Debugging complex embedded systems in the field requires more than just local logs and JTAG probes. To maintain visibility across a scaling fleet, engineers need robust cloud-based observability. This guide explores the integration of Spotflow with the Zephyr RTOS on an NXP FRDM-MCXN947 board. Learn how to configure your development workspace, navigate common Python versioning hurdles, and establish a secure MQTT connection. Follow along as we bridge the gap between local firmware execution and remote telemetry, setting the foundation for true fleet-wide monitoring and proactive system management.

Spotflow is an observability platform designed to bring cloud-style monitoring to embedded devices. This walkthrough covers setting up Spotflow with Zephyr RTOS on an NXP FRDM-MCXN947 board, including installing the MCUXpresso toolchain, resolving a Python 3.14 compatibility issue (downgrading to 3.12 fixes it), configuring Ethernet connectivity, and establishing a secure MQTT/TLS connection to the Spotflow cloud dashboard. After connecting the board to a network via Ethernet, the device successfully registered with Spotflow and began transmitting logs remotely. A follow-up article will cover integrating Spotflow into a custom Zephyr project for real telemetry collection.
