[srsran-users] srsENB @ 20Mhz BW

[Philip Shaw]

Hi All,

Please can I have some help on this.

So, I have a new fast PC driving a bladeRF running EPC and ENB.  I have a fast PC driving a ETTUS x300 running UE.  These connect and work only up to 3M BW.  If I set the ENB nrb>15 I do not get any connection (no error is shown).

If I reverse the setup (bladeRF running UE and the ETTUS running EPC and ENB), then it works all the way to 20M BW.

I need the UE to be on the ETTUS, ENB / EPC on the bladeRF.

What could be the issue here?  The blaldeRF has been confirmed to be transmitting (as a ENB) at 20M BW - not sure if the information within the signal is correct but the signal is there on a spectrum analyser.  The version of srslte on the PC driving the ETTUS is from 18 months ago.  If this is a possible issue, what is the procedure to update  - do I simply do a new install from source over the current version or does this need removing first?

Many thanks for your thoughts please.

Philip
