1. Introduction SMART’s RS232 Bluetooth adapters are fully embedded, stand-alone Bluetooth solutions, which will Bluetooth enable any device with an RS232 port. The adapters do not require any additional Bluetooth software. For many applications, a Bluetooth adapter used in combination with another Bluetooth product (e.g.
4. Changing Settings This device contains a comprehensive set of Bluetooth and COM port features which can be changed from an easy to use “bulletin board” type configuration menu. This section gives full details about the changes that can be made, how to make them, and the implications the changes will have on the manner in which your adapter behaves. 4.1. Configuration features at a glance Below is a quick list of the configuration options that are available from the interactive menu.
5. Configuration Menu 5.1. Navigation As a general principle, from any menu screen hitting the “Enter” key refreshes the current menu and hitting 0 returns the user to the previous menu. Menu selection is performed by pressing the number on your keyboard that corresponds to the number listed on the menu item you wish to view/configure. Reminder: The configuration menu is not available while a radio (Bluetooth) connection is established. 5.2.
5.3. Communications Parameters Selecting option 1 from the “Main Menu” menu displays the Communications settings menu. It is from this menu that all available serial port settings can be changed. The available options are detailed below. ======================================== ============== MAIN MENU =============== =============== Version 3.
5.3.2.
5.3.3. Data bits Unfortunately this setting cannot be changed. The adapter only supports the 8 data bit format. Thus there is not a configuration menu option for this setting. 5.3.4. Parity ======================================== =========== Modify COMM Settings ========== ======================================== Selecting option 2 from the “Modify COMM Settings” menu enters the Set Parity menu.
5.3.6. Handshaking Handshaking is discussed in more detail in the section entitled “Handshaking Options” as it is not an option directly available from the menu. 5.3.7.
======================================== ========= Modify Bluetooth Settings =========== ======================================== Key [0] - MAIN MENU Key [1] - Set Discoverability Key [2] - Set Security Mode Key [3] - Set Encryption Key [4] - Set PIN Key [5] - Set Partner Device Key [6] - Set Client/Server Key [7] - Set Local Name Key [8] - Set Class of Device After selecting option “1” from the “Modify Bluetooth Settings” menu, the following menu is displayed.
Selecting option “2” will immediately place your ADAPTER into security mode 2. This mode allows remote Bluetooth devices to search for and retrieve the services on your ADAPTER, but will not allow them to connect unless the 2 devices are paired. Selecting option “3” will immediately place your ADAPTER into security mode 3. This is the highest security mode available. Connections of any kind from a remote Bluetooth device are only allowed after a successful “pairing” has been performed.
5.4.3. Encryption ======================================== ========= Modify Bluetooth Settings =========== ======================================== After selecting option 3 from the “Modify Bluetooth Settings” menu, the following menu is displayed.
======================================== ================ Set PIN ================= ======================================== Selecting option 4 from the “Set PIN” menu will display the following menu below.
5.4.5. Partner Device This feature serves 2 purposes. In Server mode it shows the address of the last device to successfully bond and connect. In Client mode, it shows the device to which the product will attempt to pair/connect. A remote device address must first be entered into the “partner device” section before the product, configured in Client mode, will be able to initiate any connections to that remote device.
======================================== ============ Set Partner Device ============== ======================================== This expiration only deletes the Link Key created during pairing and doesn’ t remove the device itself. Key [0] - PREVIOUS MENU Key [1] - Remove partner device Key [2] – Expire pairing Selecting the option to remove the partner device as below will remove both the link key created during the pair, and it will remove the partner device itself from the memory of ADAPTER.

5.8. Resetting ADAPTER The ADAPTER has a “reset button” located on the side of the case as shown in section 3.1 ADAPTER above. This button performs 2 different functions. a) Resets Paired Devices. A short press (less than 3 seconds) of the reset button causes any paired device information to be deleted.
With a DCE adapter or a DTE when a “gender changer/null-modem” is connected, the (Female 9 pin D Type) Pin-Outs are… Pin Signal 1 N/C 2 3 Pin Signal Pin Signal 4 DSR - N/C 7 CTS TxD 5 Ground 8 RTS RxD 6 DTR - N/C 9 Auto-detect Pwr The female connector is designed so that it can be plugged directly into a PC’s motherboard COM port. If you are connecting it directly to a different device you may need an additional cable, such as a “cross-over” or “nullmodem” cable.

7.2.3. Discover the device Using SMART’s Bluetooth Windows software (for controlling the USB adapter) by first opening the “Bluetooth Devices” window and clicking the Search for Devices icon. This sets the software to display all the Bluetooth devices it can find “in range”. This software will not operate the adapter products if attached to the PC. Assuming that your adapter is switched on and in radio range you should see it displayed (perhaps alongside other Bluetooth devices in range) in the main screen.
