Solving NAT Timeouts for IoT Devices with Connection IDs

Network Address Translation (NAT) timeouts frequently interrupt IoT device-cloud communication, necessitating frequent reconnections and wasting resources. This post demonstrates how Golioth leverages DTLS 1.2 Connection IDs to mitigate this. By configuring the Golioth firmware SDK to disable keep-alive messages and set appropriate receive timeouts, coupled with Connection IDs, devices maintain connectivity even after NAT timeouts without costly handshakes, reducing power consumption and improving efficiency. This is particularly crucial for battery-powered, low-power devices.
