[srslte-users] Multiple UEs using zeroMQ

[GINES GARCIA AVILES]

Hi,
thanks again for your help!!
Actually, I was asking for more examples because I was using the ones you
pointed out without succeeding. The UE gets stacked during cell search
without any log messages.

Anyways, I will continue testing a bit in order to see where the problem
could be.

Thanks,
Ginés.
