[srsran-users] Question regarding srsenb delay channel emulator

[DANG Anh Khoa]

Hello everyone,

I am new to srsRAN platform, and recently I have been using srsRAN for my project.

I have successfully set up 4G with ZMQ srsRAN locally based on the tutorial (https://docs.srsran.com/en/latest/app_notes/source/zeromq/source/index.html#srsran-with-zmq-virtual-radios).
I am able to use the downlink channel emulator (fading, rlf) with default values on enb.conf.
However, the delay parameter is not working and causing Attach Failed (5/5) on srsRAN:

[channel.dl.delay]
enable        = true
period_s      = 3600
init_time_s   = 0
maximum_us    = 100
minimum_us    = 10

The configuration for srsRAN overall is the same as in the tutorial.
I have checked the website and tried to vary some delay parameters, but it is still not working. Is there something that I am missing?

Thanks and best regards,
K.A. Dang
