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.
Zephyr is one of the fastest-growing RTOS ecosystems in the embedded world—but getting started can be overwhelming. That’s why Golioth offers free Zephyr training sessions every quarter: 3 hours of expert-led, hands-on learning designed to jumpstart your development. Our next training is June 25th, 2025...sign up today!
Sign up for the AirTag Clone webinar series to watch Golioth build out board definition files for the Orleon board, a Bluetooth sensor platform/playground. The upcoming session on May 23rd will walk through setting up all required build files.
Fuel gauge ICs offload effort when it comes to taking reliable battery readings and estimating charge and drain times. Zephyr's support for these components makes using them even easier.
Sniffing network packets from a cellular modem is actually pretty easy. It only seems daunting because at first glance you're left wondering how to acquire the packets. Nordic's nRF91 modems have a trace capability that can be used to pipe packets from the device into Wireshark over a USB connection. Here's how to use it.
The SIMCOM SIM7080G is a Cat M1 / NB-IoT modem that focuses on low power applications. We tested out the modem using Zephyr's subsystem to connect to the Golioth Cloud.
