[srslte-users] N300 problem to attach UE

[Daniel Bulanov]

Hello,

I have problem to attach UE for srsLTE

*The initial parameters:*
OS: Linux RSCHR 5.8.0-55-generic #62~20.04.1-Ubuntu SMP
ENB: USRP N300, UHD 3.14.1.1, srsENB(LTE) installed from source.
UE: MEIZU U10 (U680H)
S1 link is up, the ENB connected to the Core.
Bandwidths 15 MHz, the sample rate for this Bandwidth is supported by N300.
PLMN is broadcasting and recognized by UE. UE sees the network. The unique
MNC is set.  The EARFCN is supported by the UE.
Manually set up the RX/TX for USRP.

*Problem:*
UE Won’t Attach
There is no signal from USRP out

*What we have done:*
We have checked the Pickup file, it is empty.
There is no exchange between Core and EbN to attach UE, no attach requests.

The same configuration worked with USRP B210 last year.

Thank you in advance for your kind help!

Best wishes,
Daniel Bulanov
