物联网发展到如今，无线技术纷繁复杂，往往会出现在同一区域的不同设备上，这些无线通信设备之间会出现相互干扰的现象。然而，蓝牙5标准可以减少和其他无线通信技术之间存在的干扰，帮助设备在复杂的物联网环境中与其他无线设备并存。
蓝牙5是由蓝牙技术联盟在2016年提出的蓝牙技术标准，蓝牙5在蓝牙4.2核心规范上大幅提升效能，包括「2倍的传输速度」「4倍的传输距离」「8倍的广播数据传输量」等新优势，强化了在物联网方面的新特性,重点提高物联网的功能。

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.
