Introduction

The EtherMind Bluetooth SDK provides a software demo package that can be used with the MSP-EXP430F5438 experimenter's board and the PAN1315ETU Bluetooth connectivity board to demonstrate the SPP capability of the MSP430BT5190+CC2560 solution.

This document describes the procedure needed to setup and demonstrate the demo application provided as part of the MSP430BT5190+CC2560 EtherMind SDK.

Setup used for the SPP Demo package:

The demo setup uses two MSP-EXP430F5438 experimenter's boards connected with PAN1315ETU Bluetooth connectivity boards. The MSP-EXP430F5438 boards run the EtherMind stack. It is used to send the accelerometer data on the boards to each other over SPP. One of the experimenter's boards is connected to a PC using a USB connection. The USB driver software running on the PC maps the USB port into an appropriate COM port. The keyboard mapper package software on the PC reads the data from the COM port.

The PAN1315ETU connectivity board is connected at the RF1 & RF2 headers of the MSP-EXP430F5438 experimenter's board. To use the PAN1315ETU board with the MSP-EXP430F5438 experimenter's board, refer the figure below.

Figure 4: Following pins of RF3 needs to be shorted.


Sequence of steps to use the demo package

1. Connect the right pins at the RF3 header on the MSP-EXP430F5438 experimenter's board as explained in Figure 4.

2. Connect the PAN1315ETU board to each MSP-EXP430F5438 at RF1 & RF2 headers. 3. Now connect the Device-2 (Check Figure 2) to PC through USB. Make sure that USB driver for

MSP-EXP430F5438 is installed on the PC using the steps mentioned in USB driver installation section"

4. To power on the devices using USB or battery. a. Place SW1(Power Selector switch) at USB position to supply power using USB b. Place SW1 at BATT position to supply power using batteries

Note: At least one device has to be connected to PC to display the accelerometer data. 5. Ensure that both Device 1 and Device 2 are powered on. 6. Once powered on, Bluetooth and device visibility is turned on automatically.

The LED indications are explained below:

LED Status Meaning

Blinking Bluetooth powering on in progress

ON Bluetooth powered ON LED1 (RED)

OFF Bluetooth powered OFF

Blinking Inquiry and Page Scan mode entered. Waiting for S1 key press on either device

ON SPP data is being transferred LED2

(YELLOW)

OFF Initial condition before Bluetooth is switched ON

7. LED1 starts blinking during initialization (red) and moves to solid ON after initialization is

completed. 8. Inquiry and page scan mode is indicated by flashing of LED2 (Yellow). 9. PressS1ondevice1ordevice2forthelinktogetestablished.10. It starts looking for the devices starting with the name BlueMSPDemo and connects to it

automatically. It takes approximately 10-15 seconds to connect. 11. Once link is established, LED2 turns to solid ON state (Yellow) and both the devices stop any type

of scan and visibility is turned off. Accelerometer data readings are then sent over SPP in sniff mode between the two devices. Device1 sends data to Device2 and vice-versa.

12. Configure this com port on the PC side as explained in the section Configuring COM Port. Run the keyboard event-mapper package on the PC. If no valid MSP COM ports are found on the device, the user is allowed to manually override and provide the port number through the com_port.txt file, placed in the current directory. The display will appear as below:


13. If one or more valid MSP COM ports are found on the machine, the user is prompted to choose the

port, or manually override and provide the port number through the com_port.txt file, placed in the current directory. The selected port is used for the connection and the application displays the data received on this port. Once the 2D-accelerometer data is received over the SPP connection, the application maps it to the right/left/up/down key events of the PC and also prints the SPP data on the console. The display will appear as shown below:

14. Install and run the PlanetPenguin Racer game. The game play can be controlled using the accelerometer on Device-1.

a. NOTE: Any application which takes UP/DOWN/LEFT/RIGHT as input and these events can be controlled using the accelerometer on device-1.

15. SPP data transfer from any device can be paused or resumed by pressing the switch SW2 on that particular device.


USB driver installation for MSPEXP430F5438 Experimenter Board

For USB communication with the MSPEXP430F5438 Experimenter Board, a serial communication driver is necessary. To properly install the driver, follow these steps:

1. Download the driver (swrc094.zip) from http://focus.ti.com/docs/toolsw/folders/print/tusbwinvcp.html

2. Run setup.exe and complete the "TUSB3410 Single Driver Wrapper InstallShield Wizard." This extracts the driver files and installer into the Program Files directory.

3. Navigate to the installation directory (by default it is C:\Program Files\Texas Instruments Inc\TUSB3410 Single Driver Installer\DISK1) and run setup.exe. Complete the "TUSB3410 Install Shield Wizard" to install the drivers.

4. Plug in the mini-USB cable to the mini-USB port on the MSP-EXP430F5438 board (see Figure 3). Plug in the other end of the cable to a USB port on the host PC.

5. To ensure that the USB driver installation was successful, open Device Manager under Start>Control Panel>System>Hardware>Device Manager. There should appear a MSP-EXP430F5438 USB Serial Port (COMxx) entry under "Ports (COM & LPT)" (the xx in COM identifies the enumeration of the COM port).


Configuring COM PORT

Right click on My Computer icon and select the Properties option from the drop down menu.

In the Properties menu, select the Hardware tab Device Manager option as shown below:


In the Device Manager window expand the Ports option and in the expanded list of ports, right click on the desired MSP430 port and click on the Properties option as shown below:


In the Properties window select the Port Settings tab and configure the port with the values shown below:
