I have setup OpenLTE successfully and now testing with UE, but having some issues scanning the network on my phone. I cannot see the network. Following are the specification for my setup
Host machine: Intel Core i7 with Ubuntu 16.04; the setup is configured on host system
Radio used: USRP N210 series with Ethernet connectivty
phone: Huawei mate 10 lite, SamSung Galaxy s3, Samsung Galaxy Note5; I have configured apn as 'openlte' 'www.openLTE.com'
current CPU frequency is 3.60 GHz.
We are not able to see the network on phone. After lots of debugging, the only improvement I observed is that error is changed into warning. Is there anyone who has suceeded in scanning the network on phone? Kindly guide me where am I worng. I have tried multiple ways out.
Also I want to know what IP address should be given in ip_addr_start. Is it my machine address or device address? I have tried on both but still no luck.
Thanks

Waiting for reply.
Hi Billy,
N210 is not supported by OpenLTE,resampler is required.
Thanks
