Connection Management

AdafruitMQTT can connect to an MQTT broker using both 'open' (unencrypted) or 'secure' (TLS/SSL encrypted)

connections.

bool connected(void)

Indicates if we are currently connected to the MQTT broker or not.

Parameters: None

Returns: 'True' (1) if we are connected to the MQTT broker, otherwise 'false' (0).

bool connect ( IPAddress ip, uint16_t port = 1883, bool cleanSession = true, uint16_t

bool connected ( void );

bool connect ( IPAddress ip,

uint16_t port = 1883,

bool cleanSession = true,

uint16_t keepalive_sec = MQTT_KEEPALIVE_DEFAULT);

bool connect ( const char* host,

uint16_t port = 1883,

bool cleanSession = true,

uint16_t keepalive_sec = MQTT_KEEPALIVE_DEFAULT);

bool connectSSL ( IPAddress ip,

uint16_t port = 8883,
