Is it possible to attach button interrupts while wifi manager is active on configuration mode. I noticed that none of my buttons work when wifi manager is on configuration mode. How can i achieve this?

void configModeCallback (WiFiManager *myWiFiManager) {

Serial.println("Entered config mode");
Serial.println(WiFi.softAPIP());
//if you used auto generated SSID, print it
Serial.println(myWiFiManager->getConfigPortalSSID());
//entered config mode, make led toggle faster
ticker.attach(0.2, tick);
}

void setup() {
Serial.begin(115200);
Serial.println("Initialising");

pinMode(RELAY_PIN_01, OUTPUT);
pinMode(BUTTON_PIN_01, INPUT_PULLUP);

pinMode(RELAY_PIN_02, OUTPUT);
pinMode(BUTTON_PIN_02, INPUT_PULLUP);

pinMode(RELAY_PIN_03, OUTPUT);
pinMode(BUTTON_PIN_03, INPUT_PULLUP);

pinMode(LED_PIN, OUTPUT);

Serial.println("Enabling touch switch interrupt");
attachInterrupt(digitalPinToInterrupt(BUTTON_PIN_01), buttonChangeCallback_01, CHANGE);
attachInterrupt(digitalPinToInterrupt(BUTTON_PIN_02), buttonChangeCallback_02, CHANGE);
attachInterrupt(digitalPinToInterrupt(BUTTON_PIN_03), buttonChangeCallback_03, CHANGE);

MQTT_PORT = atoi(PORT);
WiFiManager wifiManager;
wifiManager.setAPCallback(configModeCallback);

// wifiManager.resetSettings();
wifiManager.setBreakAfterConfig(true);
wifiManager.setConfigPortalTimeout(180);

if (!wifiManager.autoConnect(deviceName, "12345678")) {
Serial.println("failed to connect, we should reset as see if it connects");
setup();
}

ticker.detach();

Serial.println("MQTT IP ADDRESS: \n");
Serial.println(MQTT_SERVER);
Serial.println("MQTT PORT: \n");
Serial.println(MQTT_PORT);

Serial.println("MQTT USERNAME: \n");
Serial.println(mqttUser);
Serial.println("MQTT PASSWORD: \n");
Serial.println(mqttPassword);
Serial.println("Device Name: \n");
Serial.println(deviceName);
Serial.println("Controller Topic: \n");
Serial.println(controllerTopic);
Serial.println("Device Topic: \n");
Serial.println(deviceTopic);

Serial.println("Topics: \n");

Serial.println(controllerTopic);
Serial.println(deviceTopic);

Serial.println("Connected to Wifi!.. :)");

Serial.println("Local Ip");
Serial.println(WiFi.localIP());

client.setServer(MQTT_SERVER, MQTT_PORT);
client.setCallback(MQTTcallback);

}

use non blocking mode, available in development branch

wm stable is blocking loop for webserver
