In this video, we will talk about Keep Alive and Client Takeover in MQTT *** Overview *** Keep Alive and Client Takeover are two concepts to circumvent the "half-open TCP Connection" state. Although MQTT is a very reliable and secure way to transfer data, it still can happen that the transfer between communication parties gets out of sync. If an MQTT client disconnects ungracefully and the MQTT broker is not notified, and is still under the impression of an existing TCP connection, the half-open TCP connection scenario occurs: one client disconnected, the other client is not aware of this.
