Please be aware that the ANTSDR E316 is not officially supported. Therefore, we're unable to address issues related to this device. We kindly request that you move your post to the Discussion section, where our community members may be able to assist you further.
Great idea! Feel free to voncert this issue in a discussion (it don't seems like we have the permissions to do so). I would point out that we have managed to run a 4G network (with the srsran 4g project and uhd) on the E310 without any problems (we connect with a Nokia TA-1362). If we try to observe the frequency band that should be occupied, we don't observe any activity on it (in 5G). However, everything in the logs seems to indicate that the gnb has started up correctly.
Please open a new thread in the Discussion section.
Issue Description
Everything seems to be starting up, but I'm seeing a series of strange messages in the logs + I can't detect my network on the UE
Setup Details
I work with an ansdr E316 from microphase with an external GPS. Here is my configuration file (from GnodeB):
Expected Behavior
I should see my network in my UE
Actual Behaviour
When trying to use my gps (by setting clock and sync to gpsdo), I've got the error:
Could not lock reference clock source. srsRAN ERROR: Unable to create radio session.
I've got in my terminal some [DEBUG] [AD936X] baseband bandwidth too large for current sample rate. Setting bandwidth to: 5e+07 but it's impossible to manually set the bandwidth to 50Mhz (srate to weak) which is a strange behavior. I can't increase my srate neither because it seems like it needs to be equal to the clockrate and my clockrate is limited to 30.72 Mhz (I tried to overcome this problem by using the GPS but as stated before it isn't working). My ideal configuration would be to use a frequency of 4005 Mhz with a 20 Mhz bandwidth and I don't really care (for now) about the srate.
Additional Information
Here is the "complete" trace of execution of gnb
