Sandra Capri, CTO of Ambient Sensors, writes about building a Bluetooth Mesh demo where a cellular-based Thingy91 unit acts as a bridge to the Golioth Cloud.
The ESP32 can be used as an AT modem. This approach makes it really easy to add an internet connection to devices that normally don't have one, like the Nordic nRF52840DK.
Golioth introduced a new CircuitPython SDK to allow engineers to quickly prototype hardware that can talk to the Golioth cloud. By clicking "save" and having their CircuitPython recompile on the fly, they can try new hardware quickly and efficiently.
