how the iot clouds connecting to the client over dynamic ip
I read that many of the iot clouds are using MQTT protocol . If so to receive message from cloud to the device(iot gateway device such as esp8266 based device) will the iot gateway device need to connect with the cloud all the time?
or will it automatically connect when user send a message from his mobile app (similar to gcm) ?
as Iam not that much familiar In with this protocol side so am not getting the correct idea from internet if possible anybody please give the idea about how the cloud locate the device how it work on dynamic ip conditions ?
