l i Q u c k S e t u p G u d e i 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 counter-

part for the LMX9830/LMX9838. It is not necessary to drive the LMX9830/LMX9838. Revision 1.3 3 www.ti.com i e d u G p u t e S k c u Q i

l s e u d o M t r o P l a i r e S h t o o t e u B x x 8 9 X M L l 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.

l s e u d o M t r o P l a i r e S h t o o t e u B x x 8 9 X M L l 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 select-

ed 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 Figure 2-3.

l i Q u c k S e t u p G u d e i 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 char-

acters 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. Figure 2-4.

tooth 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 2-5.

l i Q u c k S e t u p G u d e i INITIATE A LINK WITH LMX9830/LMX9838 USING SIMPLY BLUE COMMANDER 2.2 The LMX9830/LMX9838 command interface offers full Bluetooth capabilities. The Simply Blue Commander software gives an easy to use interface to send commands to the LMX9830/LMX9838 and interprets incoming events. Please see also Simply Blue Commander Users Guide for a detailed description on the usage of Simply Blue Comman-

der. The following demonstration shows how to use Simply Blue Commander to establish a standard Serial Port Profile (SPP) Link to another device. The counterpart of the link will be the BT USB Dongle, controlled by the IVT Stack. Please make sure the devices are connected to the PC and the IVT stack at the PC detected the USB Dongle correctly. 2.2.1 Start Simply Blue Commander Start Simply Blue Commander as described inSection 1.1 on page 3. Please make sure no other device is using the Comport the LMX9830/LMX9838 Evaluation board is connected to. Once the program is up and running, press the RESET button on the Evaluation board. This will cause the LMX9830/

LMX9838 to reboot and bring up the SimplyBlue Ready Event, followed by the firmware version. Figure 2-18. Simply Blue Commander Start Window Revision 1.3 19 www.ti.com i e d u G p u t e S k c u Q i

General Inquiry to get the Bluetooth address of a remote device 2.2.3.2 Get remote name (optional) In case more than one device has been found, each of the devices can be asked for its Friendly Name. As seen in Section 2.1.2.1 on page 10, the LMX9830/LMX9838 by default appeared as Serial Port Device. To get the remote name of the device in our example, the device needs to be contacted and asked for its name. The name request is initiated by the Remote Name Request Command within the Command Directory. Since the command needs to be modified for each specific device, the following procedure needs to be followed for each device. 2.2.3.2.1 Single Click Remote Name Request By single clicking the Remote Name Request Command, the HEX/ASCII input line is updated with the complete hex string to be sent to the LMX9830/LMX9838.

Each command is built out of a 6-byte header, the payload and a 1-byte delimiter. The payload of the command by default is filled with FF as placeholder for the remote Bluetooth device address. To initiate the remote name request, the Bluetooth device address from the previous inquiry result needs to be filled in. The address can be found within Transport Layer log, reported as RX:Event: Device Found, BdAddr: 015814170008, Device Class: 040112 In this example the inquiry just indicates one device with address 015814170008. To complete the request this address has to be filled into the HEX/ASCII input link, by replacing the FFs with this address.

The LMX9830/LMX9838 will respond to the request by the appropriate Remote Device Name Event, including the status and the device name. In this example the name DCDL38 has been detected. In case the status is different from 0x00, the physical connection establishment might have been failed. In that case just try again until the status 00 is reported. Figure 2-23. Remote Name Request Response 2.2.4 Get remote RFComm Port for SPP A serial port profile communication between two devices is based on the RFCOMM layer. This layer basically offers a vir-

tual serial port environment to the application. Each SPP based service like Serial Port or Dial Up Networking is regis-

tered to a specific RFCOMM port, like e.g. a modem driver on a PC is using a specific COMport. This comport assignment is stored within the so called Service Database of each device. If a device wants to create a link to the Serial Port service of another device, it has to know the RFComm Port for this ser-

vice on the other device. Afterwards a link will be established from a Local Port to the appropriate Remote Port. The RFCOMM Port of a service on the remote device can be found by using a SDAP Request. 2.2.4.1 Create SDAP Connection To browse for service first a SDAP connection has to be established. For this the SDAP Connect Command can be used. Since the command needs to be modified for the correct Bluetooth address, the same procedure as for the Remote Name Request needs to be used. 2.2.4.1.1 Single Click SDAP Connect in the Command Directory By a single click of the command in the directory, the hex string for the command appears in the HEX/ASCII input: line. www.ti.com 24 Revision 1.3 l L M X 9 8 x x B u e t o o t h S e r i a l P o r t M o d u e s

Select Establish SPP Link 2.2.5.2 Adapt Link Establishment parameters The Establish SPP Connection command includes 3 parameters in the payload, which have to be adapted to successfully establish a link. As usual the first 6-bytes of the command are the packet header. The payload of the command in the example consists of:

The Local RFCOMM Port (1 byte) This is the local RFCOMM port of the LMX9830/LMX9838, which will be assigned to this link. Each data sent to this port after link establishment will be sent to this remote Bluetooth device. The BD_Addr of the remote device (6 bytes) In able to connect to the correct device, its BD_Addr has to be filled in (same as used for SDAP, found by Inquiry) The Remote RFCOMM Port (1 byte) The remote RFCOMM port is the comport assigned to the Serial port service, as found by the SDAP Service Browse

If status is different from 00 then please check again the parameters youve entered within the com-

mand. The IVT stack of the USB Dongle will probably alert to the user that another device tries to request the service and will ask for the PinCode. For this the default pincode of the LMX9830/LMX9838 needs to be used (0000). Figure 2-31.

i Q u c k S e t u p G u d e i In case the Pincode has been entered correctly, the stack asks if again on application level if the device is allowed to access the Serial Port Service. The question should be answered with Yes. To avoid this message in the future, the check-

box can be checked as well. Figure 2-32. Incoming device requesting access to a local service Finally the stack reports virtual serial port which can be used to send and receive data for the connected device. This port can now be used by applications like hyperterminal. NOTE: The IVT stack and most other windows stacks assign different virtual ports for incoming and outgoing connections. Figure 2-33. Virtual Serial Port for the incoming link Having a final look at the Simply Blue Commander it shows the event Rx: Event: Link Established, Status: 00, BdAddr: 015814170008, Local Port: 01, Remote Port Number: 02 with status 00, which indicates the successful link establishment. In case this event reports status 0x03, the link establish-

See Figure 2-38 as example for the events sent for the Text test1234. The test is displayed in hex. Since the LMX9830/LMX9838 is still in command mode, meaning, it still is trying to interpret incoming UART data, it indicates incoming data on the Bluetooth link with the Incoming Data event on the UART. Figure 2-38. Incoming Data at LMX9830/LMX9838 in command mode 2.2.8 Send Data by using Send Data After actively establishing a link the LMX9830/LMX9838 will stay in command mode for either a second link or other configurations. Therefore any data to be sent to the other device have to be sent via the Send Data command. The command is formed out of the 6-byte header and the payload. The payload consists of Local RFCOMM Port (1 byte) The port, to which the package has to be sent to. The port defines the Bluetooth link the data have to be forwarded to. In this example the link has been established on port 01.

This means, incoming data will not be parsed to be a valid command, instead, all incoming data will be sent to the remote device directly. Transparent Mode on the local port 1 can be reached by sending the prepared command in the Command Directory. Figure 2-41. Switch to Transparent Mode on the UART Afterwards, all data will be sent directly to the other side. This can be simulated by sending Send Data: Test, LocalPort=01 again.
