antennas and RX1\_H and RX\_L also connected to antennas.

as you can see in the attached picture, I have everything setup as it should be, but I still can’t see the network, and I don’t think the board is transmitting even though it’s getting HOT !

attached are the pictures of the setup and reading from RTL-SDR

 ![RTL](https://yyz2.discourse-cdn.com/flex034/uploads/myriadrf/original/2X/5/55fe81ff9ee8b5c08491c84342018ac3dfd1a0f5.PNG) ![LimeSDR](https://yyz2.discourse-cdn.com/flex034/uploads/myriadrf/original/2X/f/f45e159b351f85e966fd1d2f7b97f021f027efc5.PNG)

Any ideas ?

That actually looks like a low gain version of what I first got: [OpenBTS 1st test](https://discourse.myriadrf.org/t/openbts-1st-test/823)  
The solution _then_ was to use the switches: osmo-trx -f -e  
Then preferred was: osmo-trx -f -s4 -b4

For the new version, -f is, ah I think, this C0 Filler Table in the vty (telnet 0 4237)

```

I have encountered the same problem. I still don’t know how to solve it after reading other people’s responses. Did you finally solve the problem?

After about a day’s worth of work, I can launch osmo-trx-uhd with the new LimeSDR mini that was shipped in July 2018.

But, I can’t get any radio samples/data flowing using osmo-trx. See the below. The config I am using for this LimeSDR mini is the same as LimeSDR (with the IP addresses for my setup). My core is on a separate IP. That same core works fine with an Ettus UHD/radio setup also with osmo-trx.

Any ideas?

Sadly, no.

I stopped trying after a while. will continue soon.

what is the issue that you are having exactly ?

OK. Making progress after lots of effort.

Now, the issue with LimeSDR mini seems to be related to the clock. I have a high quality 52 Mhz reference that I would like to use. How do I enable this?

Note that within about a minute, the “VCO” frequency goes from 5 Mhz to 2 Mhz then to 7 Mhz. Although I have a BTS “successfully” sending/receiving data, there is no beacon visible to phones and also an RF sweep (at least in the range I am expecting) doesn’t pick anything up either.

Thanks, John

In short:

- Avoid using OsmoTRX via SoapySDR and UHD from now
- Build Lime Suite from git master
- Build OsmoTRX from git master and configure with LMS support
- Use osmo-trx-lms

Direct LMS API integration has been done and should be far more robust/reliable.

Looks like Osmocom wiki is yet to be updated and there will be a how-to guide in due course.

does that mean that I can use the osmo stack for a full GSM network ?

I mean is it easier than going to openBTS with osmo-trx ?

Yes, GSM voice plus GPRS.

For me it is, yes, because I’m not familiar with OpenBTS, but I am familiar with Osmocom. “easier” is pretty subjective 🙂

hmmmm ,  
I’m going to start trying with OpenBTS. however, is there a simple guide for osmo ?  
if you guys are working on one and want someone to test, I am willing to give it a try.

Is libosmocore, not libsomocore

Thanks for the correction.

I was following this link  
[https://osmocom.org/projects/osmotrx/wiki/LimeSDR\_Build\_From\_Source](https://osmocom.org/projects/osmotrx/wiki/LimeSDR_Build_From_Source)

but now I realise that this uses omso-trx with UHD and soapySDR. which what andrew did not recommend.

so how do I compile the osmo-trx with LMS support ( the command doesn’t even work with the current compiled version of osmo-trx)

any help is highly appriiciated

Use that guide, but in the configure step specify to build with LMS driver support, i.e.:

```
./configure --with-lms

```

You can still install SoapySDR and UHD if you like, but they are not needed and don’t try using osmo-trx-uhd binary if this gets built. Use osmo-trx-lms instead.
