WWS550i: How do I enable Bluetooth SPP on my WWS550i
scanner?
Internal User - 2017-06-22 - in WWS550i
If your PC application expects serial input, the WWS550i scanner can be set to use
Bluetooth SPP mode (Serial Port Protocol).
If you need to enable Bluetooth SPP (Serial Port Protocol) for your WWS550i, you can do it
by scanning barcodes from the scanner's Quick Start Guide or User Manual.
1. Factory Default
2. Bluetooth SPP (Bluetooth COM)
Start the pairing process in Windows.
Scanners with later firmware (1.04 and higher) will pair without a pairing code. For earlier
firmware models (1.03 and earlier), select the option to "Enter the device's pairing code"
and click Next, then enter 1234.
During the pairing process, Windows should give one or more notifications that will include
the numbered COM port (for example, COM3) that it is assigning to the scanner. If you need
to find or change this port number, this can be done through the Device Manager in
Windows.
Info & Troubleshooting
After pairing the scanner, when you open the COM port from the receiving
application, the scanner should beep twice.
If the scanner gives 3 beeps when scanning a barcode, this indicates there is no
application listening on the COM port the scanner is using.
During the scanner pairing process, if the listening application already has the COM
port open that the scanner gets assigned to, the scanner pairing process will seem to
work from Windows, but the scanner never actually sends data (it may give three
beeps). Remove the scanner from Windows, close the application, pair again, then
try the application again.
Wasp's Serial-to-Keyboard program is a simple program that can be installed and
used to test the serial connection. It accepts serial input, then sends it to the PC as if
typed by a keyboard. It has a one-line "Last Scan" display field (screenshot below),
and can be used in conjunction with a text editor such as Notepad to show scanned
barcode data. It can be downloaded here:

Some programs will have trouble receiving data if the serial settings don't match in
Device Manager and the receiving program. Here's an example of matching
settings:
If you still encounter problems with getting an SPP mode scanner communicating to
Windows, there are several registry settings that can be cleared. Remove the paired
scanner, clear the registry entries, then try the pairing process again.
1. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\COM Name Arbiter\ComDB
Delete any data in this field, as shown:
2. HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM
Delete any entries here. In the example below, you would delete \Device\Serial0 and
\Device\Serial1.
3. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Ports
Delete any entries starting with COM. In the example below, you would delete COM3
through COM6 (other entries in the list are different port types, so don't delete them).
Exception: If you know for sure that a specific port number is in use by something else on
your system, you can leave it alone.
