Hi,
I guess you have modified the library a little bit
For your information, the provided examples are only for station mode for ESPWiFi shield. Therefore by default, the shield is set to station mode, which allows only connection to other access points.
The library is still under development. However we have added softAP configuration into library and also example sketch of using softAP. You can download the latest library and try it.
Next time if you do want to enter some customised AT command in which this library doesn't support, you can just use print() function. For example,
wifi.println(your AT command); // enter your desired AT command
delay(100); //give some delay for full response
while(wifi.available()) {
Serial.write(wifi.read()); // show response on Serial monitor
}
You can try it out. Feel free to test and give us feedback and suggestions on library provided so we can make improvements.
Hope it helps!
