All-in-one module to install Bluetooth for IoT connectivity

August 18, 2015 // By Graham Prophet
Silicon Labs’ Blue Gecko BGM111 module comes with a pre-installed BLE (Bluetooth Low Energy) stack, and its scripting language provides a plug-and-play solution with an SoC migration path.

This fully integrated, pre-certified Bluetooth Smart module gives developers a fast path to low-power wireless connectivity for the IoT. The new BGM111 module is the first in a family of advanced Blue Gecko modules from Silicon Labs delivering integration, flexibility, energy efficiency and toolchain support with migration path to Blue Gecko system-on-chip (SoC) solutions.

Based on Silicon Labs’ Blue Gecko wireless SoCs, the BGM111 modules are presented as reducing development costs and regulatory compliance effort by providing a plug-and-play Bluetooth Smart design pre-certified for use in key markets including North America, Europe and Asia-Pacific. The BGM111 modules are pre-loaded with the Bluegiga Bluetooth 4.1-compliant software stack and profiles and are field-upgradable using device firmware upgrades to Bluetooth 4.2 and beyond.

The BGM111 module simplifies dealing with RF design, Bluetooth Smart protocol and embedded programming. Developers can begin Bluetooth development with BGM111 modules and then transition to Blue Gecko SoCs when needed, with minimal system redesign and full software reuse.

The BGM111 module is supported by Silicon Labs’ wireless SDK using either a host or fully standalone operation through the Bluegiga BGScript scripting language. Using a BASIC-like syntax, BGScript enables developers to create Bluetooth applications quickly without using external MCUs to run the application logic. All application code can be executed on the BGM111 module, eliminating the need for an external MCU. Bluetooth Smart application profiles and examples are also available to streamline development.

The BGM111 modules incorporate all features of Blue Gecko SoCs and come with 256 kB flash and 32 kB RAM, providing memory for onboard applications. The SoC’s built-in hardware cryptographic accelerator supports evolving security requirements. Flexible hardware interfaces enable connection to a variety of peripherals and sensors. An integrated, high-efficiency antenna makes RF design and operation consistent and straightforward for developers of all skill levels.

The BGM111 module’s ultra-low power operation enables Bluetooth Smart systems to be powered from a standard 3V coin cell battery or two
