## Summary

Chris Gammell, Developer Relations Lead at Golioth, explains how their platform simplifies IoT development by bridging constrained microcontrollers and the cloud using CoAP and Zephyr RTOS. He details the device-side SDKs for ESP32, nRF, and NXP, and discusses the business model of licensing the cloud software for on-premise deployment. The conversation also covers the shift in chip ecosystems, noting Espressif's move to RISC-V and the challenges of integrating Wi-Fi modules with low-power MCUs.
