I’m a new limesdr player,while yesterday i trying to use OpenBTS with my LimeSDR , i met some problems can’t be overcome,anyone could help me?Thanks a million!
Details as Follows:

I’m not aware of LimeSDR support having been added to OpenBTS.

However, support has been added to OsmoTRX:

http://osmocom.org/projects/osmotrx/wiki/LimeSDR

Since OsmoTRX is based on the OpenBTS transceiver and maintains backwards compatibility, you should be able to use it in place of their transceiver.

In theory he should be able to use it with the USRP driver, wich is what he’s doing. I would suggest using the official USRP-Photos driver instead of OpenUSRP.

Yes, but the transceiver software component must have support added for the hardware, as different platforms all have different latencies etc. and GSM is highly timing sensitive. See the June/July commits to OsmoTRX to see how LimeSDR support was added to this:

http://git.osmocom.org/osmo-trx/log/

The same changes would need to be made to the OpenBTS transceiver, else OsmoTRX used in place of this and with the remainder of that stack.

Yes, thanks. I will check this when I receive my board.
