The transceiver presently only has support for EDGE with LimeSDR and so you will need to add “-e” flag.

Tried it. The same.  
Sometimes it starts, but the phone registration is impossible.

The best place for support is probably going to be the Osmocom mailing list.

Hi,  
osmo-trx works with LimeSDR in EDGE mode only. You need to run it with ‘-e’ flag (‘osmo-trx -e’)

Only question on my side is above bold USB 2.0, my lime is on normal 3.0  
working with other SW like Cubic or Angel like 3.0

Djani,  
I see you have had success in getting osmo-trx working with LimeSDR. I thought I had mine working with the osmo-trx main branch but immediately after it starts with the message…

“Transceiver active with 1 channel(s)”

The red indicator LEDs all turn green and the TRX on the Lime appears to stop operating. There is no error message, it just stops. Does your LimeSDR do the same when you try to activate osmo-trx?

It is the same.  
My understanding is that osmo-trx expecting some instructions from rest of the SW chain.  
Which is not installed in my case.

Here also no luck with telnet of Commands on the Per-ARFCN Control Interface,  
in accordance to READ ME

I was thinking the same thing about the TRX issue. Maybe it puts itself in a stand-by mode and is waiting to be triggered.

However, the MyriadRF/Osmo-TRX fork I’ve been using sucessfully for Osmo-NITB etc. goes straight into actively rx/tx mode. This is how it looks when using this older fork…

I’m running Ubuntu 16.04 Desktop and if you just want to get things working in the meantime the old fork at [https://github.com/myriadrf/osmo-trx](https://github.com/myriadrf/osmo-trx) is working fine for me.

@zodiac-tiger @9a4db do you have OsmoBTS and OpenBSC installed also? OsmoTRX won’t do _anything_ useful on its own. Paired with OsmoBTS it gives you the logical function of a GSM BTS, which is configured with an ID and details of which band to use and BSC to connect to. The BTS must then connect to a BSC instance and so on.

You can run OpenBSC in “network-in-the-box” mode, where it provides a BSC plus just about everything else you need for basic voice call support, or in other modes, including BSC only. For more details see:

[https://osmocom.org/projects/openbsc/wiki/OpenBSC#Configurations-Modes](https://osmocom.org/projects/openbsc/wiki/OpenBSC#Configurations-Modes)

Yes Andrew,  
but any way, one cooking (Lime) book for dummies can be useful 😊 too.

Actually I have been successfully running OsmoNITB and OpenBTS using the MyriadRF/Osmo-TRX fork for a couple of weeks now.

I’m running an Ubuntu 16.04 Desktop as a WM using the newest VMWare Fusion on a Macbook Pro [2.5 Ghz i7 w/ 16 gb of ram]. Running it over USB 3.0 works well minus some small performance issues, but using it on USB 2.0 is nearly impossible. It starts working but very quickly the network breaks with a warning of ‘popping from tx’ and must be restarted to become functional again. I’m lucky to go 5 mins before the network is overwhelmed by small amounts of network traffic or other cpu processes. Its even worse on my Late 2007 Macbook that has Ubuntu 16.04 Desktop running bare metal. Frankly, I was so surprised when I saw your demo of the LimeMini for OsmoNITB running smoothly on a raspberry pi 3.

So, I was thinking that my USB 2.0 problems may be related to using the old MyriadRF/OsmoTRX fork.

Just to make sure I’m understanding this correctly, the MyriadRF/Osmo-TRX fork is now basically obsolete, right? Because the Lime functionality has been integrated into the main Osmo-Trx branch on Git, correct?

With the newest Osmo-TRX from Github installed I get this far…

```
sudo osmo-trx -e -a "driver=lime,device=0"

```

It appears to run with the a final output indicating the transceiver is active even though all the Lime’s indicator LEDs turn green and osmobts-trx doesn’t connect and start the network.

Any ideas?
