Scanning for wifi signals only in 2.4Ghz band

Question

I need to scan for available Wi-Fi signals and their strengths. I\'m using wifiManager.startScan(); and asynchronous wifiManager.getScanResult();.

Answer 1

Is there any way I could tell the device to scan only in the 2.4GHz band

I think there is not way how to achieve it.

All you can do is only call startScan() and wait for results. Then you can filter results due to their frequency especially for 2.4Ghz frequency of each AP (Access Point) should be bellow 2500 Mhz.
