TexasSimplelink_300

by elektor.com:

TEXAS Instruments has announced the new SimpleLink ultra-low power wireless MCU platform. The platform has been designed to use so little energy it can be powered from harvested energy or will run for years on a coin cell. For versatility the platform supports multiple wireless connectivity standards using a single-chip and identical RF design. The SimpleLink ultra-low power platform supports Bluetooth low energy, ZigBee, 6LoWPAN, Sub-1 GHz, ZigBee RF4CE and proprietary modes up to 5 Mbps.

The first members of the SimpleLink devices to be introduced are the CC2640 which supports Bluetooth Smart and the CC2630 for 6LoWPAN and ZigBee. The CC2650 wireless MCU supports multiple 2.4 GHz technologies including Bluetooth Smart, 6LoWPAN, ZigBee and RF4CE. The support for such a wide range of radio standards helps future-proof designs and gives the ability to configure a chosen technology at the time of installation in the field. Planned for introduction later in 2015 are the CC1310 for Sub-1 GHz operation and the CC2620 for ZigBee RF4CE.

BlueGecko

by elektor.com:

At the Embedded World conference held in Nuremberg, Germany this week Silicon Labs unveiled its Blue Gecko platform aimed squarely at Internet of Things applications. Silicon Labs have combined both their EFM32 Gecko MCU technology together with a 2.4GHz Bluetooth Low Energy transceiver (including a power amp and balun giving at least +10 dBm output power) on one die.

The 32-bit MCU inside the wireless SoC runs Bluetooth protocol stacks and scripting language developed by Bluegiga. Blue Gecko SoCs are based on ARM Cortex-M3 and M4 cores with 128 to 256 Kbyte flash and 16 to 32 Kbyte RAM. Silicon Labs are offering the complete Bluegiga Bluetooth Smart software stack for Blue Gecko modules and wireless SoCs. The stack implements the Bluetooth Smart protocol layers including the Attribute Protocol (ATT), Generic Attribute Profile (GATT), Generic Access Protocol (GAP) and security manager together with connection management.

What a CAM Drive can or can not do:

A CAMdrive node must be selected according to the motor.
That is:
Stepper motors need a Stepper Controller of CAMDrive.
Normal DC motors need a CAMdrive-BrushedDCMotor controller.

To connect with Bluetooth, only one node needs the Bluetooth module. The remaining nodes are wired via the bus.

There is only one power supply required! No matter which node is connected, it supplies the remaining nodes and motors on the bus

It does not matter on which node the camera is connected, it all work “Camera” jacks simultaneously.

The bus connection is established via a standard network cable (patch cord).

Bob Alexander of Galactic Studios made this bluetooth serial monitor for embedded microcontroller projects, the Blueprintf:

One way of debugging microcontroller-based projects is to send messages out the UART serial port. Then, a UART-to-USB interface can feed the messages into your PC for display. But I wanted a small, portable device for viewing serial data without a PC, and I wanted it to use my cell phone or tablet for its display.
There are a few advantages to this. First, I don’t always have my PC nearby; maybe the project worked fine on my workbench, but doesn’t work “in the field” where I don’t have a PC handy. Second, the UART-to-USB interface sometimes hangs, especially if there are glitches from the system under test (SUT). Finally, sometimes I just don’t want to string the wires from the embedded system to my PC

Control your Bluetooth enabled devices with this open-source button that is only slightly larger than a micro SD card.

Tog can remotely control Bluetooth enabled devices such as smart phones, laptops, lights, locks and much more. When you press Tog it will wake up and communicate with your phone to execute pre-assigned actions. Tog ships with the ability to activate Siri/Google or take a picture on your smart phone with no apps required. Additionally, you may configure it to control or mute your music. The Tog design is open source so it can be modified to do whatever fits you.

So you want to two HC-05 modules to automatically connect together, as soon as they’re powered up and with zero code? Well this is your lucky day since this can be done using the AT+BIND command.
Let’s do this thing!
For this, you will need:
1 Arduino (I’m using UNO)
2 HC-05 modules
1 breadboard
Wires
Arduino IDE (I’m using version 1.0.5-r2)

Bluetooth4.2

by elektor.com:

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.
