Demo Overview

Note: The same instructions can be used to run this demo on the Tiva, MSP432 or STM32F4 Platforms.

The phone alert state profile (PASP) is used to notify the Client about the Alert and Ringer Status of the Server device. There are two roles defined in this profile, Server and the Client. Any changes made to the alert or Ringer status is also notified by the Server to the Client. The Client may also request the Server to put the phone into Silent mode and bring it out of Silent mode.

This application allows the user to use a console to use Bluetooth Low Energy (BLE) to establish connection between two BLE devices, change phone alert status, change ringer status, put in and get out of silent mode.

It is recommended that the user visits the kit setup Getting Started Guide for MSP430, Getting Started Guide for TIVA, Getting Started Guide for MSP432 or Getting Started Guide for STM32F4 pages before trying the application described on this page.

Running the Bluetooth Code

Once the code is flashed, connect the board to a PC using a miniUSB or microUSB cable. Once connected, wait for the driver to install. It will show up as MSP-EXP430F5438 USB - Serial Port (COM x), Tiva Virtual COM Port (COM x), XDS110 Class Application/User UART (COM x) for MSP432, under Ports (COM & LPT) in the Device manager. Attach a Terminal program like PuTTY to the serial port x for the board. The serial parameters to use are 115200 Baud (9600 for MSP430), 8, n, 1. Once connected, reset the device using Reset S3 button (located next to the mini USB connector for the MSP430) and you should see the stack getting initialized on the terminal and the help screen will be displayed, which shows all of the commands.

Demo Application

The demo application provides a description on how to use the demo application to connect two configured boards and communicate over Bluetooth LE. The included application registers a custom service on a board when the stack is initialized.

Device 1 (Server) setup on the demo application

a) To start with one of the devices has to have the Phone Alert Status running on it. It can be started by running RegisterPASS.

b) Next, the device acting as a Server needs to advertise to other devices. This can be done by issuing the AdvertiseLE 1 command.

Device 2 (Client) setup on the demo application

Note: Steps c and d are optional if you already know the Bluetooth address of the device that you want to connect to.

c) The Client LE device can try to find which LE devices are in the vicinity issuing the StartScanning command.

d) Once you have found the device, you can stop scanning by issuing the StopScanning command.

Initiating connection from device 2

e) Once the application on the Client side knows the Bluetooth address of the device that is advertising, it can connect to that device issuing the ConnectLE <Bluetooth Address> command

Identify supported services

f) After initialization, the Client needs to find out whether PASS services are supported and what PASS features are available. For this, issue the DiscoverPASS command on the Client. After the service discovery operation is complete, the PASS Service Discovery Summary and list of supported features is shown.

g) After getting the list of supported features, the next step is to configure the PASS on the Client. We can set the configuration for Alert Status Notify and Ringer Settings.

h) In this case, both Alert Status Notify and Ringer Setting Notify are enabled by issuing the ConfigureRemotePASS <Alert status notify> <Ringer Setting Notify>

Alert Notification between Client and Server

i) After configuring, The Phone Alert System is now active. We can get the status of the Alert and Ringer by issuing the NotifyAlertStatus and NotifyRingerSetting commands.

After running NotifyAlertStatus and NotifyRingerSetting on the Server, we get the Alert Status and Ringer Setting on the Client.

j) We can set the Alert Status for each of the three options (Display, Vibrate and Ringer) by issuing the SetAlertStatus <Ringer> <Vibrate> <Display> command and setting each option either active or inactive.

In this example, we set all of them to active and then issue the NotifyAlertStatus command.

The Client will then receive the updated alert status.

k) Similarly, we can toggle the ringer setting between Silent and Normal through SetRingerSetting.

In our example, we set toggle between Normal and Silent settings and update the setting by issuing the NotifyRingerSetting command.

The Client sees the updated Ringer settings.

We can also move the device into and out of silent mode by issuing the SetSilentMode and CancelSilentMode commands and Mute the device by issuing the MuteOnce command.

Application Commands

TI’s Bluetooth stack is implementation of the upper layers of the Bluetooth protocol stack. TI’s Bluetooth stack provides a robust and flexible software development tool that implements the Bluetooth Protocols and Profiles above the Host Controller Interface (HCI). TI’s Bluetooth stack's Application Programming Interface (API) provides access to the upper-layer protocols and profiles and can interface directly with the Bluetooth chips.

An overview of the application and other applications can be read at the Getting Started Guidefor MSP430, Getting Started Guide for TIVA M4, Getting Started Guide for MSP432 and Getting Started Guide for STM32F4.

This page describes the various commands that a user of the application can use. Each command is a wrapper over a TI’s Bluetooth stack API which gets invoked with the parameters selected by the user. This is a subset of the APIs available to the user. TI’s Bluetooth stack API documentation (TI_Bluetooth_Stack_Version-Number\Documentation or for STM32F4, TI_Bluetooth_Stack_Version-Number\RTOS_VERSION\Documentation) describes all of the API's in detail.

GAP Commands

The Generic Access Profile defines standard procedures related to the discovery and connection of Bluetooth devices. It defines modes of operation that are generic to all devices and allows for procedures which use those modes to decide how a device can be interacted with by other Bluetooth devices. Discoverability, Connectability, Pairability, Bondable Modes, and Security Modes can all be changed using Generic Access Profile procedures. All of these modes affect the interaction two devices may have with one another. GAP also defines the procedures for how bond two Bluetooth devices.

The following function is provided to allow a means of performing a write without response request to remote device for a specified attribute. The first parameter to this function is the Bluetooth stack ID of the local Bluetooth stack, followed by the connection ID of the connected remote device, followed by the handle of the attribute to write, followed by the length of the value data to write (in bytes), followed by the actual value to write. This function will return the number of bytes written on success or a negative error code.

CancelSilentMode

Description

Parameters
It is not necessary to include parameters when using this command. A parameter will have no effect on the outcome of the command.

Possible Return Values
(0)Cancel Silent Mode command request sent
(-4) FUNCTION_ERROR

API Call
GATT_Write_Without_Response_Request(BluetoothStackID, ConnectionID, DeviceInfo->ClientInfo.Ringer_Control_Point, PASS_RINGER_CONTROL_POINT_VALUE_LENGTH, ((void *)CommandBuffer)
