I think @golioth.io may be the first custom Brick in @officialarduino.bsky.social App Lab πŸ‘€

We make use of both the BLE and Wi-Fi connectivity on the UNO Q to proxy data for BLE peripherals, stream data from attached sensors, and perform network-based positioning with Golioth Location!

Signed URLs on ESP32 This week we released v0.2.0 of signy, which expands support beyond Zephyr RTOS to Espressif's ESP-IDF. In addition to bringing signed URLs to more embedded devices, ESP-IDF support is particularly us...

We just released v0.2.0 of signy, our signed URLs library for embedded devices! This release includes support for ESP-IDF, which enables some new interesting use cases, such as leveraging the esp_http_ota component for OTA firmware updates from @golioth.io.

My UNO Q board arrived yesterday and it took only a few minutes to get up and running with an application that communicated with Golioth over Wi-Fi. I can’t think of a better development kit to demonstrate the flexibility of the Golioth platform!
