[srslte-users] Fwd: Having troubles to connect the srsUE

Mon May 13 09:27:12 UTC 2019

Nehemiah --

>From the logs, while your connection seems bad, the NAS attach was
successful at least once.
Can you ping the SPGW at all?

>From what you said previously, you were trying to connect to the
Internet as a test, which is not really a good initial test.
Connecting to the Internet with srsUE requires the routing, the NAT,
and DNS to be configured correctly, which is completely unrelated to
srsLTE.

Ping and iperf are much better for initial testing, so make sure those
are working before trying to connect to the Internet using srsUE.

Cheers,
Pedro

If I continued to run the same commands like sudo srsepc, sudo srsenb and sudo srsue, I would still face the same output as the initial post. I clarify with my supervisor he told me to use command if_masq.sh(if I remember correctly) under srsepc folder. The boards are just placed one over the one He told me it should correctly if I check the active connections I would see the tun_srsue(shown), although I would see the other active connections(WIFI). I am not familiarize with Ubuntu but I assumed that if I see something on the active connections tab, which means the computer is using that internet(srslte server as the base station), I am not very clear on this part maybe someone can help to enlighten me. If it is correct, I would like to thank you guys Francisco and Alejandro for your help. I am now waiting for sysmoUSIM_SJS1 to arrive to configure my own UE. For the smart card reader, I will be using the ACR38U-N1.

Can you run the "pdsch_ue/pdsch_enb" example, as suggested by Alejandro, but in both directions? You can find these examples in your srsLTE build folder (I am gonna assume your build folder is called "build"). To run the examples, run the following commands:

Do correct me if I am wrong, before using a mobile device as the ue, I heard it is possible to connect the computer running the sudo srsue to connect to the internet( from the srslte) . Before that, I have entered several configurations inside using IP address 172.16.0.2.  I am able to see the tun_srsue with the ip address with 172.16.0.2 while looking for active network connections while running the three commands. I have looked into several posts in srslte regarding this matter, please do let me know if I should amend. I will appreciate if anyone can add the steps too. I was told to make changes to the epc.conf file, however I am only able to identify srsue/ srsenb. Down below are the outputs while building sudo srsepc, sudo srsenb and sudo srsue. If you do need any necessary files please let me know. Thanks
