Combined WiFi and BLE Radio testing for nRF7002DK

[uh-ashishlele]

Hello,

We are in certification stages for our custom product based on the nRF7002DK. Our application requires BLE and WiFi to be operational simultaneously. Consequently, the certification process also requires capability to test both WiFi and BLE radio simultaneously.

We have been referring to the existing separate nordic samples for BLE and WiFi radio tests but unable to find a sample/ guide which can make both work as part of the same application.

Is there any way to achieve this where the radio tests can be performed simultaneously for WiFi and BLE through a common build?

Thanks,

Ashish

Hello Håkon,

In continuation to the certification tests that we need to support, the next test has the following high-level requirements:

1. DUT connects to a WiFi network
2. Test equipment/ WiFi sniffer will scan for the WiFi advertised by the DUT and connect to it
3. Configuration will be performed on the DUT related to IPV4/IPV6 interfaces i.e., different combinations of IPV4 and IPV6 enabling/ disabling

Is there a sample to support tests as per the above requirement? This is the test specification for your reference RFC 4213:2005, 2460:1998, 8200:2017

Please see this section of the previously linked application note:

Did you read my former comment on this matter?

Unfortunately, there is no direct command in the network shell to take down ipv4/ipv6, but you can add or remove IP addresses, for instance:

net ipv4 del index ip

ie.

net ipv4 del 1 192.168.1.x

 

Where '1' is the index, and 'xx.yy.zz.xx' is the IP assigned. You will then need to add it manually again:

net ipv4 add 1 ip mask

 

Similar with ipv6.

I am not sure why you are referring to these RFCs:

This is the test specification for your reference RFC 4213:2005, 2460:1998, 8200:2017

These RFCs are for describing IPv6 implementation in general.

What specifically are you testing? Is this a specific test case with teleregulatory requirements, and if yes; can you please share the test case?

 

Kind regards,

Håkon

Hi Håkon,

We have built an application to connect to a WiFi network and add/ delete a particular ip.

The part we're blocked on is that the device also needs to broadcast so that the test equipment can connect to it over WiFi. Is this possible?

Mentioned the RFC 4213:2005, 2460:1998, 8200:2017 since the test cases for the certification are based on these.

As mentioned, these RFCs are defining IPv6 in general, no need to point to them. Please rather point to the type of test case that you are trying to satisfy/test for.

Are you using SoftAP in your product? Usually one tests the STA (station) features, and the tester is then the access point (AP). Can you please point to what teleregulatory you are testing for? and which part of the specification of the teleregulatory?

 

Kind regards,

Håkon

Hello Håkon,

We need to fulfil the below clauses from Essential Requirements No.TEC24492408 from TEC, India

Please let me know if this information is sufficient.

Ashish

Hi,

 

Can you please share the .pdf for the specific document?

I have tried for the last half hour, but I am unable to load the website.

 

Kind regards,

I have this version (attached) . The clause numbers seem to differ but you can check by the parameter name/ standard name in column 2 and 3 respectively

Thanks,

Ashish.
