CC3220SF: Reading the SNR of wifi connection

Hey Raul,

Sorry for the late response here.

The CC32xx device cannot determine the SNR directly since it doesn't measure it directly.
However, it can measure the RSSI directly, and by measuring the noise value you can calculate the SNR value.

The uiSNRThreshold is a scan parameter within the API. Let's say for example that you perform a scan where the uiSNRThreshold is equal to a value of 10 dB. So the results of the scan will only include networks (APs when your device is set as a STA) with SNR value of at least 10 dB.
You can find more scan parameters here -> software-dl.ti.com/.../group__wlan__api.html

Yes, the Wi-Fi channel can be changed by:
1) Stopping the AP role.
2) Changing the channel via the configuration API.
3) Starting the AP role.

Hope this answer your needs by "intelligently".
Also, please refer to the CC3x20 Network Processor User's Guide where you can find further helpful information you'll might need -> https://www.ti.com/lit/ug/swru455m/swru455m.pdf?ts=1738053481862&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FCC3220SF

Let me know if you have further questions.

Best regards,
Omri
