Introduction

The official link of STM where can be found in both the BT Classic (3.x) that the new BT 4.x or BTLE (components and modules) is this.

BT technology

Up to now there are different release of BT, for example there is the Classic BT v2.1, v3.0 and there is the new BTLE v.4.x
For see the differences from the different release of BT see here and here.
Here I want to highlight the differences inside the BTLE 4.x that are: Smart Ready and Smart (see below).

bttopology

Very important is that with the BTLE is not necessary use the Apple Crypto Chip for release the APP for iOS.

          • STEVAL-WESU1 – Wearable sensor unit reference design for fast time to market

    •  Modules

      • SPBTLE-RF – Based on Embedded BlueNRG component.
        The SPBTLE-RF is an easy to use Bluetooth® low energy (BLE) master/slave network processor module, compliant with Bluetooth v4.1.
        The SPBTLE-RF module supports multiple roles simultaneously, and can act at the same time as BLE sensor and hub device.

        • The evaboard is: X-CORE-IDB05A1 Bluetooth Low Energy expansion board based on SPBTLE-RF module.
          There are a lot of examples ready to use on STM32.
      • SPBTLE-RF0  – Based on Embedded BlueNRG-MS component
        The SPBTLE-RF0 is an easy to use Bluetooth® Low Energy (BLE) network processor module, compliant with Bluetooth v4.1.
        The SPBTLE-RF0 module supports multiple roles simultaneously, and can act at the same time as BLE master and slave device.

        • Coming soon
      • SPBTLE-1S –  SPBTLE-1 low power module for Bluetooth v.4.2 Smart (BTLE v.4.2)
        This module is based on BlueNRG-2 , enabling the usage of the embedded Cortex M0 for running the user application code.
        See this presentation.

        • The evaluationboard is: STEVAL-IDB007V1M Bluetooth Low Energy based on BlueNRG-2, enabling the usage of the embedded Cortex M0 for running the user application code
