First, thank you for providing such detailed information! I'm far from an expert on YateBTS, so I don't know how helpful this will be. I noticed you are receiving a lot of "TX underrun" errors, TX timestamp issues, RX timestamp jumps, and excessive TOA errors. The TX underruns and jumpy timestamps c...

First, download the .patch file attached to issue #416 . Review it to make sure there's nothing nefarious in there (it's fine as of this writing). If you have a checked out copy of yatebts SVN trunk with no local changes, you should be able to have SVN apply the patch for you. Assuming your current ...

Because the RX seems to work, let's try running the bladeRF in external loopback. That is, take one of the SMA cables provided with the bladeRF and connect the RX port to the TX port. Using the bladeRF-cli, make sure the FPGA is loaded, and then set your RX and TX gains to something sensible, along ...
I'm not sure if it's related to your problem, but MATLAB is single-threaded, so the function calls are blocking. What are your settings for the number and size of the buffers being used, as well as the number of simultaneous transfers? How much data are you trying to push through? If you're not send...

Basically, there are three ways to get a clock into or out of a bladeRF : SMB port, J62 (input, output) Expansion GPIO, U74 (input, output) Mini GPIO, J71 (input, output) The SMB port is the best option if you care about phase relationships because this clock signal comes directly out of the Si5338Q...

Maybe? I wouldn't expect great performance or accuracy though, and you may have to build/buy additional components. For one, the bladeRF is not calibrated, so for the best accuracy you'd need test equipment to build a calibration table. You might be able to ignore this, but keep in mind that it coul...
