1. Introduction Brainboxes BL-521 RS232 Bluetooth Adapter is a fully embedded, stand-alone Bluetooth solution, which will Bluetooth enable any device with an RS232 port. BL-521 does not require any host Bluetooth software. BL-521, when used in combination with another Bluetooth product, (e.g. Brainboxes USB adapter connected to a PC) replaces a cable freeing the device from the limits imposed by the cable specification.
If you are running HyperTerminal for the first time you will be prompted for information about your location. This section must be filled in, but will not affect the connection. In the next screen give a name to your connection (e.g. BL-521 Configuration), then click OK and select the Port that the BL-521 is plugged into. All other fields will then be greyed out. Click OK Select the communications parameters that your device is configured to. In this example we have used the factory defaults.
HyperTerminal should now be running. Now hit the “Enter” key once. This will activate the main menu as shown in 2.3.1 below. You will now be able to now interact with the menus as described in the following sections. 2.3. Changing specific settings. All Settings on the BL-521 are modified through the configuration menu. The main menu is shown below. 2.3.1. Main Menu 2.3.2. Setting the Communications Parameters This covers options 1 from the main menu, and displays a Communications submenu as shown below.
2.3.3. Changing Baud rate. After selecting option 1 from the “modify COMM menu”, the following baud rate menu is displayed. Selecting 0 immediately returns you to the previous menu; selecting any other option will store the appropriate configuration selection. If you power down your BL-521 at this point, the configuration changes will be discarded. Note: Configuration changes made in this menu will ONLY be applied when you select option 4 (Apply COMM settings) on the previous menu. 2.3.4. Changing parity.
Configuration changes made in this menu will ONLY be applied when option 4 from the previous menu is selected. 2.3.5. Changing data bits. Unfortunately this setting cannot be changed. Only the 8 data bit format is supported. 2.3.6. Changing number of stop bits. After selecting option 4 from the main menu, the following menu is displayed. Selecting 0 immediately returns you to the previous menu without storing any changes; selecting any other option will store the appropriate configuration selection.
4.2 Physically connecting your device to BL-521 via the RS232 connector Pinouts for standard cable Pinouts for supplied gender changer The female connector is designed so that it can be plugged directly into a PC’s standard COM port. The Female to Male “Gender Changer” allows maximum cabling flexibility where existing cabling is already attached. If you are connecting it directly to a different device you may need an additional cable, such as a “cross-over” or “null-modem” cable.
3.2.1. Discover the device This is performed in Brainboxes Windows software by first opening the “My Bluetooth Devices” window and clicking the discovery button. This sets the software to display all the Bluetooth devices it can find “in range”. Assuming that your BL-521 is switched on and in range you should see it displayed (perhaps alongside other Bluetooth devices in range) in the main screen. 3.2.2. Secure the relationship This is where you must “Bond” or “Pair” with the device.
You will then be prompted to enter a PIN number. Enter the Pin number (which is 00000000 – 8 zeros, unless you have configured it to be different. Click OK The Icon of your BL-521 in the main window should now change to indicate a “bonded” status as shown below. 3.2.3. Connect to the profile In order to actually connect to the appropriate function on the BL-521 you will need to discover it’s services. Simply Double-Click the device.
This “COM” port is now available for any application to use to communicate with your device, or in our case, the oscilloscope. 3.2.4. Connect your application to the COM port In our initial testing at our labs, we used the HyperTerminal application included in Windows to open COM25. Setting HyperTerminal to save data to a file called screen.bmp, and activating the hardcopy feature of the oscilloscope, caused all data to be sent from the scope to the file as listed.
