Red Bear IoT Development Kit

The kit has two boards, the Duo board and the RBLink board.

*** There is an issue with OSX 10.11, the RBLink will not work (with OpenOCD/libusb). As a workaround, please use MSD (drag & drop) method, OSX 10.10 or Windows at this moment.

Red Bear Duo

The Red Bear Duo contains a ST32F205 MCU and AP6212A WiFi+Bluetooth combo module. The MCU has 1MB Flash and 128KB RAM, running at 120MHz. The wireless combo module built with BCM43438 A1 chip that works at 2.4GHz in frequency.

WICED SDK

To use the board with WICED SDK 3.3.1:

1. Download Broadcom WICED-SDK-3.3.1 from:

   • http://community.broadcom.com/docs/DOC-2312

2. Unzip WICED-SDK-3.3.1 to your local file-system

3. Download and copy the files in this add-on package to the WICED-SDK-3.3.1 you just unzip and replace the original files

RedBear RBLink (Programmer)

The programmer is based on STLink:

1. For Windows, go to ST official website to download and install the STLink driver:

   • http://www.st.com/web/en/catalog/tools/PF260219

2. No driver is required for OSX and Linux

3. Connect your RBLink USB to your PC using a micro USB cable

4. Open the command line terminal and change the working directory to WICED-SDK-3.3.1>

5. Type in "make rbl.rgb-RB_Duo JTAG=RBLINK download run" and press the Enter on the keyboard to begin build the project that under the folder "WICED-SDK-3.3.1\apps\rbl\rgb". More details about make usage please refer to the Makefile which under "WICED-SDK-3.3.1"

• Remember to short the JTMS D7 and JTCK D6 jumpers (as the photo shows) before burning firmware to the board.

Compilation

To test WiFi, you can use this command, it is a AP scanner demo:

"make snip.scan-RB_DUO_ES2 JTAG=RBLINK download run"

To test Blutooth LE, you can use this command, it is a proximity reporter demo:

"make snip.bluetooth.ble_proximity_reporter-RB_Duo_ES0 JTAG=RBLINK download run"

• if your board with AP6212 module, please use -RB_Duo_ES0 in the command and for AP6212A, please use -RB_DUO_ES2

Drag-N-Drop Programming

RBLink supports drag and drop programming, so you can easily deploy your firmware.

Using this command to compile "make rbl.rgb-RB_Duo" in teminal, after that, it will create a file with ending "_MSD.bin", simply drag and drop it to the MSD drive via the RBLink.

Unload the Duo

Some other firmwares may lock some sessions of the Flash area, use the unlock firmware to unlock it first before uploading any WICED firmware.

Other Tools

The RBLink is compatible with the STLink Utility http://www.st.com/web/en/catalog/tools/PF258168
