Hi,
I have run cmake and put the output here:
<https://dk5ras.dyndns.org/tmp/results.txt> https://dk5ras.dyndns.org/tmp/results.txt
Test lower frequencies, my results on the GHz bands were not so promising...however I can try those out these days.
Ralph.

Hi Ralph,
Thank you for the additional information!
I'm definitely on Buster. Knowing that test is failing for you and that you sometimes see calibration errors as well makes me think our setups are pretty close to each other.
I can't understand what's different between our two setups. My test phone is a Oneplus One so it doesn't support band 28... but it does support 5MHz on B7 using 3400 for the dl_earfcn. I wonder if I'm seeing issues due to the higher dl/ul frequencies that you're not seeing down around 763 MHz.
If you could share your simple build and compile script, I'd love to see if there are any differences. If not the script, even the output of cmake might give a clue as to what's different.
I've uploaded mine here: https://gist.github.com/JamesHagerman/7c45b5ae7272daa49d6ee8bc7df05a8d
Thank you _so much_ for all the help! I owe you a beer or something
James

Hi James,
I am running Raspbian buster, nothing special. And I never looked at the tests, I just left the box alone, compiling. However the test fails. I do not have the SDR plugged into the RasPi, and I connect it remotely, as I am 45 km away from it right now. On the other box, Intel i5, Kubuntu, with the SDR plugged in, the test passes.
The hardware setup also is nothing special, the RasPi in a small black metal housing, and the Lime mini plugged into one of the USB3 ports.
One thing is interesting, after the stuff is newly compiled, the first start always takes ages (at least some minutes) with 25% CPU load until the TX starts. And I also sometimes get these calibration errors. Sometimes they go away after replugging the SDR, and usually they appear to be no issue, the cell still works.

Ralph,
Thank you so much for testing this. I'm pulling out my Pi4 and LimeSDR mini now.
I have a few more questions for you:
1. Did all of the tests pass? They take forever to run, but I had one fail last time I ran them against master. Can you please try running "ctest -R pucch_test" and report the results? I opened an issue here: https://github.com/srsLTE/srsLTE/issues/461
2. What version of Raspbian are you running? If your not sure "uname -a" should get me in the ballpark
3. Is your enb throwing any errors? I was seeing [ERROR] Tx Calibration: MCU error 4 (SXT tune failed) and I couldn't get it to go away even after providing more power or trying to calibrate the SDR.
4. Any chance you could share a photo of your pi setup? I understand if you're not interested or unable.
Again, thank you so much!
James

Hi,
nothing special:
dl_earfcn = 9260 #763 MHz B28
tx_gain = 80

And as already mentioned, 5 MHz bandwidth…

Hi Ralph,
In order for us to reproduce this experiment, it will be great if you can share these numbers you are using i.e. frequency, bandwidth, an adjusted RX/TX values.
Many thanks,

Hi,
My config files are all default, I just entered another frequency, bandwidth, adjusted RX/TX levels and changed MCC/MNC to those of my SIM cards. Just needed to make the change in the makefile txt regarding this –werror issue.
By the way, going back to master changed nothing, works all fine.

Hi Ralph,
This is great. I am using LimeSDR in my lab. So, I have few questions.
1- Could you please share your configuration files (epc.conf and enb.conf) with us?
2- Where are located your configurations files? in the .config/ directory?
3-Where is located your user_db.csv? within the same directory where you run the srsepc command or somewhere else?
Many Thanks,

Hi,
Right now I am running a 5 MHz LTE cell on my LimeSDR mini and RasPi 4, and my UE (a cheap Mediatek China phone) is logged in, has internet, and runs stable for the last 15 minutes now. Latency from the RasPi to the UE is between 20 and 32 ms, packet loss very low to nil, and a RoIP application (can be compared with Zello, but connecting to a real digital voice radio network) is running fine over this connection. The used source is from the pr_tinyrfci branch, but I will switch back to master, recompile and verify if this works, too.
