[srslte-users] Attaching a UE to srsENB

[Moncef Nabil Boukhatem]

Hello,

After managing to find my network with the different phones (even if I have some time to wait before finding it), I've faced this error :

Unhandled feature in RRC function: liblte_rrc_unpack_rrc_connection_setup_complete_msg

Do you have any idea about it? I join the logs and pcap of the srsenb.

Thank you for your help,

Best regards,

BOUKHATEM Moncef Nabil

Hello,

I used a beamforming trick using a box and I can finally see the network on my phone. I can also see the RACH in the trace of the eNB but there is the RRC Connection Release problem when taking a look to the pcap (you'll find it attached with the logs) (I've also filed the db_user.csv)

I think that one member did find the solution but I'm not sure, I will look for it.

Thank you for your help,

Best regards,

BOUKHATEM Moncef NAbil

I've already tried that too, and still didn't change a thing.
