Arduino MKR1000 as Access Point

Question

I want to turn my Arduino MKR1000 into an Access Point. My code is the following:

#include <SPI.h>
#include <WiFi101.h>
#define PubNub_BASE_CLIENT WiFiClient
#include <PubNub.h>
WiFiServer server(80);
char ssid[] = "MKR1000";
int status = WL_IDLE_STATUS;
void setup() {
 delay(1000);
 Serial.begin(9600);
 Serial.print("Creating access point named: ");
 Serial.println(ssid);
 if (WiFi.beginAP(ssid) != WL_CONNECTED) {
 Serial.println("Creating access point failed");
 while (true);
 }
 server.begin();
 printStatus();
}
void loop() {
}
void printStatus() {
 Serial.print("SSID: ");
 Serial.println(WiFi.SSID());
 IPAddress ip = WiFi.localIP();
 Serial.print("IP Address: ");
 Serial.println(ip);
 long rssi = WiFi.RSSI();
 Serial.print("signal strength (RSSI):");
 Serial.print(rssi);
 Serial.println(" dBm");
 Serial.print("To connect, join the network and open a browser to http://");
 Serial.println(ip);
}

After uploading this, in the serial monitor I get this:

Creating access point named: MKR1000
Creating access point failed

I'm new to this so I really don't know what's the problem. I hope someone knows what's going on.
Thank you in advance.

• Chris Stratton: Hopefully you mean you want the board to function in AP mode for connected clients to exchange messages specifically with it. Trying to actually make it a wifi access point in the sense of a wifi router is not a viable idea.
• user9026955: Yeah sorry, that's what I meant.

Answer 1

I found this reference for Wifi.beginAP() in the Wifi101 library, which I hope is the correct one - apologies if it's not.

It says that beginAP() returns either WL_AP_LISTENING or WL_CONNECT_FAILED, so checking for WL_CONNECTED is not sensible.

Try this:

if (WiFi.beginAP(ssid) != WL_AP_LISTENING) {
 Serial.println("Creating access point failed");
 while (true);
}
