[srslte-users] bladeRF setup with srsUE

[sanya454545]

Hello!

I’m having some trouble getting srsUE to run with my bladeRF. I had to install the soapySDR wrapper in order for srsUE to find the bladeRF, and now this happens when I try to start srsUE:

"""

.... and then it hangs forever and nothing happens. I did try setting the value for the burst preamble manually in the config file (I set it to 0, as the comment said to), but the output is exactly the same.

I'm a bit new to all this, and have spent some time reading the bladeRF wiki to see if there's anything I can configure to fix this, but I'm not totally sure.

Everything works perfectly with my USRP btw! Any help would be appreciated. Thank you!
