The best way to connect a Bluetooth scanner

Scanners should connect differently than most of the Bluetooth devices you’re used to. Normally you’d go into Setup, Bluetooth, (or some variation of this) then find the device you want to connect and instruct the OS to make a connection to this device. This type of connection is an outgoing connection, i.e. it’s initiated by the computer.

Most operating systems will not maintain a reliable connection this way. You probably know this from personal experience. How many times do you have to reconnect your Bluetooth headset to your phone? This is inconvenient when using a phone; for a scanner user who is being paid to manage inventory this is lost time and money. Do you really want to tell a user to go into Control Panel every time he needs to reconnect?

A better way to connect is to use an outgoing connection. The scanner connects to the Bluetooth MAC address of the computer and spawns a virtual Com port connection. Intermec has been doing this for years with their vehicle mount computers. Here’s a barcode from the side of a CV31 vehicle mount computer:

This is very convenient for the user, scan the barcode and get connected. Even better, this is a much more reliable connection than on outgoing connection. I have an SF61 Bluetooth scanner in house that’s connected to a Dell tablet using an outgoing connection, and it’s been running for more than six months.

If you want to implement this on a non-Intermec laptop or tablet PC you’ll need to install Intermec’s Smart Wedge software. Once it’s installed it will generate a connection bar code on screen:

Scan the barcode and you’ll connect. You’ll hear three ascending beeps when the connection is established.

Under Tools, Options, select “Reduce Smart Wedge in System Tray” and “Start Smart Wedge with Windows” and you will have a reliable and robust connection established between your scanner and PC.

Note that the Smart Wedge software will take the incoming data from the barcode scanner and post it to the current cursor position in the application that has Windows’ focus, so you can use this with almost any software.

In the unlikely event that the scanner loses connection with Smart Wedge, jut scan the connection barcode again to reestablish it. Of course, this only works with Intermec scanners; the SF61, SG20, and SR61B will all work.
