The ESP32 and the product line variants often run Bluetooth alongside Wi-Fi. This post shows how you can use the Bluetooth capabilities of an Espressif chip to talk back to the internet when a Wi-Fi signal isn't the right fit for your application.
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.
Uploading audio from IoT devices to the Cloud is easy with Golioth. Here's everything you need to know to deliver large chunks of data from your fleet to whatever cloud service you desire, all with just one API call and one callback function.
This post walks through how to upload images from IoT devices to Golioth over CoAP using block upload. Once the image is at the server, Golioth Pipelines can route the data to the destination of your choice!
You can use VScode when working with Golioth's ESP-IDF SDK. This guide walks through the process of setting up the ESP-IDF extension for VScode, then shows how to build, flash, and run the golioth-basics example application.
