nRF7002 Roaming configurations and SNR level

[djgj]

Hello,

   We are using nRF7002 with RT555 in our product. We use zephyr 4.0.0 in our firmware.

we would like to know the if we can get the following info regarding nRF7002 usage for one of our customers.

We see that basic roaming is supported in nRF7002 as mentioned here: https://docs.nordicsemi.com/bundle/ps_nrf7002/page/chapters/functional/doc/sw_stack.html.

* Do you know if we can configure the roaming parameters like RSSI threshold that should trigger the AP switch? if so, what other parameters are available for configuring roaming feature?

* Do you know, if there is a way to identify or view if an AP switch has happened during roaming?

* Also do we have a way to know the SNR or noise level during a connection from nRF7002? potentially looking for any utility shell command for this purpose.

Thanks for your support.

Regards,

Dhananjay

Hi, 

Roaming as a function currently needs to be achieved at the application level. The wi-fi driver will notify the disconnect event to the application which then needs to initiate a new connection to an appropriate AP from its allowed list. Wi-Fi connection details (including RSSI) can be queried by the application, and this is implemented in the Wi-Fi shell via the wifi status command.

 The API for Wi-Fi status query - https://github.com/zephyrproject-rtos/zephyr/blob/main/include/zephyr/net/wifi_mgmt.h#L181

Thanks Amanda,
So user have to implement their own logic and algorithm for roaming.
Can you also respond about SNR and noise level on nRF7002? Our customers are interested to know about these too.

Yes.

It's already shared in my previous reply, both shell command and the API (we expose only RSSI no the SNR).
