Expected Behavior

I want srsue to connect to srsenb.

Actual Behaviour

Nothing happened.

srsenb

New test(I haven't tried using pdsch_enodeb and pdsch_ue yet. I will go back to the test after class at 11pm tonight.) Hi，

This time I retested and there was a new problem. The following is the ue side running log added later. ue_positive_value.log ue_negative_value.log

Thank you!

andrepuschmann commented 5 years ago

Hey, please send the UE logs along. In general we suggest you should make sure that this setup works with pdsch_enodeb and pdsch_ue first.

MIKEXU2017 commented 5 years ago

Hi,

Can anyone help me with this?This has confused me for a long time, or someone told me what is wrong with the tests of pdsch_enodeb and pdsch_ue?

Best regards, Mike

Zethernos commented 5 years ago

Hi Mike, I am new to this project, currently I am facing the similar situation as you. I apologize that I am unable to help you. However, I am tasked to complete this project, I hope we can help each other to build srsLTE successfully. I am totally new to Linux just started about 3-4 weeks ago, won't say I am confident with it. Trust me I posted on the srs forums and blade for help, the posts I have sent doesn't seem to have been posted on the forums.

Currently the set up is on Ubuntu 16.04 and 18.04. On the 16.04, it has the b210 and on the 18.04, it has the bladeRF x115.

However, I am facing some difficulties, may I know what are the steps to use UHD 3.9.7 because I tried to download. Before that I have uninstalled uhd, before installing UHD 3.9 LTS. It is not working for me but I am unable to figure it out. Besides that, after running the commands below, i tried to rerun the commands, it displayed error like: UHD error code 11. Hope someone is able to guide me
