Bluetooth smart module provides long-range connectivity

With TX power up to 8dBm, RX sensitivity down to -93dBm, and up to 200 meters range, the BGM111 has excellent RF performance and can provide long-range, robust Bluetooth Smart connectivity.

The module integrates Bluetooth radio, an antenna, Bluetooth Smart software stack, and GATT-based profiles, and includes the Profile Toolkit, which allows designers to create additional GATT-based services. The module also includes a 32-bit ARM Cortex-M4 processor and can host end-user applications, which eliminates the need for an external microcontroller in devices with size, price or power constraints.

It has flexible hardware interfaces — including UART, SPI, and I²C — to connect to different peripherals or sensors. The module offers up to 25 GPIO with interrupts, four 12-bit analog-to-digital converters (ADCs), one 12-bit digital-to-analog converter (DAC), an internal temperature sensor, autonomous hardware crypto accelerator, and an integrated DC-DC buck converter.

The module has a wide input voltage range, from 1.8V to 3.8V, enabling engineers to power wireless system designs from a single 3V coin cell battery or two AAA batteries.

Mouser Electronics is also shipping the Silicon Labs SLWSTK6101A Bluetooth Smart Module Wireless Starter Kit. This starter kit features an on-board J-Link debugger, a virtual COM port interface, an LCD display and a humidity/temperature sensor and test points to access all the pins of the Blue Gecko Bluetooth Smart Modules.

The WSTK6101A Wireless Starter Kit is supplied with an expansion board (BRD8006A Add-on Board) that can be connected to the WSTK mainboard expansion header. The expansion board contains additional peripherals such as an accelerometer, buttons, LEDs, joystick, and an I²C expansion slot.

The Bluetooth Smart Module targets low-power, wireless applications, such as sports and fitness tracking, health and medical devices, Internet of Things (IoT) connectivity, and home and factory automation.
