According to Cypress, the PSoC 4 BLE delivers “unprecedented ease-of-use and integration in a customizable solution for IoT applications, home automation, healthcare equipment, sports and fitness monitors, and other wearable smart devices.” The PRoC (programmable radio-on-chip) is “intended for wireless Human Interface Devices (HIDs), remote controls, and applications that require wireless connectivity.”
Cypress also announced BLE development kits and reference designs.
- CY8CKIT-042-BLE Development Kit: The kit includes a USB BLE dongle that “pairs with the CySmart master emulation tool, converting a designer’s Windows PC into a Bluetooth LE debug environment.”
- CY5672 PRoC BLE Remote Control Reference Design Kit: The remote control has a trackpad to detect two- and one-finger gestures and includes a built-in microphone.
- CY5682 PRoC BLE Touch Mouse Reference Design Kit: The touch mouse reference design includes buttons that map to common user interface shortcuts for Windows 8.
According to Cypress, the PSoC 4 BLE and PRoC BLE solutions are currently sampling in 68-ball CSP and 56-pin QFN packages. Production is expected in December 2014.

ASIX Electronics Corp. has launched five AXB series embedded Bluetooth modules, the AXB031/AXB033 for Internet of Things applications and the AXB051/AXB052/AXB081 for wireless audio applications. You can connect the AXB modules to any MCU with UART interface, or you can operate it as a standalone unit without an MCU.
The Bluetooth 4.0 AXB031 and AXB033 modules are well suited for wearable applications, such as medical sensors and activity monitors, as well as commercial/industrial automation and smart home applications.
According to the company’s release, ASIX offers “developers a full-featured Bluetooth Smart stacks and application development environment to make it easy to add Bluetooth Smart to embedded system. In addition, ASIX also provides a dual-mode Bluetooth 4.0 audio module, AXB081, and two Bluetooth 3.0 audio modules, AXB051/AXB052, for the fast-growing wireless audio applications, such as wireless stereo speakers, headphones, home theater, automotive hands-free, and MirrorLink car player applications.”
Texas Instruments recently introduced an innovative wireless haptic development kit. The DRV2605EVM-BT haptic Bluetooth kit comprises a 32-mm square PCB containing a DRV2605 haptic driver chip that controls an eccentric rotating mass motor (ERM) and a linear resonant actuator (LRA) to produce vibrations. The DRV2605 has an integrated library with more than 100 effects licensed from Immersion Corp.

You can use a circle of LEDs to display visual alerts. The board might be useful to speed up development times when designing and testing haptic effects in applications such as: watches, fitness trackers, wearables, portable medical equipment, touch screens, displays, and other devices requiring tactile feedback.
A SimpleLink Bluetooth low-energy CC2541 wireless microcontroller communicates with a free iOS app running on an iPhone or iPad. The app allows you to play predefined library waveforms, create new waveform sequences, and assign waveform sequences to in-app notifications. The app can also be used to quickly configure the DRV2605’s internal register settings: select between an ERM or LRA actuator, set the rated and overdrive voltages, configure and run autocalibration, send direct I2C commands, as well as set up the board to respond to a GPIO trigger.
The DRV2605EVM-BT haptic Bluetooth kit costs $99.

PICkit On Board (PKOB) eliminates the need for an external debugger/programmer, USB connectivity, and GPIOs for rapid development of Bluetooth Serial Port Profile (SPP), USB and general-purpose applications. The starter kit also features a plug-in interface for an audio CODEC daughter card. The kit’s PIC32MX270F256D microcontroller operates at 83 DMIPS with 256-KB flash memory and 64-KB RAM.
The PIC32 Bluetooth Starter Kit is supported by Microchip’s free MPLAB X IDE and MPLAB Harmony Integrated Software Framework. Additionally, the free Quick Start Package is available with an Android application development environment. It also includes a free SDK with the application source code and binary for Microchip’s Bluetooth SPP library. Both are optimized for the on-board PIC32 MCU and are available for free at www.microchip.com/get/1AVL.
The PIC32 Bluetooth Starter Kit costs $79.99.
Microchip Technology recently announced its first Bluetooth 4.1 Low Energy module, the RN4020, which carries both worldwide regulatory certifications and is Bluetooth Special Interest Group (SIG) certified. The integrated Bluetooth Low Energy (BTLE) stack and on-board support for the common SIG low-energy profiles speeds time to market while ensuring Bluetooth compatibility, eliminating expensive certification costs and reducing development risks. The module comes preloaded with the Microchip Low-energy Data Profile (MLDP), which enables designers to easily stream any type of data across the BTLE link.
The RN4020 is a stack-on-board module, so it can connect to any microcontroller with a UART interface, including hundreds of PIC MCUs, or it can operate standalone without an MCU for basic data collection and communication, such as a beacon or sensor. Standalone operation is facilitated by Microchip’s unique no-compile scripting, which allows module configuration via a simple ASCII command interface—no tools or compiling are required.
The RN4020 Bluetooth Low Energy Module is available for $6.78 each in 1,000-unit quantities.
