1. FCC Rules

1.1. List of FCC rules

The SHARKY module have received Federal Communications Commission (FCC) CFR47

Telecommunications, Part 15 Subpart C “Intentional Radiators” single-modular approval in

accordance with Part 15.212 Modular Transmitter approval.

According to FCC Part 15.212 the single-modular transmitter is a completely self-contained

radiofrequency transmitter device that is typically incorporated into another product, host or

device and complies to all the conditions to be defined as a “single modular transmitter”.

The Midatronics SHARKY Modular Transmitter is also compliant to FCC Part 15.247 insofar

as it is a device using a wide band modulation inside the band 2400-2483.5 MHz with a 6dB

bandwidth greater than 500kHz.

2. Introduction

2.1. Description

This document describes the Sharky modules.

Sharky is a complete family of modules that enables customer to test and integrate the new

STM32WB MCU for rapid prototyping and fast time to market.

Sharky modules are based on STMicroelectronics STM32WB55CE, a dual-core MCUs with

wireless support based on an Arm® Cortex®-M4 core running at 64 MHz (application

processor) plus an Arm® Cortex®-M0+ core at 32 MHz (network processor).

With two totally independent cores, this innovative architecture is optimized for real-time

execution (radio-related software processing).

The STM32WB55 Bluetooth 5.0-certified device offers Mesh 1.0 software support, multiple

profiles and flexibility to integrate proprietary BLE stacks.

OpenThread-certified software stack is available. The radio can also run BLE/OpenThread

protocols concurrently. The embedded generic MAC allows the usage of other IEEE 802.15.4

proprietary stacks like ZigBee®, or proprietary protocols, giving even more options for

connecting devices to the Internet of Things (IoT).

The Sharky module is available in four versions:

●Sharky with PCB Antenna

●Sharky with uFL connector

Sharky modules are sold standalone or soldered on a breakout board for easy connections.

3. System Overview

3.1. BLE Technology Overview

Bluetooth Low Energy (BLE) is the main feature of the Bluetooth specification v4.0 released

in December 2009. BLE is a new protocol that allows for long-term operation of Bluetooth

devices that transmit low volumes of data. BLE enables smaller form factors, better power

optimization, and the ability to operate on a small power cell for several years.

The classic Bluetooth specification defines a uniform structure for a wide range of devices that

connect to each other. Bluetooth operates primarily using ad hoc piconets. A master device

controls up to seven slaves per piconet; the slaves communicate with the master device but

they do not communicate with each other. However, a slave device may participate in one or

more piconets, essentially a collection of devices connected via Bluetooth. A summary of

classic Bluetooth topology with multiple piconets, called scatternet, can be found below.

Figure 1. Bluetooth Scatternet topology

In a BLE topology, the slaves each communicate on a separate physical channel with the

master. Unlike a classic Bluetooth piconet, where all slaves listen for incoming connections

and therefore need to be on constant standby, a BLE slave invites connections and so is in

total control of when to consume power. A BLE master, which is assumed to have less power

constraints, will listen for advertisements and make connections on the back of an

advertisement packet. A diagram of this can be found below.

Figure 2. BLE Sta

-bus Topology

While BLE inherits the operating spectrum and the basic structure of the communication

protocol from the classic Bluetooth protocol, BLE implements a new lightweight Link Layer

that provides ultra-low power idle mode operation, fast device discovery, and reliable and

secure point-to-multipoint data transfers. As a result, BLE offers substantially lower peak,

average, and idle-mode power consumption than classic Bluetooth. Averaged over time, BLE

consumes only 10% of the power consumed by classic Bluetooth.

In addition to its ultra-low power consumption, BLE has several unique features that set it apart

from other available wireless technologies, including:

●Interoperability: Like classic Bluetooth devices, BLE devices follow standards set by

the Bluetooth Special Interest Group (SIG), and BLE devices from different

manufacturers interoperate.

●Robustness: BLE uses fast frequency hopping to secure a robust transmission even

in the presence of other wireless technologies.

●Ease of Use: BLE has been developed so that it is straightforward for designers to

implement it in a variety of different applications.

●Latency: The total time to send small chunks of data is generally fewer than 6 ms, and

as low as 3 ms (compared to 100 ms with classic Bluetooth).

●Range: Thanks to an increased modulation index, BLE technology offers greater range

(up to 200 feet and beyond, in ideal environments) than to classic Bluetooth offers.

3.2. BLE Mesh Technology overview

Figure 3. BLE Mesh Topology

Borrowing from the original Bluetooth specification, the Bluetooth SIG defines several profiles

— specifications for how a device works in a particular application — for low energy devices.

Manufacturers are expected to implement the appropriate specifications for their device in

order to ensure compatibility. A device may contain implementations of multiple profiles.

Majority of current low energy application profiles is based on the generic attribute profile

(GATT), a general specification for sending and receiving short pieces of data known as

attributes over a low energy link. Bluetooth mesh profile is the exception to this rule as it is

based on General Access Profile (GAP).

Bluetooth mesh profiles use Bluetooth Low Energy to communicate with other Bluetooth Low

Energy devices in the network. Each device can pass the information forward to other

Bluetooth Low Energy devices creating a "mesh" effect. For example, switching off an entire

building of lights from a single smartphone.

Conceptually, the Bluetooth Mesh Standard is defined as a publish/subscribe model where

publishers can publish to a certain topic and subscribers can subscribe to one or more topics

of interest.

This concept is used as an inspiration for the implementation in the standard. A node in a

Bluetooth Mesh network can subscribe to one or more addresses (stored in the subscriber

list) and publish to one specific address (stored in the publish address).

pag. 10 of 38

To be able to connect these different publishers and subscribers, a mesh topology is created.

The standard uses BLE advertising and scanning as an underlying technology to implement

communication. To communicate in a Bluetooth Mesh network, a flooding mechanism is used.

By default, a flooding mechanism ensures that each node in the network repeats incoming

messages, so that they are relayed further, until the destination node is reached.

The standard uses a new type of BLE advertisement packet to communicate in a mesh

network, which is only supported by devices that support both BLE and Bluetooth Mesh.

Fortunately, the standard also defines a backwards compatibility feature to ensure that BLE

devices which do not support Bluetooth Mesh can also be part of a Bluetooth Mesh network.

3.3. Thread Technology overview

Thread is a secure, wireless mesh networking protocol. The Thread stack is an open

standard that is built upon a collection of existing Institute for Electrical and Electronics

Engineers (IEEE) and Internet Engineering Task Force (IETF) standards.

The Thread stack supports IPv6 addresses and provides low-cost bridging to other IP

networks and is optimized for low-power/battery-backed operation, and wireless device-

to-device communication. The Thread stack is designed specifically for Connected Home

applications where IP-based networking is desired and a variety of application layers can

be used on the stack.

These are the general characteristics of the Thread stack focused on the Connected

Home:
