they provide an easy-to-use Bluetooth low energy master/slave network processor module, compliant with Bluetooth v4.2. The BlueNRG-M0 module supports multiple roles simultaneously and can act at the same time as Bluetooth low energy sensor and hub device. The entire Bluetooth low energy stack and protocols are embedded into BlueNRG-M0 module, the external host application processor, where the application resides, can be connected to the BlueNRG-M0 module through a standard SPI interface.
Anglia’s engineering team are also on hand to support designers with their extensive experience of wireless designs and can offer advice and support at component and system level. This expertise is available to assist customers with all aspects of their product design, providing hands on support and access to additional comprehensive STMicroelectronics resources including technical application notes and reference designs.
11.5mm with a low-profile height of just 2.5mm max. Bluetooth Radio, embedded antenna and high frequency oscillators are integrated into the modules to offer a certified solution that optimizes the time-to-market of the final applications. Both modules can be powered directly with a pair of AAA batteries or any power source from 1.7 to 3.6 V, and in the case of the BlueNRG-M0 directly from a standard 3 V coin cell battery.

The BlueNRG-M2 modules are a Bluetooth Low Energy system-on-chip application processor certified module, compliant with Bluetooth specifications v5.2 and BQE qualified. The BlueNRG-M2 module supports multiple roles simultaneously and can act at the same time as Bluetooth master and slave device. The modules embed the entire Bluetooth low energy stack and protocols and do not require an external processor to host the application reducing the demand on the host system processor. The BlueNRG-M2 is based on the BlueNRG-2 system-on-chip featuring a high performance, ultra-low power Cortex-M0 32- bit based core with programmable embedded 256 kB Flash and 24 kB embedded RAM with data retention. The module can deliver up to +8 dBm output power (Tx), receive (Rx) sensitivity down to -88 dBm and up to 96 dB link budget with excellent link reliability. The BlueNRG-M0 and BlueNRG-M2 modules provide a complete RF platform in a tiny form factor measuring just 13.5 x

To assist designers, STMicroelectronics have developed a comprehensive suite of hardware evaluation kits, software development kits (SDK) and PC tool ecosystem. These easy-to-use tools allow designers to evaluate the full capabilities of the BlueNRG portfolio of Bluetooth Low Energy SoC devices and modules. An example of this is the BlueNRG Navigator, which is an “out-of-the-box” solution that has a Graphic User Interface that provides a simple and user-friendly interface to browse, flash, and run application examples included in the SDK package. To further ease developers and enable fast adoption the whole product family is supported by leading edge 3rd parties Integrated Development Environment as well as STMicroelectronics free-of-charge and multi-platform Wireless Software Environment (WiSE). Also, STMicroelectronics is offering a BT SIG certified Bluetooth Mesh protocol stack capable to extend BLE adoption to
Summary
Whilst wireless connectivity can be a complex field, the BlueNRG Bluetooth Low Energy solutions from STMicroelectronics make Bluetooth integration into the end application a breeze whether you opt to use the SoC or certified module based products. Furthermore, the BlueNRG
applications requiring unlimited networking of multiple wireless nodes, such as appliances or sensors for the smart-home as well as lighting solutions for smart-building or industrial applications. There are also easy to use BlueNRG applications available on both Google Play and the Apple store which can be used with the various evaluation tools. Furthermore, there are PC utilities for features such as the radio initialization wizard, power consumption control/monitoring along with a flasher and ST-Link utility. The tools provide a set of hardware and
software resources for a wide range of application scenarios such as sensor data (accelerometer, pressure and temperature sensors), remote control (buttons and LEDs) and debug message management via USB virtual COM. The boards can be powered by USB only, battery only and external power supply plus USB for application development and testing flexibility.
Anglia offers support for customer designs with free evaluation kits, demonstration boards and samples of STMicroelectronics products via the EZYsample service which is available to all registered Anglia Live account customers.

portfolio is backed up with comprehensive hardware and software support tools that enable designers to get up and running in no time, and more importantly help accelerate the critical time-to-market.
And to re-iterate their commitment to supporting industrial designs, the BlueNRG portfolio is part of STMicroelectronics product longevity program which guarantees they will remain in mass production for 10 years from the product introduction date. This gives industrial product designers the confidence to integrate them into their applications knowing the parts will not be discontinued in a short space of time. Visit
