The Wifi Arduino 85 is a small board with ESP8266 -01 module, Attiny85 micro controller and a relay. It Also has and additional header for connecting an external relay or to connect sensors like PIR, IR etc depending on your application. If you are a tinkerer you will also be able to connect a HC-05/06 Bluetooth module and convert this board to a Bluetooth Arduino 85 board.

Resolving the position of free roaming robots can be quite challenging. You can only expect to get accuracy of around 6 to 10 meters by using a standard low-cost GPS system and that can be further downgraded by poor signal strength inside buildings. Bluetooth and WiFi positioning can achieve 1 to 5 metres resolution but that’s often not enough. The Pozyx system has been developed to achieve a positional accuracy of 10 cm and works indoors or outdoors.
Four ‘Anchor’ transceiver units attach to walls or fences surrounding the space in which the Pozyx Shield operates. Communication between the shield and the four anchors allows the shield to determine its position and orientation within its operational area.

Ham radio is a popular hobby and service in which a licensed amateur radio operator explores communications equipment. Typical ham radios do not have bluetooth support, which may be hassle for some. None of the transceiver manufacturers are providing a wireless interface. However, with this ham radio bluetooth interface, communicating and listening to other entity would be easier. The device uses Bluetooth module and a circular connector. The TE’s CeeLok FAS-T connector is one of the most rugged, small, 10 GB Ethernet, field terminable I/O connector. It has been designed to perform in some of the most extreme environments in the industry, while providing substantial size and weight savings via its small shell size 8-form factor.
The design is simple that anyone can construct it without having a hard time. The device uses a Bluetooth module, a regulator, connector and few passive components. It automatically connects to the PC or any bluetooth supported device when the application is started. Wireless headset would be very useful for ham radio operators so they can freely do whatever they need to do without being stagnant. In addition, a single blue LED indicates power and pairing.
Licensed amateur radio operators communicate with each other in nearby places, across the country, around the world or even with astronauts in outer space. Hams use a variety of frequencies for communications and may operate from just above the AM broadcast band to the microwave region, in the gigahertz range. This device may be useful for other applications such as aerospace, in flight entertainment and connectivity, defense and marine environments.

This project starts a few weeks ago. My six years old daughter usually sleeps with a light on in her bedroom. Talking with her, we decide to hack her LAMPAN Ikea lamp to make some improvements, including a manual RGB controller to set the light colour, a timeout to turn off the light after 30 minutes without changes and a bluetooth connection to control the lamp with a smartphone or tablet. So, if you continue reading the post, you’ll see what we develop!

Following on from the release of their PSoC 4 BLE chip at the Electronica Exhibition last year, Cypress Semiconductor Corp are extending their play in the Bluetooth market with the introduction of their new EZ-BLE module. The module contains the PSoC 4 BLE chip together with two crystals, an on-board chip antenna, RF shielding and passive components, all in a compact 10 mm x 10 mm x 1.8 mm form factor so that designers using the module can apply to add the Bluetooth logo on their products by referring to Cypress’s Qualification Design Identification (QDID) 67366, a unique serial number assigned by the Bluetooth SIG. The module is compliant with wireless regulatory standards in the U.S., Canada, Japan, Korea and Europe and offers a significant saving for designers in development, testing and certification costs.

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.

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.
