The SPBTLE-RF0 module integrates the BlueNRG-MS BT radio controller with an on-board power-optimized Bluetooth stack. It supports: • Both master and slave roles • GAP: central, peripheral, observer or broadcaster roles • ATT/GATT: client and server • SM: privacy, authentication and authorization • L2CAP The BlueNRG-MS radio embeds nonvolatile Flash memory which allows on-field stack upgrading. In accordance with Bluetooth specification v4.1, the SPBTLE-RF0 module supports: • Multiple simultaneous roles • Simultaneous advertising and scanning • Acting as slave for up to two masters simultaneously • Privacy V1.1 • Low duty cycle directed advertising • Connection parameter request procedure • LE Ping • 32 bits UUIDs • L2CAP connection oriented channels Both standard and proprietary Bluetooth low energy profiles, as well as a wide set of examples are available for the SPBTLE-RF0 from the ST website. The external host application processor where the application resides is interfaced with the SPBTLE-RF0 module through an application controller interface protocol based on a standard SPI interface. With the SPBTLE-RF0 module, developers can enable wireless connectivity in electronic devices without requiring any RF experience or expertise for integration into the final product. The SPBTLE-RF0 module provides a complete RF platform in a tiny form factor (13.5 x 11.5 x 2 mm) and, being a certified solution, optimizes the time to market of the final applications. The SPBTLE-RF0 module allows applications to meet the tight peak current requirements when using standard coin cell batteries. SPBTLE-RF0 can be powered directly from a standard 3 V coin cell battery, a pair of AAA batteries or any power source from 1.7 to 3.6 V. ST may update the FW provided with the modules at any time. ST recommends that users regularly check for documentation and the current FW version available at www.st.com/bluemodules.

In particular the SPBTLE-RF0 module is configured with: • 32 MHz crystal oscillator • 32 KHz Ring Oscillator • Internal LDO ( SMPS Off) From the prebuilt image files provided for the BlueNRG-MS Development Kit, only the files with “32MHz”, “RO32K”, and “SMPS_OFF” in the file name are suitable for the SPBTLE-RF0. For example only the ifr_3v1_003_mode02-32MHz-RO32K_SMPS_OFF.dat file is suitable for the SPBTLE-RF0. When used with the BlueNRG-GUI, the IFR configuration settings should reflect those pictured below. Figure 2.
