[Zavy86]

Hi, I'm trying to connect with a lwt on a ESP8266-01 but it doesen't work.

// definitions
const char* dev_hash="client";
const char* mqtt_hostname="192.168.1.10";
const char* mqtt_username="username";
const char* mqtt_password="password";
const char* mqtt_topic_lwt="/relays/lwt";
const char* lwt_message="offline";

// work
client.connect(dev_hash,mqtt_username,mqtt_password)

// doesen't work
client.connect(dev_hash,mqtt_username,mqtt_password,mqtt_topic_lwt,0,true,lwt_message)

Hi, solved increasing MQTT_MAX_PACKET_SIZE.
It is also possibile to increase without modify the PuSubClient.h file? like a parameter?
