Command to view signal strength or available AP's

By heckler
- Sat Dec 19, 2015 11:24 am #36788 Is it possible to view wifi signal strength or list available AP's (CWLAP) been implemented in the Basic OS??
How about being able to view connected clients to the ESP module with the (CWLIF) command??

AT+CWLAP - Lists available APs
AT+CWLIF - List clients connected to ESP8266 softAP


Thanks!!

I guess you could check for open connections with one of these and a small screen make your own wifi scanner but doubtful it will be as good as what is listed above.

Would be interesting to scan and have a drop down menu on the settings page with a button to scan so it does not constantly scan to me not important though ... To others maybe but if you are accessing the esp you are going to have to know something about your network I presume.

I would like to see the ability to change the AP IP personally when talking of changing wireless settings.

Interesting request I am a bit curious as to the reasoning behind the request maybe it is something I am missing?

Returns number of available networks.
wifi.scan()

Returns SSID string (Network name)
wifi.ssid({value or var for number})

Retuns signal Strength:
wifi.rssi({value or var for number})

This code will list access points and there signal strengths.
Code: Select alln = wifi.scan()
html "Number of network found = "
html n

for x = 1 to n
html "<hr>"
html wifi.ssid(x)
html ","
html wifi.rssi(x)
next x
