Best (most power efficient) way to detect a specific SSID?
Posted: Fri Jul 22, 2016 12:11 pmIs there a simple way to test for the existence of a specific SSID? My concern is power consumption.
Currently I took an example that scans wifi id then steps through the list of those seen and checks for a matching string. http://www.esp8266.com/viewtopic.php?f=29&t=10888
But it occurs to me that there may be some way to check just for a given SSID such as some kind of wifi 'ping' or something similar. Again, my main concern is to reduce the power if scanning regularly.
