A stripped down garagedooropener crashes after first config via integrate AP. I set the MQTT port and after joining the WIFI the ESP Crashes:

The line is

601 boolean PubSubClient::connected() {
602     boolean rc;
603     if (_client == NULL ) {
604         rc = false;
605     } else {

Which is interesting - As _client is a private object pointer in the PubSubClient Class it seems there is no PubSubClient object instantiated or the pointer is NULL.

And no there is not a valid MQTT endpoint configured and yes i have increased the MAX packet size in MQTT.

Hi, i guess this is broken - mqttClient can be zero - So calling mqttClient->connected() causes the above crash.

 338                 wifiFailuresCount = 0;
 339 
 340                 if(!mqttClient->connected()) {
 341                         yield();
 342                         if(!connectToMQTT()) {
 343                                 mqttFailuresCount++;
 344                         }
 345                 }
 346 
 347                 if(mqttClientActive) {
 348                         mqttFailuresCount = 0;
 349                         yield();

With this fix it at least does not crash anymore. It comes up and falls back to config mode as there is no mqtt hostname:

 340                 if(mqttClient) {
 341                         if(!mqttClient->connected()) {
 342                                 yield();
 343                                 if(!connectToMQTT()) {
 344                                         mqttFailuresCount++;
 345                                 }
 346                         }
 347 
 348                         if(mqttClientActive) {
 349                                 mqttFailuresCount = 0;
 350                                 yield();
 351                                 mqttClient->loop();
 352                         }
 353                 }
