[srslte-users] Having troubles to connect srsUE with srsENB

Hi,
No, I did not find any solution yet. I have also tried to connect enb;
running over BladeRf; and real UEs. Unfortunatly, UEs are not even capable
of detecting the created srslte network. I have tried 3 different phones:
Samsung Galaxy 7 and 8 and Huawei (I do not remember the model but it is a
new one).
One additional remark is that when I have srsUE running on BladeRf too, not
only it can not detect enb but the network interface "tun_srsue" is not
created.
After going throughout many srslte related discussions/forums, I have the
impression that usrp was most tested/used as enb than BladeRf. So, I
suspect that my problem is related to hardware.
Please let me posted if you come up with a solution.
Thanks
Mohammed
