Hello.

I`m trying to use ESP ID as WIFI name and custom password but getting error:
exit status WiFiManager::autoConnect(String, String)

Here is a part of code:

#define AP_SSID "ESP8266-"
#define AP_PASSWORD_PREFIX "SECRET" // + mac XXXX
#define AP_PASSWORD_SUFFIX "PASS"

String AP_Name = "";
String AP_Pass = "";
// skip
Serial.println(AP_Name);
Serial.println(AP_Pass);
if(!wifiManager.autoConnect( AP_Name,AP_Pass)) {
Serial.println("failed to connect and hit timeout");
//reset and try again, or maybe put it to deep sleep
ESP.reset();
delay(1000);
}
// skip
// ----------------------------------- createAPNameandPass -----------------------------------
void createAPNameandPass() {

//Serial.println();

uint8_t mac[WL_MAC_ADDR_LENGTH];
WiFi.softAPmacAddress(mac) ;
String APmacStr;

APmacStr = String(mac[WL_MAC_ADDR_LENGTH - 6], HEX) + ":" +
String(mac[WL_MAC_ADDR_LENGTH - 5], HEX) + ":" +
String(mac[WL_MAC_ADDR_LENGTH - 4], HEX) + ":" +
String(mac[WL_MAC_ADDR_LENGTH - 3], HEX) + ":" +
String(mac[WL_MAC_ADDR_LENGTH - 2], HEX) + ":" +
String(mac[WL_MAC_ADDR_LENGTH - 1], HEX);

String APmacID = "";

if (mac[WL_MAC_ADDR_LENGTH - 2] < 0x10) APmacID = APmacID + "0";
APmacID = APmacID + String(mac[WL_MAC_ADDR_LENGTH - 2], HEX);

if (mac[WL_MAC_ADDR_LENGTH - 1] < 0x10) APmacID = APmacID + "0";
APmacID = APmacID + String(mac[WL_MAC_ADDR_LENGTH - 1], HEX);

APmacStr.toUpperCase();
APmacID.toUpperCase();

AP_Name = AP_SSID + APmacID;
AP_Pass = AP_PASSWORD_PREFIX + APmacID + AP_PASSWORD_SUFFIX;

Serial.println ("");
Serial.print("AP SSID: "); Serial.println(AP_Name);
Serial.print("AP pass: "); Serial.println(AP_Pass);

Serial.print("AP MAC address: ");
Serial.println(APmacStr);

}

Where is my mistake ?
