Hello,

I managed to achieve a successful cell attach and registration between a LimeSDR-mini acting as eNB and a LimeNET-micro acting as UE, both running on the same computer.  
Getting srsLTE to work was not easy, it seems a regression was introduced this year in the eNB codebase -producing SOAPY\_SDR\_TIMEOUT stream errors, so I had to use an earlier version of the code.

Software versions:  
SoapySDR - tag 0.7.1  
LimeSuite - commit 1b0309b385547db64ef116618c774c8ce62de0d5  
srsLTE - commit d045213fb9cbf98c83c06d7c17197a9dcbfddacf

Configuration: EARFCN was chosen within the amateur radio band 2305 - 2400 MHz.  
time\_adv\_nsamples was set to 70 for both eNB and UE.  
Number of PRBs selected for eNB was 15 to fit within LimeNET-micro USB2.0 bandwidth.

A minor patch was necessary for the Soapy driver of srsLTE. Unfortunately the default code does not allow us to choose between multiple devices so I made a 4 line hack to enable the UE to run on the same machine as the eNB:

```
diff --git a/lib/src/phy/rf/rf_soapy_imp.c b/lib/src/phy/rf/rf_soapy_imp.c

+ if (args && (strstr(args, "nextdev"))) {
+ sdr = SoapySDRDevice_make(&(soapy_args[1]));
+ } else {
+ sdr = SoapySDRDevice_make(&(soapy_args[0]));
+ }

- SoapySDRDevice* sdr = SoapySDRDevice_make(&(soapy_args[0]));
   if (sdr == NULL) {
     printf("Failed to create Soapy object\n");
     return SRSLTE_ERROR;

```

I should also mention that I keep getting an error that I did not manage to track yet from the eNB and UE to the tune of:  
[ERROR] Tx Calibration: MCU error 4 (SXT tune failed)

Thanks for sharing!

I wondered if you had tried with current srsLTE plus Lime Suite built from git master? I understand that there are some recent updates to Lime Suite which srsLTE use will benefit from. A new Lime Suite release is schedule for the end of the month and this should include these.

@zack may be able to say more on this.

Andrew, yes, I’ve tried and like I mentioned in the first post, the current srsLTE does not work with either SoapySDR 0.7 or 0.8 and the latest LimeSuite from master. The reason is stream timeouts and zero samples being transmitted.  
What works is srsLTE release 19.12 with latest LimeSuite from master and SoapySDR 0.7 (possibily also 0.8) using the patch above to enable more than one soapy device on the same computer. Anything later than 19.12 does not work, so a regression must have been introduced somewhere or some documentation is missing on their side.

I’d like your opinion about the two errors I still get, taken from logs above:  
[ERROR] Tx Calibration: MCU error 4 (SXT tune failed)  
[ERROR] Rx calibration: MCU error 3 (SXR tune failed)

What is the usual cause for these? I don’t see them in qradiolink for either device.

@andrewback I managed to reliably reproduce the above error:

```
[ERROR] Tx Calibration: MCU error 4 (SXT tune failed)

```

by removing some of the workarounds I put in my own code a while back.  
The issue occurs when trying to set up and start a Soapy TX stream while a Soapy RX stream is running. My workaround was to stop the RX stream during TX stream initialization, and it avoids this error. I’m not sure if this is a limitation or an actual issue.

Any experience using the limenet micro as a small BW eNB? For example only 15 or 6 PRBs? Even more - only in TX mode without RX? That is, only with PSS, SSS, CRS, MIB and SIBs?

Not aware of anyone having tried this. Should be possible with RPi 4, but obviously there is no CM4 to use with LimeNET Micro and if there was, it would need a PCB re-spin to route the additional lines for USB 3.0.

In any case, if you do try this, let us know how you get on. If you don’t have a LimeNET Micro yet, but do have a LimeSDR Mini, you could try this with an RPi 3B, which would be pretty much the same in terms of compute performance.

I wasn’t able to get an UE attach with either 6 or 15 PRBs (tried both). Keep in mind I didn’t use the latest version because I couldn’t get it to run with the Lime HW.  
Regarding the CM3, I’m a little skeptical because as far as I know the turbo decoder only has AVX not Neon optimizations. Maybe NB-IoT would be more realistic.

Thanks for the information!

A follow-up question. The turbo decoder is only for the uplink, right. I was thinking about its capability of only acting as a downlink beacon, transmitting PSS, SSS, CRS, MIB and SIB1. Anyone with any experiences there?

Hi. Do you mean getting latest version to work, or about using 19.12? I was having issues with the latest version which could have been due to some outdated system components, which I might have to investigate again after OS upgrade. Regarding my configuration files, I don’t know if they would be much use to you since I have since changed them trying to play with various settings.  
For the Lime hardware, though, this is the setting in enb.conf that I found useful to get it working. It is entirely empirical though and might vary from machine to machine:

```
time_adv_nsamples = 60
```
