TMicroelectronics – BlueNRG-MS Bluetooth 4.1 Network IC
Among a plethora of Bluetooth® 4.1 compliant devices, the BlueNRG-MS IC, exhibiting an unparalleled low current consumption, is ideal for applications that need to operate for months or even years while being powered from a small coin cell battery. Running a complete, upgradable BLE stack on an embedded Cortex®-M0 core, it is also connected through a proprietary SPI-based interface to a host MCU running the application. Supporting both master and slave roles, the BlueNRG-MS can operate as a central (managing up to 7 peripherals) or peripheral device without any change in the firmware.
