BTM410–411 Development Kit
Quick Start Guide v.1.1
OVERVIEW
This quick start guide for the Laird Technologies OEM BTM41x family Developer Kit (DVK) illustrates how to
read the radio’s configuration and perform a data throughput test between the two radios. For more detailed
information on these steps, refer to the DVK User’s Manual or the radio User’s Manual.
WHAT’S IN THE BOX
BTM41x Development Board
USB Cable
Whip Antenna (only for BTM410)
Bluetooth® USB dongle
Software CD
- EZURiO Terminal
- FTDI USB to RS232 driver
- BTM41x datasheet
- Laird Technologies Bluetooth® line card
Updated datasheets and firmware are available at www.lairdtech.com/wireless.
Additionally, you need a Windows PC running Windows XP SP2 or later.
BLUETOOTH USB DONGLE INSTALLATION
1. Uninstall all third-party Bluetooth stacks, drivers and devices from your PC.
2. Plug the Laird Technologies USB dongle into the PC. Windows XP SP2 detects the device and
opens an installation window.
3. Follow the on-screen instructions to install the standard Microsoft Bluetooth driver.
4. Open the Windows Device Manager.
5. Verify that the Microsoft Bluetooth Enumerator and TDK Bluetooth USB Adaptor are installed.
Figure 1: Microsoft Bluetooth Enumerator and TDK Bluetooth USB Adaptor are present
Note: You must have at least Windows XP SP2 to install the Microsoft Bluetooth 2.0 driver for the Laird
Technologies USB Dongle. Windows Vista SP1 and Windows 7 support Bluetooth 2.1. Microsoft
does not provide a Bluetooth 2.1 driver for Windows XP. Since the USB dongle only supports
Bluetooth 2.0+EDR, it does not have Bluetooth 2.1 functionality on Windows Vista or 7.

DEVELOPMENT BOARD SETUP
1. Connect the USB Cable (used for power and communications) from PC to development board.
a. On the first connection, you must install the USB to RS232 driver. Download the latest WHQL-
qualified driver from www.ftdichip.com.
b. Point the Windows driver install wizard to the location of the downloaded driver.
c. Optionally, you can power the device via 5 V DC.
2. Select the power source via the 3-way switch.
Center = off
DC = power via USB
USB = power via DC
3. Start EZURiO Terminal.
4. Select the correct COM Port (refer to Device Manager, if necessary).
5. Select BAUD rate (default is 9600 bps).
6. Check the CTS LED in EZURiO Terminal. If it is green, it is connected to the correct COM port.
