1.0 Installation
1.1 INSTALL SIMPLY BLUE COMMANDER
The Simply Blue Commander is an easy to use application which enables you to send single commands to the
LMX9830/LMX9838 Evalboard. The built-in command and event interpreter generates an easy to read log of the UART
traffic between the application and the LMX9830/LMX9838.
For the installation of the program please refer to the “Simply Blue Commander User Guide”. After installation please make
sure the connection between PC and Board is set up and working. The screen should come up like shown in Figure 1-1
(screens shown are for LMX9838).
Figure 1-1. Simply Blue Commander
1.2 INSTALL IVT BLUETOOTH STACK
In case you do not have any other Bluetooth device for testing, each LMX9830/LMX9838 Evaluation board includes
one BT USB Dongle. This dongle is a standard Bluetooth USB dongle.
In order to be able to work with a HCI based dongle, a host stack (windows stack) has to be installed on your PC. The
dongle is shipped with the IVT Windows stack.
Please insert the CD delivered with the BT USB Dongle and follow the instructions of the setup. After the installation
please plug the dongle into an available USB port. The PC should detect the dongle and install the necessary drivers.
Afterwards the stack is ready and should show up as the picture below. The task bar should include a blue/white colored
Bluetooth sign.
NOTE: The IVT Stack is only necessary in combination with the Bluetooth USB Dongle. which can be used as counterpart for the LMX9830/LMX9838. It is not necessary to drive the LMX9830/LMX9838.

1.3 SETTING UP HYPERTERMINAL
Simple serial port data transfers can be done by using a standard serial port terminal program like the Microsoft Hyperterminal. The program is part of Windows XP.
Some of the demonstrations later on are based on hyperterminal. For this, please make sure Hyperterminal or a similar terminal program is available on the system.
You’ll find hyperterminal within the Windows environment within the Start Menu under “Start/All Programs/Accessories/
Communication”. Please see Figure 1-3 where to find “Hyperterminal”.
Hyperterminal is not any longer offered with new operating systems like Windows Vista, 7 or 8. In such a case putty or
some other free terminal programs can be used.

LMX 98xx Bluetooth Serial Port Modules - Quick Setup Guide
2.0 Setup descriptions
The LMX9830/LMX9838 is a full Bluetooth node, by default configured to listen for incoming links. The command
interface also offers the ability to configure the device and actively setup links.
The following examples shall give an quick introduction into the different functionalities of the LMX9830/
LMX9838.
2.1 CABLE REPLACEMENT WITH LMX9830/LMX9838 WAITING FOR INCOMING CONNECTION
By default the LMX9830/LMX9838 is configured to be visible (discoverable) and connectable for other devices. The
service database offers one “Serial Port Profile” (SPP) service called “COM1”.
In case the LMX9830/LMX9838 is connected by a remote device it will indicate the incoming link by a short event on
the UART and then switch to transparent meaning it will not try to interpret incoming data on the UART directly to the
Bluetooth interface. Incoming data on the Bluetooth interface are directly routed to the UART interface without framing
them into Simply Blue command packets.
The demo is based on using Hyperterminal on both sides to create a simple serial port connection between two devices
using the USB dongle as connecting device and LMX9830/LMX9838 as ‘passive’ waiting device.
2.1.1 Connect Hyperterminal to LMX9830/LMX9838
Since the LMX9830/LMX9838 is waiting for an incoming connection automatically, no specific action has been taken on
this side. In order to monitor the incoming data on the UART any terminal program able to talk to a serial port can be used.
This example uses the Hyperterminal application.
The following steps should be followed to connect “Hyperterminal” to the LMX9830/LMX9838 Evaluation Board.
2.1.1.1 Start Hyperterminal
Start Hyperterminal as described in Section 1.3. Please make sure no other application (e.g. Simply Blue Commander) is
using the same port as the LMX9830/LMX9838 Evaluation Kit.
2.1.1.2 Create new connection
Create a new connection by typing a connection name like “SBDemo LMX9838”.

2.1.1.4 Choose comport settings
Choose the correct comport settings for your LMX9830/LMX9838 Evaluation board. For example, we configure the UART
setting on the board and the PC to 115200 bit/s, No Parity, 1 Stop bit. Please make sure Hardware Flow Control is selected in the dialog.
The LMX9830 UART setting is done by configuring pins OP3, OP4 and OP5. The setting for 115200 bit/s is OP3=1, OP4=1
and OP5=0
The LMX9838 UART setting is done by configuring pins OP4 and OP5. The setting for 115200 bit/s is OP4=1 and OP5=0

2.1.1.5 Reset the LMX9830/LMX9838 Evaluation Board
Once the correct speed is chosen “Hyperterminal” should connect to the selected comport. Afterwards a hardware reset of
the LMX9830/LMX9838 Evaluation board should cause a response as shown in Figure 2-4. The cryptic characters are specific hex values which are part of the Simply Blue interface event. The “0212” indicates the firmware version
which might be different to your board. Please refer to “LMX9830 or LMX9838 Software Users Guide” for a detailed
description of this event.
If this event is received the communication between “Hyperterminal” and the LMX9830/LMX9838 Evaluation
board is confirmed.

2.1.2 Establish Link to the LMX9830/LMX9838 from the Bluetooth USB Dongle
Since the LMX9830/LMX9838 is by default connectable and discoverable, it can be connected from any other Bluetooth device. To establish the link from the BT USB Dongle, the IVT Stack needs to be started. Therefore please start the
“Bluesoleil” application. You should see the screen as demonstrated in Figure 1-2 on page 4. The Bluetooth icon in
the taskbar needs to be blue and white. In case the background is grey instead of blue, the USB dongle has not been
installed correctly.
2.1.2.1 Start Inquiry - Search for devices in range
The first to be done is to search for the devices in range. To do so, please click on the yellow “sun” in the middle of the
window, which initiates the Bluetooth “Inquiry”. The LMX9830/LMX9838 Evaluation board should appear as “Serial Port
Device”.

Figure 2-7. Connect to the Bluetooth serial port
As result the stack will report the virtual serial port, which will be used for this serial port connection. In this example
“COM4” will be used. This means, any data sent to this COMPort will be sent over the Bluetooth link to the LMX9830/
LMX9838.
If the dialog is answered with Yes, the stack will automatically open the Bluetooth link to the LMX9830/LMX9838 as soon as
any application opens “COM4”.
Please confirm with “Yes” if that’s desired. Otherwise the assignment of COM4 to the LMX9830/LMX9838 will be
temporary.

2.1.2.4 Enter PIN for LMX9830/LMX9838
By default the LMX9830/LMX9838 asks for a PIN if the local SPP service is connected from a remote device.
Therefore the following dialog will appear from the IVT Stack. Please type “0000”, which is the default PIN stored in the
LMX9830/LMX9838 and press OK.
Figure 2-9. Enter PIN for LMX9830/LMX9838
Afterwards the Link between the two devices is established. The IVT Stack indicates the link by showing a line between the
“sun” and the “Serial Port Device” icon.
