Hi,
I tried to connect my commercial phone(HTC) to openlte but failed. I ran "telnet 127.0.0.1 30001" on a terminal and it printed lots of error information as following:
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

And then the phone showed your sim card does not allow conncection to this network.
Any reply is warmly appreciated.
With my best regards.
Please examine the generated pcap file /tmp/LTE_fdd_enodeb.pcap in wireshark. If the only content is MIB, SIB1, and SIB2, then your UE is not attempting to attach. If there is more content, it can help diagnose connection failures.
Hope this helps,
Ben
Thank you very much for your replying. The /tmpLTE_fdd_enodeb.pcap is only 24bytes. I opened it in wireshark and nothing was displayed. Could you give me some suggestion to find out the problem? Thank you very much. With my best regards.
Jennifer,
Sorry for the delayed response. My apologies, PCAP support is turned off
by default. Please turn on PCAP support within the eNodeB before running
your test (write enable_pcap 1).
Thanks,
Ben

i tried write enable_pcap 1 but the errors still persisted . i am using openlte_v00-20-04 please help me with this problem.
I am using Ettus USRP N210, enode is up but i am unable to find the network during scan. Also, pcap file shown 0 bytes captured, although i have set the parameter as 1. Anyone to guide
