Esp8266 - Long time to establish connection to AWS and messages each second. about aws-mqtt-websockets HOT 2 OPEN

Hi! I didn't have this 5 minutes to connect issue. I will try to observe my example to see if this happen.

about the message every 15 seconds, this is the ping message from the mqtt protocol to keep the connection alive. you can configure it, as you did directly in the pubsubclient file.

about the AWS keepalive configuration (search keep-alive-interval) https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html

For MQTT (or MQTT over WebSockets) connections, a client can request a keep-alive interval between 30 - 1200 seconds as part of the MQTT CONNECT message. AWS IoT starts the keep-alive timer for a client when sending CONNACK in response to the CONNECT message. This timer is reset whenever AWS IoT receives a PUBLISH, SUBSCRIBE, PING, or PUBACK message from the client. AWS IoT will disconnect a client whose keep-alive timer has reached 1.5x the specified keep-alive interval (i.e., by a factor of 1.5).The default keep-alive interval is 1200 seconds. If a client requests a keep-alive interval of zero, the default keep-alive interval will be used. If a client requests a keep-alive interval greater than 1200 seconds, the default keep-alive interval will be used. If a client requests a keep-alive interval shorter than 30 seconds but greater than zero, the server treats the client as though it requested a keep-alive interval of 30 seconds.

Thanks @odelot for your response! Sorry for retard in my feedback! Your link maked the keep alive procedure very clear for me! My esp get 3 min for connection establish for begin, but after some resets it's taking some seconds to connecting.
