The Bluetooth Special Interest Group (SIG) has published the specs for the next generation of Bluetooth devices. Bluetooth 4.2 has a few improvements that will be of particular interest to developers of IoT devices. The biggest change is support for an Internet Protocol Support Profile (IPSP) which enables IPv6 for Bluetooth. This means that wearable or IoT devices (based on Bluetooth Low Energy) will not need to be paired with a smartphone or tablet to gain access to the cloud, they will have access to the internet via a Bluetooth/WiFi enabled router.

Find out the WunderBar – the OpenSensor Cloud Platform enabling to easily develop applications for the physical world.
The WunderBar IoT (Internet of Things) Starter Kit from company relayr mimics the appearance of a chocolate bar with a WiFi enabled master module, plus six detachable smart sensor mini-modules.
The WunderBar Internet of Things WiFi & Bluetooth Sensor Starter Kit is a quick start development tool for software application developers unfamiliar with complex wireless hardware designing, and a complete open-source wireless hardware reference design. WunderBar provides to hardware design engineers an out-of-the-box development tool that helps users get started quickly building, inventing, developing, and experimenting with Internet of Things senor based designs using WiFi and BLE senor applications.
Made of seven modules, the WunderBar main module is fitted with an ARM Cortex ‘M’ micro -processor, which connects to the internet through the WiFi unit. Bluetooth Low energy is used to communicate with the other modules. All of the activity that happens around the WunderBar is sent to the WunderBar platform, where you can easily access and work with the signals.
Break, place and program
It works right out of the box. It is energy efficient, fast, secure and designed for developers, makers and manufacturers.
WunderBar has six powerful smart modules, each equipped with its own Bluetooth Low Energy (Beacon) processors and battery that can power the units for up to a year. Light / Color / Proximity, Gyroscope / Accelerometer, Thermometer / Humidity, IR Transmitter (remote control), A connector to the easy Grove System of Sensors and Actuators that are all Arduino compatible and a Noise/Sound sensor. The Starter Kit has available for download various software development kits (SDKs) for iOS, Android and Node.js. including test Apps which can be downloaded from relayr.io. Libraries for node.js, python and more will be supported soon.
WunderBar is the easiest way to create innovative and useful apps to connect smart devices without needing to learn about hardware. App developers can quickly access data from the physical world with WunderBar’s easy-to-use SDKs for iOS, Android and Node.js or with our simple REST API.
Because the WunderBar is still a dev kit, with a little bit of knowledge, and the exposed GPIO pads, you can make almost anything you want smarter. More info at: www.relayr.io/wunderbar The WunderBar will soon be our standard stock item.

What´s more, M66 is currently the smallest quad band GSM/GPRS moduloe in the world … AT the same time it withstands strong frosts, so it´s ready for a wide spectrum of applications.
New extraordinary attractive communication module Quectel M66 asks its place maybe even in your application.
Does it deserve it? Most probably yes. Besides two basic facts mentioned in the name and perex of this article, it offers a lot of “smallnesses” making the life of a developer easier, for example:
- Quectel OpenCPU functionality
- power consumption only 1.3 mA (DRX=9)
- easily applicable LCC package suitable for small and also big production series
- powerful internet protocols embedded
- based on the newest 2G chipset ensuring a long lifetime (availability) of the module
- GPRS multi slot class 12
- 3x UART/ 1x RTC
- DTMF, QuecLocator, QuecFOTA for a simple software update, eCall
What to add? For a real decision and usage in your device we bring you the M66 presentation and mainly a complete documentation M66 (30 MB). In this package can be found a detailed description, various application notes, description of AT commands as well as SW tools.
MM66 offers a stable platform to build a quality product, moreover for an attractive price. As usually, even M66 is also available on a so called adaptor board – M66TE-A nabling usage through a connector – without soldering and also usage in a universal development kit M10EVBKIT.
Within a frame of novelties in Quectel communication modules, there´s also available the second version of the M95 – module – M95 R2.0, marked as M95FA which is fully compatible with a previous version of M95 but it also has another features like digital audio, DSSS a SSL.
Another novelty is the GPS/Glonass module L76 offering an advanced functionality, excellent sensitivity and various services (AlwaysLocate, advanced AGPS, LOCUS, …).
Comprehensive comparison of current Quectel modules can be found in the Quectel v3.4 brochure.

LED matrices are a popular mean of displaying text, graphics, and animated information at gas stations, convenient stores, and many other public places. Raj’s new project is about making a Bluetooth-enabled 8×64 LED matrix display, where you can send the text messages through a smartphone over a Bluetooth connection. He used Arduino as the main controller and an HC-06 Bluetooth adapter to receive data from the smartphone. He has shared all of his design files and Arduino firmware on his blog.

What could you make with a key fob containing a Bluetooth (BCM20737S) Smart chip, gyroscope, accelerometer, compass, barometer and humidity/temperature sensors? Broadcom are hoping their WICED (pronounced wicked) Sense kit will make an ideal development platform for engineers and developers working on the next generation of IoT applications. Together with the hardware Broadcom have an integrated Software Development Kit (SDK) using the WICED Smart SDK v2.1 and a downloadable WICED Sense app from the Apple App store or from Google Play for Android devices to allow interaction with the fob via a smartphone or tablet etc.

Brett’s new masterclock is Arduino-controlled and keeps very accurate time by periodically synchronizing with the DCF77 “Atomic” Clock in Mainflingen near Frankfurt, Germany. The DCF77 library for Arduino is used to decode the time signal broadcasted from the atomic clock. The time is displayed as hours, minutes, and seconds on six 1″ seven segment LEDs. A 4×20 I2C LCD display is also used in the project to display additional info such as display brightness, sync information, signal quality, auto tune’d frequency, auto tuned quartz accuracy, etc. Both the displays are auto-dimmed based on the surrounding light intensity using an LDR sensor and pulse width modulation technique. His clock also includes a bluetooth link for updating the Arduino firmware from a PC without an USB cable.

Microchip Technology Inc has introduced a PIC32 Bluetooth starter kit. The kit includes a board with a PIC32 microcontroller, HCI-based Bluetooth radio, Cree high-output multi-color LED, 3 standard single-color LEDs, an analog 3-axis accelerometer, analog temperature sensor and 5 push buttons for user-defined inputs. In addition the PICkit™ On Board (PKOB) eliminates the need for an external debugger/programmer and supports USB connectivity and GPIOs for rapid development of Bluetooth Serial Port Profile (SPP), USB and general-purpose applications. To support Bluetooth audio the starter kit also includes an interface for a plug-in audio CODEC daughter card set for release at a later stage.
