RFduino - Simblee Starter Kit

This is the Simblee Starter Kit, a great trio of products in one box to help you get you started with and teach you the basics of Simblee. Inside this kit you will find three boards, the Simblee DIP mainboard, the USB programming shield, and the RGB LED/Button shield. When attached, the Simblee mainboard and the USB programming shield will be able to connect to the USB port on your computer and get your code through the Arduino IDE onto the RFduino DIP board. Add in the RGB LED/Button shield to give you a few simple inputs and outputs.

The Simblee is a Bluetooth 4.0 Low Energy BLE RF Module with Built-In ARM Cortex-M0 for rapid development and prototyping projects. The Simble operates at 3.3V and only uses 10mA in RX mode (<3uA ULP), it also transmits on a 2.4 GHz band, and offers 128KB of flash memory with 24KB of RAM. Via a Bluetooth connection with your smartphone you can control or read data from your Simblee board in a custom interface. Meanwhile, on-board the RFduino USB Shield is a 3.3V regulator which can be used to supply power to the Simblee DIP module as well as other shields and possibly the rest of your circuit.

With this kit you won't need to worry about buying the USB shield separately, it's all in one box and ready to be used right away!

    Has the Simblee Module been discontinued? I'm working on a project (hopefully production) and sure could use these!

Fun but limited

This is a fun product to play with but it has its limitations. Its a good idea to read the documentation before investing. The iPhone UI support is limited to a handful of widgets and text boxes, plus undocumented bitmap support (the Thermometer and ColorWheel demos were created using the Xcode development environment). There is no mechanism to create custom objects nor general drawing functions like line, poly, circle or arc. Simblee is based on the Arm Cortex, not AVR, so existing Arduino libraries may not work. The supplied Servo app, for example, fails to compile due to Simblee's incompatibility with the Arduino servo library. Notably there is no access to the internal counter/timers for real-time applications, although external interrupts are supported. Hopefully we'll see some updates in the future to correct these limitations.

Up and running in no time

The helpful instructional video along with the extensive library programs made implementation of a wireless data logger quick and easy for this beginning C++ programmer. The Simblee is an excellent low power alternative to the higher power HopeRF modules when long range is not a requirement.
