Getting Started - RedBear DuoCongratulations on being the owner of a brand new RedBear Duo! Now, you can open the box and follow this guide to play with theDuo.This getting started guide will show you how to use the RedBear Duo IoT development board quickily. There are two sections:Out of the box testChecking firmware versionChecking device IDUpdating firmwareAssocaiting to an Access Point (AP) or Internet routerDevelop an application using WebIDE or Arduino IDE.Prerequisites for SetupYou need to prepare the following hardware items:PC with Windows, Linux (e.g. Ubuntu) or Mac with OSXTested on: Windows 10, OSX 10.11Access Point (e.g. an Internet router at your home).For the Duo to have Internet connectionMicro USB cableNote: some cables only for power, you need a data+power cable for the Duo.RBLink (optional, easier with its drag & drop feature)Software items:dfu-utilLatest Duo Firmwarehttps://github.com/redbear/Duo/raw/master/firmware/For Windows, you also need the following software tools:PuTTYor you can use other serial port tool (e.g. HyperTerminal)DriverZadigOut of the Box Test1. Power-Up the DuoConnect the Duo to your PC via the USB port with a micro USB cable.The RGB LED will show Blue in color and keep flashing (i.e. Listening Mode).
2. Install Driver (Only required for Windows)Follow this driver installation guide for details.3. Install PuTTY (Only required for Windows)Note: you can also use other Serial port communication software (e.g. HyperTerminal).Download and unzip PuTTY.4. Check firmware version and device IDFor WindowsStart PuTTY, change the Serial port to your one and press the 'Open' button.Press 'v' to the terminal screen, you will see the firmware version.Press 'i', you will see the Device ID of the Duo.
For OSX or LinuxStart the Terminal and use 'screen' command.For example on OSX, startNote: on Linux (e.g. Ubuntu), you may need to install screen by '$ sudo apt-get install screen'.Type: For OSX: $ screen /dev/tty.usbmodemXXXXX where XXXXX is your Duo device serial port. For Linux: $ screen /dev/tty.ACMX where ACMX is your Duo device serial port.Press 'v' to the terminal screen, you will see the firmware version.Press 'i', you will see the Device ID of the Duo.It will show something like the following lines: system firmware version: 0.1.1 Your device id is 200027FFFc473530FFF23637Note: after using the 'screen' command, type 'reset' to clear the screen.5. Updating FirmwareYou can use bootloader DFU or the RBLink to update the Duo firmware.DFU Mode:Follow this DFU to install the 'dfu-util' tool.Download the zipped Duo firmware (latest version) for DFU with '_dfu' ending in the filename and unzip it to a folder.https://github.com/redbear/Duo/raw/master/firmware/e.g. v0.2.1, browse the firmware folder or click here to download directly.Start the Command Prompt (Windows) or Terminal (OSX)If you are not in the DFU Mode, press and hold the 'SETUP' button on the Duo and then press the 'RESET' button, when theRGB LED shows yellow and flashing, release the 'SETUP' button, the Duo will enter the DFU Mode.From the command line box:
To update System-Part1, type: $ dfu-util -d 2b04:d058 -a 0 -s 0x08020000 -D duo-system-part1.bin To update System-Part2, type: $ dfu-util -d 2b04:d058 -a 0 -s 0x08040000 -D duo-system-part2.bin To update User-Part, type: $ dfu-util -d 2b04:d058 -a 0 -s 0x080C0000 -D duo-user-part.bin To update factory reset image, type: $ dfu-util -d 2b04:d058 -a 2 -s 0x140000 -D duo-fac-tinker.binSample output: dfu-util 0.8 Copyright 2005-2009 Weston Schmidt, Harald Welte and OpenMoko Inc.

File downloaded successfully After updating the firmware, press the onboard 'RESET' button to run the new firmware.RBLink:Stack the Duo on top of the RBLink through the connectors.
