Bluetooth HCI enables any chipset to act as a peripheral to a processor running a Bluetooth stack. We pair the ESP32-C3 HCI with a processor running Zephyr to turn Golioth's development platform--the Aludel Elixir--into a Bluetooth gateway.
Here's how easy it is to add a Bluetooth device to the cloud. In just a few minutes, we built a BLE-GATT example for the Arduino Nicla Sense ME board and had it sending data to the cloud.
Robert Colvin from Telenor Connexion joins Golioth for a webinar coming up July 2nd, 2025. We will talk about how to troubleshoot cellular deployments and how you can apply some of the lessons learned to your own product.
Golioth makes it easy to connect Bluetooth devices to the cloud. Load provided binaries to create a Bluetooth gateway, then use reference Zephyr code to connect BLE devices from your fleet to the Internet. Here we show how to add an STMicroelectronics dev board as a leaf node in your fleet.
We implemented Golioth's Bluetooth-to-Cloud connectivity on a battery pack on a commercial power drill. We not only monitored power usage of the drill, we also looked up the location of the most recent gateway we connected through and attached that to the drill's device record.
Golioth's Bluetooth-to-Cloud is in private access currently, but this post lets you peer behind the curtain to see how it works on some development boards.
Have you ever wanted to build your own Apple AirTag? Join us for a free webinar series (starting April 11) where we walk through how to design and prototype a small, Bluetooth-enabled sensor device using Zephyr RTOS, the nRF52840, and Golioth's new Bluetooth-to-Cloud capabilities.
