Laird Technologies launches low-energy Bluetooth smart modules for medical and other devices

Medical devices that send small amounts of data wirelessly will be able to run for months or even years on a coin cell battery when they use a new Bluetooth Smart module launched by global Laird Technologies. The BL600 modules, each the size of a dime, are suitable for a broad range of devices including in-home medical devices, battery-powered sensors, data collection devices, and health and fitness equipment and applications.

The world market for Bluetooth Smart, which uses Bluetooth Low Energy (BLE) technology, is poised for explosive growth and sales of Bluetooth Smart devices could grow from 5.4 million devices in 2012 to nearly 160 million units in 2016, according to industry analyst IMS Research.

The BL600 modules include Laird’s smartBASIC, an event-driven programming language that simplifies BLE module integration. Even those with little software or Bluetooth expertise can develop fully functional applications in just days.

Those applications, along with a complete BLE stack, reside on the module itself and do not require an external microcontroller or memory. Every BL600 Series (BL600) module simplifies the process of adding single-mode Bluetooth Smart to any small, portable, power-conscious device.

Based on the Nordic Semiconductor nRF51822 system-on-a-chip (SoC), the BL600 modules provide low power consumption with increased wireless range. The modules support a variety of ultra-low power saving modes to achieve as little as 1000 nanoamperes (1000 nA, or 1uA) of power consumption in deep sleep mode and 10.5 mA when transmitting data at 0 dBm.

Each BL600 module version – with an integrated antenna, an IPEX MHF4 antenna connector, or trade pads for an external antenna – has a compact footprint of 19 mm x 12.5 mm, making it suitable for small portable devices. A BL600 module can connect to a wide array of external sensors via its I2C, SPI, UART, ADC, and GPIO interfaces.

In addition to carrying FCC modular, IC, MIC and CE approvals, BL600 modules are fully qualified as Bluetooth End Products, enabling designers to integrate the modules in devices without the time and expense of recertification.
