Golioth Connectivity enables developers to connect Bluetooth devices to the cloud using Gateways, including microcontroller based gateways. Today we’re discussing the Globalscale GTI-RW612 gateway. It’s an off-the-shelf piece of hardware normally marketed at the Matter ecosystem, but has been repurposed for Golioth Connectivity. We’ll show how we got it working sending Bluetooth device data to the Cloud and discuss the application spaces where this gateway might be a good fit. About the GTI-RW612 and NXP RW612 Chipset We are big fans of NXP parts, including the tri-band radio on the RW612. We have precompiled Bluetooth gateway binaries for the FRDM-RW612, which is an affordable dev board from NXP and a super easy way to get started with Golioth Connectivity. You can route Pouch-based Bluetooth packets back to the cloud using either Ethernet or Wi-Fi. This chip is targeted at the Thread / Matter ecosystem as a Border Gateway all-in-one chip, and it hits the mark. Each of the radios have a dedicated memory space and there is an additional Ethernet interface to enable wired backhaul. The main application processor is built with a core of a Cortex M33, but running at a whopping 260 MHz! There is also a PowerQuad coprocessor, but honestly we haven’t scratched the surface at utilizing all of the capabilities on this chip yet. Globalscale took this part and created their own in-house module, the GTI-RW612B. Though the name is a bit confusing (similar to the name of the gateway that employs that module), the idea is clear: this is a module that enables precertified access to a capable chipset. The GTI-RW612 is the gateway itself, targeted at the Matter market as a border router. The…
