Hi,

Thank you for this information. It is great to hear that everything went well with your certification testing.

Best regards,

Just so others are aware, the certification test lab was able to perform both conducted and radiated tests with their callboxes without us having to make any changes. So using the Nordic LTE connection manager in the SDK does not appear to impact the basic signaling tests required for Regulatory (ex: FCC, CE mark) or Industry (ex: PTCRB, GCF).

So far so good with our testing.

Hi,

There are 2 guides that might be of interest to you:

Using nRF9160 against R&S CMW500 (or CMW290) in signaling callbox mode

Using the nRF9160 against Anritsu MT8821C In Signaling Callbox Mode

Hi,

[quote user="RileyH"]

Regarding the comment above (" up to the application to have a "test mode". If test-SIM is used and there is a need to test carrier specific feature") - Let me clarify, we are not trying to test a "carrier" (aka MNO) specific feature. We are needing to test industry standard test cases needed for Regulatory (ex: FCC) and Industry (ex: PTCRB) certifications. It's pretty basic testing that all nRF9160 customers will need to do. It's not some abstract MNO feature we are trying to test here.....

Our application makes use of the Nordic LTE connection manager and the MQTT client. It's all pretty much 'under the hood' to us so that's why I have posted the question. I wanted to know how your helper agents/services would handle these common test scenarios before starting to add a special 'test mode' which would require more work. I also dislike 'test modes' because it sort of invalidates the testing that needs to be done on the hardware/software to be commercialized). I had thought many others would have gone down this road before. Maybe I am concerned over nothing..

In the absence of information, I have sent a test sample device to the lab and asked them to run some quick tests required for FCC/RSE and PTCRB/OTA (TIS/TRP). I am also hoping that the Nordic AT command set has the additional capabilities needed for RSE tests. I am sort of assuming it does otherwise many other customers would have ran into this issue as well.

Could you please inform me if you need any further information other than what was provided previously?

[quote user="RileyH"]Stay tuned and thanks for asking [/quote]

I hope everything is progressing well with your certification testing. Please keep me updated on the status of your certification testing, and do not hesitate to ask if you have any further questions.

Best regards,
Dejan

Hi,

Could you provide an update on the current status? Were you able to proceed with certification testing in the lab?

Best regards,

Hi,

The proper behavior of not starting default PDN Connection immediately is up to the application to have a "test mode". If test-SIM is used and there is a need to test carrier specific features, then AT%XOPCONF is needed to enable specific carrier profile.

One possible problem for RSE and OTA testing could be that the application in use tries to send some data and tester (like CMW-500) is not configured to receive and respond to this data, but usually RSE and OTA testing are done with basic settings. From CMW-500 point of view, the modem should hold the connection as long as CMW-500 GUI option "keep RRC connection" is selected.

Dejan

Hi - I thought I would clarify my question in case it's not clear:

For FCC/PTRCRB type certification testing, my specific question is regarding the Nordic LTE link controller library and functionality.

My concern is that the Nordic LTE link controller might get ‘it’s knickers in a twist’ and create issues like continue scanning and dropping the CMW-500 connection. I am hoping that I don’t need to change the firmware on the device to accommodate the testing process. In a perfect world, those testing should be conducted with operational/commercial firmware and not ‘test code’.
