actively trigger wifi scan

[37eex9]

Feature description

I'd like to have a termux-wifi-scan command to actively trigger the OS to start a wifi scan. This would make termux-wifi-scaninfo more powerful, as one could grant that the last scan happened in recent past. Currently, sometimes termux-wifi-scaninfo shows wifis I did not see for several minutes (up to 15 min).

Reference implementation

Have you checked if the feature is accessible through the Android API?

• in the Android API there is the startScan() method. It is deprecated since API 28, though I know it is used by some Wifi scanners, e.g. WiFiAnalyzer.
• I can only test it on Android 10 and for me it works. It seems like it is not yet removed from the Android API.

Do you know of other open-source apps that has a similar feature as the one you want? (Provide links)

• WiFiAnalyzer use it in Scanner.update().

I assume it is not very likely to add a feature based on a deprecated API call. Anyway, I think it is worth giving it a try.

Thanks in advance ;)
