Mon Dec 10 09:15:49 UTC 2018

Hi All,
I am able to bring up srsenb binary and to resolve this issue, I upgraded UHD version relevant to USRP B205mini-i.
Now, S1-setup is happening between srsepc and srsenb but getting the following message on the srsenb console.

Is it just console log or some error ?If this is an error, please help me out to resolve this.
Thanks,Vimal

I am using following RF configuration to run srsenb .

Here device_name is "UHD". Through command "uhd_find_devices", I am able to see device but whenever I run "$sudo srsenb" , it does found UHD device. 
Just to verify, how things are working for device name comparison , I introduced a new line "printf("Device Available %s \n", available_devices[i]->name); " into file the srsLTE/lib/src/phy/rf/rf_imp.c 

After compilation, I again ran the new srsenb binary, I got he following logs:

It seems that device Available list does not have entry for UHD and the reason could be the ENABLE_UHD flag in not used during compilation.

Please help me out to resolve this issue. I am using USRP B205mini-i. 
Regards,Vimal
