Bluetooth Protocol Stack
The Bluetooth® Special Interest Group (SIG) [1] and [2] defines the protocol stack for Bluetooth low energy (LE) and Bluetooth basic rate/enhanced data rate (BR/EDR) technology. The fundamental objectives of these specifications is to develop interactive services and applications over interoperable radio components and data communication protocols.

Navigate inside tunnels with Bluetooth Beacons
Satellite navigation has revolutionized the way we get around. It’s cheap, fast and easy to use. But there’s one fatal flaw in the system: It simply can’t work underground.
GPS requires line of sight to satellites orbiting the planet. The great advantage of this is that it works seamlessly all over the world, without needing to be connected to a cellular or Wi-Fi network. This works well in open areas but in built-up areas with tall buildings, or in underground tunnels, the system can fall apart.

How Combining UWB and Bluetooth Low Energy Enables Innovation
A growing number of everyday digital devices, including things like smartphones, door locks, and even the latest cars, now use a wireless feature called spatial awareness. A spatially aware digital device can understand where it is in relation to other devices, and then respond to changes in the positioning of those devices. Spatial awareness makes it easier for us, the users of digital devices, to move through our days.

STMicroelectronics Bluetooth low energy expansion board based on the BlueNRG-M0 module for STM32 Nucleo X-NUCLEO-IDB05A2
The X-NUCLEO-IDB05A2 Bluetooth low energy expansion board is based on the BlueNRG-M0 BLE network processor module.
The BlueNRG-M0 is Bluetooth v4.2 compliant, FCC and IC certified (FCC ID: S9NBNRGM0AL; IC: 8976C-BNRGM0AL). It supports simultaneous master/slave roles and can behave as a Bluetooth low energy sensor and hub device at the same time.
The BlueNRG-M0 provides a complete RF platform in a tiny form factor, with integrated radio, antenna, high frequency and LPO oscillators.
The X-NUCLEO-IDB05A2 is compatible with the ST morpho (not mounted) and Arduino UNO R3 connector layout.
The X-NUCLEO-IDB05A2 interfaces with the STM32 microcontroller via the SPI pin and allows changing the default SPI clock, SPI chip select and SPI IRQ by replacing a resistor on the expansion board.
