Using nRF9160 on R&S CMW5009160-CMW500 signaling callbox ,not about to establish connection

[Oscar Chung]

We are now facing a difficulty making a continuous connection between the Rohde & Schwarz CMW500 equipment and devices with the Nordic nrf9160 module(including one Development Board of Nordic nrf9160 in our hands right now).

We did tests by following some Instructions earlier today but couldn’t make it. Here I put many videos and documents in below shared link as our record of what have done: https://workdrive.zohoexternal.com/external/3fb20a15f40dbc8f497e2726b66462155fa9b00bd54bbf51215fc39c623867c0

For an easier reference. There are a total 9 files in that shared folder,pls check. 

1. First of all, we have configured many items/points on the CMW500 as “Follow the Guide in Nordic webpage to configure the CMW500.jpg” indicated, failed. 

2. After that, we tried to use these .dfl files “M1 configuration file for signalling.dfl“、”DAU-NB1-M1.dfl“、”M1dataCMW500.dfl“ to configure the CMW500 directly, as those video files showed but still failed.

    It returned ”RRC Reconfiguraton Failure” by system.

 Do you have any Detailed Instruction about how to configure equipment like that CMW500 series for Nordic module? With some Video Instruction that would be much helpful.

If you have, can you pls share it with us? Thank you very much.

Hello Oscar,

I've managed to find a brief that was created some time ago by Nordic that was useful for my own steps. I've attached the pdf here.

What I saw as I went through it was that there was two steps that made a difference in order to get the attached state and stay there.

CMW500_Test_Setup_Instructions_v1.0.0.pdf

1. AT client FW running on the device.
2. XSYSTEMODE setting. My test setup was for LTE-M1, but initially my config had NB-IOT only and not enable LTE-M, so i didn't get the attach.  See link to docs.nordicsemi.com below

3. eMTC Auto Mode to RMC setting shown in the pdf attached was also incorrectly set on my CMW and that from eMTC Auto Mode to RMC setting made a difference.
4. I also set up to start with band 1 for my test and didn't try starting with any other band setting.

Best regards
