Combined WiFi and BLE Radio testing for nRF7002DK

Hi,

Please read carefully what I stated in my former responses, and be sure to read both nAN46 and nWP-045 chapter-to-chapter. The answer to your questions are in those documents.

[quote user="uh-ashishlele"]Note: I could not find any reference of ETSI/FCC test cases in any of the requirements that I'm working with.[/quote]

It is clearly stated in my former link what test-cases are for each band:

[quote user="hkn"]

For instance, for ETSI you want to look at these compliance testing documents:

https://docs.nordicsemi.com/bundle/nan_046/page/APP/nan_046/regulatory_test_cases.html

[/quote]

You need to contact a certified test house to help you with this.

Kind regards,

Håkon

Hi,

I attached links for specific clauses rather than the entire RFC which need to be fulfilled to achieve compliance. The objective is to achieve compliance for the following:

Primarily - Fulfilment of TEC requirements.
The TEC requirements are clauses in the previously attached file TEC24492408_IoT.pdf
The clauses from the above mentioned document, in turn, resolve to the RFC Clauses which I have highlighted in my previous message.

Summarizing, the DUT needs to support the following to pass compliance:

Dual IP parameters
IPV4 parameters
IPV6 Dual stack parameters
IPV6 parameters

I want to understand whether a single sample application can be used to support the above tests. Please let me know if the details/ summary is still insufficient.

Note: I could not find any reference of ETSI/FCC test cases in any of the requirements that I'm working with.

Hi,

Please share the specific test cases in either ETSI/FCC for those specific tests. As previously mentioned; quoting/linking a whole RFC does not make sense in regulatory compliance testing.

You are basically stating that you require IPv4/IPv6 protocol support, which I have mentioned that the SDK supplies you with.

For instance, for ETSI you want to look at these compliance testing documents:

https://docs.nordicsemi.com/bundle/nan_046/page/APP/nan_046/regulatory_test_cases.html

[quote user="uh-ashishlele"]Would you able to guide on the best approach to support these tests? The DUT is a nRF7002DK based custom device and the lab normally uses an Alfa AWUS036ACH Wi-Fi adapter for monitoring[/quote]

Run any sample that has Wi-Fi station capabilities, as mentioned in the nAN-046, with a tester (access point):

https://docs.nordicsemi.com/bundle/nan_046/page/APP/nan_046/wifi_sta_sample.html

[quote user="uh-ashishlele"]the lab normally uses an Alfa AWUS036ACH Wi-Fi adapter for monitoring[/quote]

This is not a Wi-Fi 6 capable adapter.

What is your end-goal here? Everything you have shared of documents, like this:

[quote user="uh-ashishlele"]TEC24492408_IoT.pdf[/quote]

states that you want to do RF PHY related tests, ie. either FCC (for US) or ETSI (Europe), but you keep linking protocol implementations, which can indicate that you want to do Wi-Fi Alliance listing:

https://docs.nordicsemi.com/bundle/nwp_045/page/WP/nwp_045/intro.html

Do you need regulatory compliance testing (FCC/ETSI) or do you want to list your end product (Wi-Fi Alliance)?

Kind regards,

Håkon

Hello Håkon,

We have received a more detailed list from the lab regarding the RFC clauses for testing. The clauses are as below:

RFC-791 clause-3.1

https://datatracker.ietf.org/doc/html/rfc791#section-3.1

RFC 4213 Clause 2.1

https://datatracker.ietf.org/doc/html/rfc4213#section-2.1

RFC 2460/8200 Clause 3,4.1,4.4,4.5 & Annex to ER P7.1 to 7.8 & P7.11 -to P7.12

https://datatracker.ietf.org/doc/html/rfc2460#section-3

https://datatracker.ietf.org/doc/html/rfc2460#section-4.1

https://datatracker.ietf.org/doc/html/rfc2460#section-4.4

https://datatracker.ietf.org/doc/html/rfc2460#section-4.5

7.1 to 7.8, 7.11 and 7.12 https://datatracker.ietf.org/doc/html/rfc2460#section-3

Would you able to guide on the best approach to support these tests? The DUT is a nRF7002DK based custom device and the lab normally uses an Alfa AWUS036ACH Wi-Fi adapter for monitoring

Thank you,

Ashish Lele.

Hi,

Thank you for sharing the document.

These two columns specify parameters that are linked with the variant (ie. if LoRA, BLE, Wifi, fiber, etc) - so there seems to be a prerequisite that the device supports IPv4 and IPv6, which the network stack within zephyr does.

Interface 26 explains what is an added requirement for Wi-Fi and what specification is linked to that specific test-case(s). If you have a 3rd party module, they are usually ETSI/FCC precertified.

Kind regards,

Håkon

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

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.

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:

Hello Håkon,

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

DUT connects to a WiFi network
Test equipment/ WiFi sniffer will scan for the WiFi advertised by the DUT and connect to it
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

Hi Håkon,

For the WiFi radio test, there are additional requirements that need to be fulfilled for certifications, mentioned below:

Data rate configuration for WiFi - Ability to configure 1Mbit and 2Mbit
Modes configuration for WiFi as follows:
1. For 2.4 GHz
  1. B mode: data rate 1 and 11 mbps
  2. G mode - data rate 6 and 54 mbps
  3. N mode - data rate MCS0 and MCS7
  4. Channels 1 to 13 as per ETSI
2. For 5 GHz
  1. A, N, AC modes

Are the above requirements also supported?

Hey Håkon
We are not enabling both wifi/radio_test and interface testing simultaneously. We are trying to set up interface testing on an other device entirely.
I have used the wifi/sta sample and enabled some shell commands to set up ipv4/v6 conection.

I was looking for a way to dynamically(through RTT shell commands) disable and enable ipv4 or ipv6 as it is a testing requirement. ( RFC 4213:2005, 2460:1998, 8200:2017 )

Hi,

We need to setup framework for the following testing RFC 4213:2005, 2460:1998, 8200:2017 on our custom nrf7002_nrf5340. Is there an existing framework that can be used to carry out this testing?[/quote]

To test IPv4/v6, you can use any example that has it enabled, for instance wifi/shell.

[quote user="meraki"]The next step for us is interface testing. Where we need to obtain and display ipv4 and ipv6 address and want an interactive shell as well.
Was able to achieve this by adding necessary shell configs to wifi/sta sample. But we are facing the below error after receiving the connected status.

rtt:~$ [00:03:06.070,190] <dbg> net_icmpv6: net_icmpv6_input: (rx_q[0]): ICMPv6 Multicast Listener Query received type 130 code 0

Could you explain what was done specifically to get to this error message?

Please note:

You cannot enable both the wifi/radio_test and use STA/SoftAP simultaneously, unfortunately.

wifi/radio_test uses a specific test firmware that it loads to the nRF700x, which cannot be used simultaneously as the normal functions.
