Overrides the IoT endpoint port to connect to.
The IoT endpoint port to connect to. Usually 8883 for MQTT, or 443 for websockets
Overrides all configurable options with respect to the CONNECT packet sent by the client, including the will. These connect properties will be used for every connection attempt made by the client. Custom authentication configuration will override the username and password values in this configuration.

Overrides how the reconnect delay is modified in order to smooth out the distribution of reconnection attempt timepoints for a large set of reconnecting clients.

Overrides the minimum amount of time to wait to reconnect after a disconnect. Exponential backoff is performed with controllable jitter after each connection failure.
Optional
minReconnectDelayMs: numberminimum amount of time to wait to reconnect after a disconnect.
Overrides the maximum amount of time to wait to reconnect after a disconnect. Exponential backoff is performed with controllable jitter after each connection failure.
Optional
maxReconnectDelayMs: numbermaximum amount of time to wait to reconnect after a disconnect.
Overrides the amount of time that must elapse with an established connection before the reconnect delay is reset to the minimum. This helps alleviate bandwidth-waste in fast reconnect cycles due to permission failures on operations.
Optional
minConnectedTimeToResetReconnectDelayMs: numberthe amount of time that must elapse with an established connection before the reconnect delay is reset to the minimum
Overrides the time interval to wait after sending a CONNECT request for a CONNACK to arrive. If one does not arrive, the connection will be shut down.
Optional
connackTimeoutMs: numbertime interval to wait after sending a CONNECT request for a CONNACK to arrive

Constructs an MQTT5 Client configuration object for creating mqtt5 clients.
Overrides how disconnects affect the queued and in-progress operations tracked by the client. Also controls how new operations are handled while the client is not connected. In particular, if the client is not connected, then any operation that would be failed on disconnect (according to these rules) will also be rejected.

Overrides the time interval to wait after sending a PINGREQ for a PINGRESP to arrive. If one does not arrive, the client will close the current connection.
Optional
pingTimeoutMs: numbertime interval to wait after sending a PINGREQ for a PINGRESP to arrive
Overrides the time interval to wait for an ack after sending a QoS 1+ PUBLISH, SUBSCRIBE, or UNSUBSCRIBE before failing the operation. Defaults to no timeout.
Optional
ackTimeoutSeconds: numberthe time interval to wait for an ack after sending a QoS 1+ PUBLISH, SUBSCRIBE, or UNSUBSCRIBE before failing the operation
Overrides the socket properties of the underlying MQTT connections made by the client. Leave undefined to use defaults (no TCP keep alive, 10 second socket timeout).

Overrides (tunneling) HTTP proxy usage when establishing MQTT connections.
HTTP proxy options to use when establishing MQTT connections
Overrides additional controls for client behavior with respect to operation validation and flow control; these checks go beyond the base MQTT5 spec to respect limits of specific MQTT brokers.
