Bluetooth Support is here: Golioth Connectivity enables a new class of devices

Golioth Bluetooth Support enables Bluetooth devices running Zephyr RTOS to communicate securely back through standard gateways to the Golioth cloud. This enables popular features such as streaming telemetry, OTA firmware updates, settings management, and event logs.

How to Flash a Pre-Loaded Filesystem During Production

Creating a filesystem separates your everyday firmware from other data like machine learning models, images, and binaries. In this post we discuss how you can set up the filesystem to speed up your production and create a flexible system that can be updated on-demand using Golioth's OTA service.

How to build a Bluetooth-connected digital signage fleet

Use Golioth Connectivity to create Bluetooth-enabled Digital Signage fleets. This demo shows how you can create an LED matrix that shows different informational callouts. We also show how you can easily provision a new device onto your fleet with certificates.

A Settings System for any Bluetooth Fleet

The Golioth settings service is now available via Golioth Connectivity, which supports Bluetooth devices. This allows you to send updates to all your devices, a subset, or a single device, just like other devices using the Golioth Firmware SDK.

Get started with Bluetooth and Golioth Connectivity

Golioth just announced Bluetooth Support...but how can you get started? This post walks you through the installation steps and has a signup for an upcoming livestream on August 29th where we'll go through the entire workflow together.
