## AI overview

This tutorial explains how to connect an ESP32 sensor to a cloud platform using a compact UDP datagram instead of the usual HTTP, JSON, and TLS approach. It presents TagoTiP, an open specification for structured IoT data, and describes frames of about 130 bytes with typed variables, units, device identification, and authorization information.

## Source excerpt

Connecting an ESP32 to a cloud platform usually means HTTP libraries, JSON parsers, and TLS handshakes. This tutorial shows a different approach: a single UDP datagram, built with snprintf, carrying structured sensor data in about 130 bytes. The TagoTiP open specification makes it possible by defining the data structure so you don't have to.
