[srsran-users] srsENB @ 20Mhz BW

Hi all,
Following on from my last post - could this error (Buffer Pool is empty) occur at the higher sampling rates if the host PC is too slow?
I would appreciate any thoughts on this
unclear what the USB port speed is. Dell Optiplex 3020 i54590T made about 2014 

Thank you
Philip

Hi Andre,

I have a ETTUS x300 + UBX160 running srsUE and a bladeRF A4 (FPGA=v0.14.0, firmware v 2.4.0) running epc and enb.
I set n_prb=100 and start epc and enb on the pc connected to the bladeRF.  I get the error Buffer Pool is empty.
If I set the n_prb= 6 or 15 it works fine.

Thank you

philip

Hi Philip,

please provide more details on your setup, etc. The 20 MHz link should work nicely with various Ettus HW, e.g. B210, X310, N310 but also Nuand bladeRF.

Cheers
Andre
