- Tue May 19, 2015 10:22 pm #17917 I would like the ESP8266 module to connect up to multiple Access Points but don't want to send the SSID/password every time. I hope ESP8266 can remember as many SSID/password as possible. May I know how many SSID/passwords can ESP8266 store?

- Thu May 21, 2015 6:08 am #18050 It is all in the SDK Programming Guide PDF starting on page 34 (SDK v1.0.1).

Max of 5.

wifi_station_ap_number_set

Code: Select allFunction: 

Sets the number of APs that will be cached for ESP8266 station mode. Whenever ESP8266 station connects to an AP, it keeps caches a record of this AP's SSID and password. The cached ID index starts from 0.
   This configuration will be saved in flash system parameter area if changed.
Prototype: 

bool wifi_station_ap_number_set (uint8 ap_number)

Parameters: 

uint8 ap_number: the number of APs can be recorded (MAX: 5)
Return:

true: succeed
 false: fail

wifi_station_get_ap_info

wifi_station_ap_change

wifi_station_get_current_ap_id

Thanks. Can the maximum number of APs that can be cached be increased further? Can the code for the SDK be modified to raise the maximum?

those according to some schema. Scan for available APs, lookup data and configure it.
