[srslte-users] SRSUE cannot send/recieve data

[Tošovský Bohumil]

Hello,

The problem was caused by the only "allowed ciphered traffic only"  on the eNodeB. When I disabled cipherng on the eNodeB, everything works well.

Is there already supported any other algorithms than EEA0 and EIA0  on the SRS_UE ?


Thanks 

Bohumil Tosovsky

Hello,

Please find attached logs, little update: the data are  passed to the Bearer, but when I trace on the S1 interface, they are corrupted in the GTP tunnel.
