1. Functional Overview

This chapter describes the functional overview of all the applications that are pre-defined in Atmel Studio.

1.1 Proximity Reporter Application

The Proximity profile is defined by the Bluetooth® SIG to enable proximity monitoring between two
Bluetooth Low Energy (BLE) devices. The Proximity Monitor (a Generic Attribute (GATT) client)
configures the behavior of the peer Proximity Reporter device (a GATT server) based on the link
conditions. The configuration includes setting the alert level, which triggers on the Link Loss or based on
a different threshold of the Path Loss. The Path Loss determines the quality of the connection and it is
derived out of the Received Signal Strength Indicator (RSSI). The Proximity Monitor continuously
evaluates the Path Loss and creates an immediate alert in the Proximity Reporter device when the Path
Loss crosses threshold values.

On-Board LED Status

The on-board LED is configured to notify the user about the alerts received. The different alerts for the
Link Loss and Immediate Alert services are explained in the following subsections.

ATWINC3400

Functional Overview

Link Loss

On the Link Loss, the LED blinks according to the alert level set by the Proximity Monitor. The alert levels
are:

• NO_ALERT for No alert level

• MILD_ALERT for Mild alert level

• HIGH_ALERT for High alert level

Based on the alert level configuration set by the Proximity Monitor, the LED blinks at different rates:

• If the alert level is “HIGH_ALERT” then the LED blinks faster (1 second interval)

• If the alert level is “MILD_ALERT” then the LED blinks moderately (2 second interval)

• If the alert level is “NO_ALERT” the LED must be off

Alert on Path Loss (Immediate Alert)

This alert is applicable when the “Immediate Alert” service is implemented. The example application relies
on the Path Loss configuration done by the Proximity Monitor and notifies accordingly. The alert levels
are:

• NO_ALERT for No alert level

• MILD_ALERT for Mild alert level

• HIGH_ALERT for High alert level

Based on the alert level configuration set by the Proximity Monitor, the LED blinks at different rates:

• If the alert level is “HIGH_ALERT” then the LED blinks faster (3 second interval)

• If the alert level is “MILD_ALERT” then the LED blinks moderately (5 second interval)

• If the alert level is “NO_ALERT” the LED must be off

1.2 Battery Service Application

The Battery Service application is used for reporting the battery level of the device using the battery
characteristics. Any application discovering the database can access the battery service instance during

User Guide

DS50002706A-page 5

discovery services. This example application simulates the device battery level from 0% to 100%, with the
step of 1% every second.

1.3 Custom Serial Chat Profile Application

The Custom Serial Chat application is used for sending and receiving data between the boards (SAM
D21) and the Microchip SmartConnect mobile application. This is a custom profile example application
implemented over GATT. The user can send the information to the mobile phone using the console
terminal that is configured with the board and vice versa.

1.4 Heart Rate Profile Application

The Heart Rate Profile application is used for enabling the collector device (GATT client) to connect and
interact with a heart rate sensor (GATT server) to be used in the fitness applications. The heart rate
sensor sends the heart rate measurement in bpm (beats per minute), energy expended in kJ (kilojoules),
and R-R intervals in seconds. In addition to the heart rate service, this profile also implements the Device
Information Service, which provides information about the heart rate sensor device.

The heart rate profile provided by Bluetooth SIG defines three characteristics for the exchange of heart
rate parameters between the sensor and monitor. The characteristics of the profile are used to transfer
heart rate parameters like bpm, R-R interval measurements, and other parameters like body sensor
location and energy expended values. The optional “Heart Rate Control Point characteristic” is used by
the heart rate monitor to reset the energy expended in the heart rate sensor.

ATWINC3400

Functional Overview

The heart rate sensor, which is the GATT server, holds the characteristics and sends the measurement
values to the heart rate monitor.

• The heart rate, R-R interval, and energy expended are sent using the heart rate measurement
characteristics.

• The heart rate measurements are sent to the monitor on a value change if the monitor has enabled
the notifications.

• The body sensor location is read by the monitor by its body sensor location characteristic. The
energy expended sent in the heart rate measurement can be reset by the monitor by writing to the
heart rate control point characteristic.

Note:  The example application simulates the sensor measurements and sends them to the heart rate
collector.

1.5 Transparent Service Application

The Transparent Service is used as a data exchange method between the client and the server.

• Transparent Tx characteristic is used for data transmission by the server or client. Once the Client
Characteristic Configuration Descriptor of Transparent Tx is enabled, the server sends data to the
client by this channel. The client also can send the data through this channel.

• Transparent Rx characteristic is used for data transmission by the client. The client can send data
to the server by this channel.

• Transparent Control Point characteristic: To ensure successful operation, this Client Characteristic
Configuration Descriptor of Transparent Control Point (TCP) must be enabled to notify. The client
must perform a write to the TCP to execute a desired procedure at the server. The Transparent
Control Point is used by a client to control certain behaviors of the server. The procedures are

User Guide

DS50002706A-page 6

triggered by writing a value that includes an Op code specifying the operation and the server
notifies of the result of the operations.

When enable credit-based flow control Op code is written to the TCP, the server responds with the
maximum MTU size and available credit to the client. The number of credits are checked by the client to
know how many data lists can be transmitted to the server. The number of credits are decreased by the
list of data sent by client. The client can only send data while the number of credits is non-zero. The
server returns the credit to the client after the server finishes dealing with the received data.

1.6 On-chip Provisioning Application

The On-chip Provisioning application is used for receiving Wi-Fi provisioning data via Bluetooth and then
triggering a Wi-Fi connection. The majority of the provisioning functionality is performed by the BLE
Cortus of ATWINC3400, with the host application performing some helper functions via dedicated
libraries. This application triggers a Wi-Fi scan and lists the scanned APs on the receiver. On receiving
the Wi-Fi configuration data (which is passed to the host application where it is fed into the BLE Cortus
provisioning API), it validates the data and starts the connection process. On successful connection, the
Bluetooth connection is terminated. If the connection is not successful with received configuration, the
provisioning process restarts and lists the latest scanned APs again.

Microchip Devices Code Protection Feature

Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the
market today, when used in the intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of
these methods, to our knowledge, require using the Microchip products in a manner outside the
operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is
engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their
code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the
code protection features of our products. Attempts to break Microchip’s code protection feature may be a
violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software
or other copyrighted work, you may have a right to sue for relief under that Act.
