**BlueNRG-M0 General description** 

## **1 General description** 

The BlueNRG-M0 is a single-mode Bluetooth low energy master/slave network processor module compliant with Bluetooth® v4.2. 

The BlueNRG-M0 module has been designed around the ST BlueNRG-MS network processor, on which a complete power-optimized stack for Bluetooth single mode protocol runs, providing 

- Master, slave role support 

- GAP: central, peripheral, observer or broadcaster roles 

- ATT/GATT: client and server 

- SM: privacy, authentication and authorization 

- L2CAP 

- Link Layer: AES-128 encryption and decryption 

The BlueNRG-MS radio embeds non-volatile Flash memory allows on-field stack upgrading. In addition, according to the Bluetooth specification v4.2, the BlueNRG-M0 module provides: 

- Multiple roles simultaneously support 

- Support simultaneous advertising and scanning 

- Support being slave of up to two masters simultaneously 

- Privacy V1.1 

- Low duty cycle directed advertising 

- Connection parameters request procedure 

- LE Ping 

- 32 bits UUIDs 

- L2CAP connection oriented channels 

The BlueNRG-M0 module is equipped with Bluetooth low energy profiles in C source code, available for the ST radio BlueNRG-MS. 

The external host application processor, where the application resides, is interfaced with the BlueNRG-M0 module through an application controller interface protocol, which is based on a standard SPI interface. 

The BlueNRG-M0 module enables wireless connectivity into electronic devices, not requiring any RF experience or expertise for integration into the final product. The BlueNRG-M0 module provides a complete RF platform in a tiny form factor and being a certified solution optimizes the time-to-market of the final applications. 

The BlueNRG-M0 module allows applications to meet of the tight advisable peak current requirements imposed with the use of standard coin cell batteries. Optimized results are obtained when the embedded high-efficiency DC-DC step-down converter is used (BLUENRG-M0A). Instead, concerning the BLUENRG-M0L the best performance in terms of power consumption is achieved using a 1.8V DC power supply. 

The BlueNRG-M0 can be powered directly with 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.

**BlueNRG-M0 Software architecture** 

## **3 Software architecture** 

## **3.1 Bluetooth firmware implementation** 

The BlueNRG-M0 modules have been designed to work with an external host processor. The external host application processor, where the application resides, is interfaced with the BlueNRG-MS inside the BlueNRG-M0 modules through an application controller interface (ACI) protocol, which is based on a standard SPI slave interface as transport layer, basing on five physical wires: 

- 2 control wires (Clock and “Chip Select") 

- 2 data wires with serial shift-out (MOSI and MISO) in full duplex 

- 1 wire to indicate data availability from the slave (IRQ) 

All the SPI pins have an internal pull-down except for the CS that has a pull-up. All the SPI pins, except the CS, are in high impedance state during the low-power states. The IRQ pin needs a pull-down external resistor.

**BlueNRG-M0 Traceability** 

## **10 Traceability** 

Each module is univocally identified by serial number stored in a 2D data matrix laser marked on the top side (shield) of the module itself. 

Each module bulk is identified by a bulk ID. 

Bulk ID and module 2D data matrix are linked by a reciprocal traceability link. The module 2D data matrix traces the lot number of any raw material used according to following rules: 

**Table 12. Traceability information** 

|**Letter**|**Meaning**|
|---|---|
|HA|Reserved|
|YWW|Year and week number|
|E|Reserved|
|LL|Lot sequence number|
|XX|Lot sub-sequence number|
|0000|Serial number|