Connect the RBLink USB port to your PC using a micro USB cable.Note: not the Duo USB port this timeDownload the zipped Duo firmware (latest version) for RBLink with '_rblink' ending in the filename and unzip it to a folder.https://github.com/redbear/Duo/raw/master/firmware/e.g. v0.2.1, browse the firmware folder or click here to download directly.The firmware inside the Duo locks the flash for protection, so you need to unlock it first. In your computer, there is a diskdrive call 'RBLink', drag & drop the 'duo_unlock.bin' to the RBLink drive.After that, the RGB will show in green and flashing very fast. Disconnect the USB from your PC and reconnect it again,the RBLink drive will appear again.Now, drag & drop the new firmware (duo_fw_rblink.bin) to the RBLink drive.
After that, the Duo will start the new firmware and the RGB will show in blue flashing (i.e. Listening mode for WiFiprovisioning).Note: everytime you use RBLink to updat the firmware, the WiFi settings stored in the DCT will be cleared. So, you needto do the WiFi setup procedure again.6. Check Firmware Version AgainRepeat the step 4 again to check the new firmware version. Sample screen output: system firmware version: 0.2.1 Your device id is 200027FFFc473530FFF23637For more details about the Duo firmware management, refer to the Firmware folder.Now, please write down the device ID, it is required to do registration on Particle website in order to use their Cloud service andonline Web IDE for firmware development.7. Setup WiFiAssume you are still in the 'Listening Mode' (i.e. RGB LED in flashing blue)Connect to the Duo using 'PuTTY' tool or 'screen' command.Type 'w', it will ask you to enter the SSID, Security type and password to associate to your AP (or your Internet router).Sample input and output:
system firmware version: 0.2.1 Your device id is 200027000c47353033323637 SSID: AP-01 Security 0=unsecured, 1=WEP, 2=WPA, 3=WPA2: 3 Password: YOUR_PIN_ONLY_YOU_KNOW Thanks! Wait while I save those credentials... Awesome. Now we'll connect! If you see a pulsing cyan light, your device has connected to the Cloud and is ready to go! If your LED flashes red or you encounter any other problems, visit https://www.particle.io/support to debug. Particle <3 you!If everything is ready, it will try to connect your AP and the RGB will flash in Green and then change to Cyan. RGB Color Status: Flashing Green : Try to connect the AP you entered. Breathing Green : Connected to the AP. Flashing Cyan : Trying to connect to the Particle Cloud. Breathing Cyan : Connected to the Cloud.If you have made the input incorrectly, you can press the 'SETUP' button for 3 seconds (you will see the RGB in blue color) atanytime to start the 'Listening Mode' again.8. TestingNow, you can test the board. The user part firmware is a Web Server and there is a mDNS service running.Reset your board and then use 'PuTTY' or 'screen' to connect it.The WebServer Firmware will wait your router for an IP address to be assigned via DHCP and it will show the following messageto the USB CDC (serial) port: Arduino sketch started. Note: If your Duo hasn't stored a valid WiFi profile, it will enter the listening mode for provisioning first. Waiting for an IP address... Duo's web server IP Address: 192.168.1.11 Make sure your smart device acting as web client is connecting to the same AP as Duo. Then open the web browser on your smart device and enter the Duo's web server IP address. setService mdns.begin mdns/setup successTry to use a Web Browser (e.g. Safari or Chrome) to browse the Web Server. If your browser support mDNS, you can just type'duo.local' as the URL. Otherwisw, type 'http://192.168.1.11' as an example.Note: this is a sample IP address, it should be your own IP address displayed in the 'PuTTY' or 'screen'.
Press the 'HIGH' or 'LOW' button to see any effect on your Duo's blue LED.WebIDEMake sure you are connected to the Cloud (RGB in breathing cyan).From you PC, start a Web Browser, navigate to Particle build website.Create a Particle account if you do not have one.Bottom left corner, there is an icon - Devices, click itAnd then press 'ADD NEW DEVICE'.Enter your device ID to the box to claim your Duo.Give a name to your Duo and then press the 'save' button.
Your Duo will be listed in 'Other Devices', refresh the whole page, you will see it correctly. The cyan dot means it is online.Now, try to load the Blink example and flash it to your Duo over the Cloud.Great job!
