Easy Solutions for Cloud Connectivity for Embedded Systems

·24 min·2 clips

In 2003, Todd Baker struggled to connect a truck tracking system with a flip phone and a Sprint module.

A truck-tracking problem sets up the episode. The host remembers a 2003 or 2004 Austin design project where a major shipping company wanted live data from trucks that were always moving. The ask was concrete: tire temperature, tire pressure, rotation, movement, and a server-side data path using the cellular options of the time. That was not a quick hookup. A Sprint cellular module, a custom server, and a strong engineering team became the working answer because the ecosystem around embedded connectivity was still rough. The episode uses that old project as a before-and-after for embedded design. Hardware engineers may already be comfortable with controllers, sensors, and serial communication, but getting that data all the way to a server used to be the part that ate time. The host keeps coming back to time-to-market: FCC certification delays, missed windows, and competitors getting something like six months of breathing room. The guest makes the newer approach feel less theoretical by describing a microchip and uBlock solution from the FCS team, starting with a board sitting on his desk. He names an AVRBLE board, mentions that a PIC version exists, and walks through Bluetooth Low Energy, Wi-Fi, and a uBlock SARA R4 cellular module as the pieces doing the work. The sensor example helps: accelerometer and temperature data can move from a microchip board over Bluetooth and then out through cellular. The point is less workload, not magic. Server connectivity no longer has to become a custom infrastructure project every time. Packaged radios, reference hardware, and engineering help can take a lot of risk out of the design. The close keeps that practical tone, pointing listeners to linked videos and an email contact while framing the FCS and advanced engineering teams as useful backup for engineers trying to ship connected products.

As heard by us

A practical path from embedded sensors to cloud-connected hardware, with the hard parts still clearly in view.

A working engineer's memory of a fleet-tracking build gives the conversation its shape, moving from early-2000s cellular, custom servers, and the hard work of making truck data visible.
