Dincer, I believe that you will need to add a resampler to the openLTE code in order to run on a USRP. I don't have a USRP myself, but I believe that they only allow sample rates that are integer divisions of 100Msps (except the USRP B200 series). In order to get a valid LTE sample rate (30.72,

Hi Ben, thank you for your answer. My previous question was bit strange. There are to functions of you, once the dl_file_scan and once the only dl_scan function. I did undertood that the dl_file_scan function kinda works with USRP, but I was not sure about the dl_scan function. I read here t

Dincer, Hopefully this will clarify things a bit: 1) The dl_scan application will not work with USRP currently due to the resampling issue. Since gr-osmosdr will support USRP, the dl_scan application should run using a USRP, but the sampling rate will be incorrect and it will not decode anything.

Hi Ben, many thanks for your clarifying answer. I will need to think little bit about 2). But I have another Question: Why did you not use a usual Python flowgraph (like in file scan) but a C++ flowgraph? Is there anywhere a python flowgraph for the live scan app? Thanks again, Dincer Von: B
