1. Insert the USB Bluetooth Adapter into your systems USB port. 2. Go to the folder where you installed the Atheros BtUSB tool and double click on BtUSB icon. It launches the software and displays the BtUSB welcome screen with Window command line interface. It also shows the software version, for example, BtUSB_V1_0_B4. See Figure 2-1 for details. At this point you are ready to use the software. Atheros Communications, Inc. COMPANY CONFIDENTIAL Using the BtUSB Tool March 2008 2-1 2-1 2 Chapter Figure 2-1. BtUSB Welcome Screen NOTE: V1_0_B4 is the revision number. This is subject to change. 3. Enter the help command to list available commands.

>help It displays the screen shown in Figure 2-2. Figure 2-2. BtUSB Help Screen 2-2 BtUSB Tool Users Guide 2-2 March 2008 Atheros Communications, Inc. COMPANY CONFIDENTIAL Chapter 2 You can execute any of the commands shown above. Executing BtUSB Commands Getting Help Enter the help command to list available commands. It displays all the commands available. You can also look for help for a particular command as shown below. Usage:

> help <command>

Reading the BD Address Enter rbdaddr or rba at the command prompt to see the BD address of the AR3011:

Usage:

>rbdaddr Setting a new BD Address By entering wbdaddr or wba at the command prompt, you can write a BD address to the AR3011 external EEPROM. Note, the BD address must be in HEX digits and 12 nibbles long. The BD address can be entered after the prompt, as 0xXXXXXXXXXXXX (i.e., 0x00037f402037) or XXXXXXXXXXXX

(i.e., 00037f402037). If the BD address is not entered correctly per the stated format, the BD address will not be accepted, and you will receive an error message (for example, ERROR: Syntax "wba 0x00037F49C0xy" - all 6 bytes). Thus, you must re-enter the BD address in the specified format. Enter the following command to change the Bluetooth Device address:

Usage:

> wbdaddr <BD_Addr>

Enabling Device Under Test Mode By entering the edutm or dut command at the command prompt, you put the AR3011 in DUT mode. Thus, a BT tester can be used with the AR3011 USB device to perform RF tests. Enter the following command to put the Bluetooth Device under test which puts the BD under DUT mode and makes is ready for RF testing:

Usage:

> edutm Atheros Communications, Inc. COMPANY CONFIDENTIAL Using the BtUSB Tool March 2008 2-3 2-3 2 Chapter Initializing EEPROM NOTE: If you have already burnt the latest Atheros image on the EEPROM before placing on the final AR3011 USB design, then execution of this command is optional. By typing initeeprom or ieeprom at the command prompt, the AR3011 onboard flash software image formats and initializes a blank external EEPROM on the AR3011 USB Adapter. During the process, you are asked to enter a BD address. Note, the BD address must be in HEX digits and 12 nibbles long. The BD address can be typed in, after the column, as 0xXXXXXXXXXXXX (i.e. 0x00037f402037) or XXXXXXXXXXXX (i.e. 00037f402037). If the BD address is not entered correctly per specified format, the BD address will not be accepted, and you will receive an error message

(for example, ERROR: Syntax "wba 0x00037F49C0xy" - all 6 bytes Fail). So, in this case, you must restart the initeeprom or ieeprom command again. Enter the following command to EEPROM which is present on the Bluetooth Adapter:

Usage:

> initeeprom <BDADDR>

Resetting the Target NOTE: This command is optional because, when the AR3011 USB Adapter is powered up, it automatically resets. Enter reset or r at the command prompt to reset the AR3011 to an initialized state except for the AR3011 USB interface.

>reset Initiating the Master_Blaster Mode Starting with BtUSB_v1_0_b5 release, a "master blaster" mode has been added where the Atheros Bluetooth device is put under an Atheros proprietary mode in which various types of packets can be transmitted without establishing any Bluetooth link. This is quite useful for testing and board tuning. By typing master_blaster or mb, the master blaster shell is presented where you can make the following selections :

Test Mode (Data pattern : 0101, 11110000, 0000, 1111, PRBS, ...) [use key m]

Enable/disable hopping [use key h]

TX channel (once hopping is disabled) [use key t]

RX channel (once hopping is disabled) [use key r]

Packet Type (DH1, DH3, DH5, 2DH1, .., 3DH5, ..) [use key p]

2-4 BtUSB Tool Users Guide 2-4 March 2008 Atheros Communications, Inc. COMPANY CONFIDENTIAL Chapter 2 Packet Length (DH1, DH3, DH5, 2DH1, .., 3DH5, ..) [use key l. Enter size in bytes]

Transmit Power Level [use key o]

Set BDAddr [use key a]

Once all the parameters have been set to the desired value, press the 'e' key to enable the transmission. If you need to change parameters in the middle of transmit, use any key to stop transmission and make new selection. Get_ID By typing get_id or id, you can obtain useful information to identify the type of chip, firmware build version, radio init, sysconfig version and content information. Reading the IVT LicenseKey This command returns the IVT license key stored in EEPROM. Usage:

>rivtkey or

>rivt Writing the IVT LicenseKey Programs the IVT license key to EEPROM. Usage:

>wivtkey <KEY>

or

>wivt <KEY>

Exporting the Contents of EEPROM to a File Dumps the content of the EEPROM to a file. Usage:

>expeeprom <FILE_NAME>

or

>exp <FILE_NAME>

Importing the Contents of the Given File to EEPROM Programs the EEPROM with the content from the customer specified image file. Atheros Communications, Inc. COMPANY CONFIDENTIAL Using the BtUSB Tool March 2008 2-5 2-5 2 Chapter Usage:

>impeeprom <FILE_NAME>

or

>imp <FILE_NAME>

Comparing the Contents of EEPROM and File Compares the content of EEPROM with a sample image. Usage:

>compeeprom <FILE_NAME>

or

>comp <FILE_NAME>

Formatting the EEPROM Cleans all the settings stored in EEPROM Usage:

>format_eeprom or
