Wifi + BLE
Duo contains both WiFi and BLE capabilities. You can build your project using either WiFi or BLE or both. They share the same 2.4GHz antenna and can run at the same time. This gives you the flexibility in utilizing the most suitable wireless technology(s) for your project.
Duo gives you four development platforms/languages to choose from:
Arduino IDE – Popular Development platform. Easy to learn.
Particle WebIDE – an online development platform allows you to program your Duo online. So, you can be miles away and still be able to do your tweaking of your Duo.
Broadcom WICED SDK – An advanced development platform where you can do low-level tweaking. With the WICED SDK, Duo can support Classic Bluetooth which you can build audio or streaming data devices. If you have Apple MFi license, you can even development your Apple HomeKit project with Duo and WICED.
We also provides many of sample projects, sample codes including Android and iOS. You can find them on our website or via GitHub.
Cloud – Particle Cloud
Thanks to our partner, Particle, every Duo will come with instantly ready Cloud service. Just with a few clicks from our Companion App, you will be connected to Cloud seamlessly. And not only that, the Cloud service is FREE for the lifetime of Duo. You can push any changes and data via Cloud right from the start.
Add-Ons – Grove Modules from Seeed
Coupling the Duo with RedBear RBLink, modules from the Seeed’s Grove System can easily be attached to your project. There is no need of any soldering work. Just attach with jumper connectors and you are ready to see result.
We don’t work alone. We connect with other IoT companies to bring Maker community better and better user experiences.
BlueKitchen – We are collaborating with BlueKitchen to integrate their BTstack with the our Duo.
BTstack is BlueKitchen’s implementation of the official Bluetooth stack. It is a dual-mode Bluetooth (BLE + Bluetooth Classic) stack, with small memory footprint and available as ANSI-C source code. BTstack is free for non-commercial use.
Blynk – You will enjoy 50% discount on a single purchase of Blynk paid services when they’re live.
Blynk is the most user-friendly mobile app constructor for the Internet of Things, working seamlessly with RedBear Duo.
Particle – You can use all Particle online tools and cloud messaging service for RedBear Duo for development and prototyping.
Particle offers a suite of hardware and software tools to help you prototype, scale, and manage your Internet of Things products. Help make Duo cloud ready right out of the box.
Seeed – Integration partner of our RedBear RBLink Board and their Grove System to keep prototyping quick and solder-less. Seeed will also manufacture all our Duo and RBLink boards.
Seeed is a hardware innovation platform for makers to grow inspirations into differentiating products. Seeed helps makers to productize their ideas/prototypes using their in-house engineering, supply chain management and agile manufacture forces.
