Hello,
I am trying to get YateBTS working on a BladeRF with Ubuntu. Everything is built and my unlocked phone can see the BTS in its network list. However, when I select this network, it hangs for a while and fails. I get this in the logs when this happens:

I am not sure what these other errors are, but any idea what "2015-07-28_21:55:26.271317 <mbts:NOTE> RadioResource.cpp:243:AccessGrantResponder: RACH burst for unsupported service RA=186" means?

The latest version of YateBTS has some issues with the transceiver that affects the functionality.
Please use a YateBTS prior to SVN revision 504.
First make uninstall to the current YateBTS, and then install the older version. Keep in mind that the older version has a dependency on libbladerf-dev, so you need to have it installed.
Please make sure you don't have the new transceiver (gsmtrx) and the old transceiver running at the same time (transceiver-bladerf). They use the same port and this will affect functionality as well. The need to uninstall the new YateBTS is just avoid this issue.
