ESP8266WiFi extended functions

begin changes
allow setting BSSID/MAC and Channel of an AP for faster connection (#261)
now checks if ssid and passphrase to big
selecting Wifi mode in better way (fix for #28)

ESP8266WiFiMulti uses the new functions to auto select best AP even in a multi AP WiFi network (more the one AP has same SSID)

add new functions to get current Connected AP:
uint8_t * BSSID(void);
int32_t Channel(void);

add new functions to get infos from scanned networks:
uint8_t * BSSID(uint8_t networkItem);
int32_t Channel(uint8_t networkItem);
bool isHidden(uint8_t networkItem);
bool getNetworkInfo(uint8_t networkItem, const char** ssid, uint8_t * encryptionType, int32_t * RSSI, uint8_t ** BSSID, int32_t * channel, bool * isHidden);

Have just cloned and build from source 1.6.5, loaded the WiFiScan example and I get the following error when I try to compile:

WiFiScan.ino: In function 'void loop()':
WiFiScan:38: error: 'class ESP8266WiFiClass' has no member named 'BSSID'
'class ESP8266WiFiClass' has no member named 'BSSID'

Same here, can't use the BSSID atm.

can you please check if
https://github.com/esp8266/Arduino/blob/esp8266/hardware/esp8266com/esp8266/libraries/ESP8266WiFi/src/ESP8266WiFi.h#L214
and
https://github.com/esp8266/Arduino/blob/esp8266/hardware/esp8266com/esp8266/libraries/ESP8266WiFi/src/ESP8266WiFi.cpp#L347
are in you locale files.

Also check if you have the board manager package installed. You need to uninstall it if you have because it overrides any cores bundled with the app.

Let me try some telepathy... did you replace Serial.print(WiFi.RSSI(i)); with Serial.print(WiFi.BSSID(i)); in your sketch? This is not valid code...

[kgolding]

igrr yes! Sorry!

have add some functions to get the MAC / BSSID as string.

For those like I who want to convert the WiFi.BSSID() result to a string, I've created the following function (inspired by @Links2004 functions):

String bssidToString(uint8_t *bssid) {
  char mac[18] = {0};
  sprintf(mac,"%02X:%02X:%02X:%02X:%02X:%02X", bssid[0],  bssid[1],  bssid[2], bssid[3], bssid[4], bssid[5]);
  return String(mac);
}

This can be called using:

Serial.print(bssidToString(WiFi.BSSID(i)));

@kgolding great function. Best answer. Thanks
