AWR300 User Manual
Choose a device from the list and select it by pressing
the Bluetooth partner and will try to connect to it automatically and permanently, if the reader is
configured to Master Mode.
Usually there should not be too many Bluetooth devices in use with the AWR300. In order to
prevent unnecessary scans when switching from one Bluetooth partner to another one, the reader
stores a 'Bluetooth Device History'. This list includes the devices, which were selected as
Bluetooth partner in the past. So scanning for already known devices is not required.
The AWR300 supports four different Bluetooth profiles: Serial Port Profile (SPP), Human Interface
Device (HID) and Bluetooth Low Energy (BLE), where BLE is more or less another technology
rather than a profile.
SPP emulates a serial cable to provide a simple replacement for RS232 connections. Commands
can be sent into both directions – it uses virtual serial ports.
HID is used for 'typing in' the EID sent via Bluetooth into text fields of applications running on the
host device. This removes the need to develop a serial interface for the reader. The AWL200 is
connected to the host as a 'virtual keyboard'. When the cursor is in a text field in the app running
on the host, the EID is filled into this field after a transponder has been read. Please note that it
is not possible to send commands to the AWL200 in HID mode – communication only works into
one direction here.
HID smart: Same as HID but the connection to the other device is only established after a
transponder has been read. This is required for the use with Apple devices because as long as a
Bluetooth device is connected as HID keyboard, the on-screen keyboard will not be available at
all.
BLE is reserved for special applications at the moment.

The discovered devices are listed after the scan, sorted
according to their names.
Sometimes it might be useful to see the BD-address of the
found devices instead of the names. You may switch
between both views by using the
Now you can see the list of discovered devices with their
BD-addresses instead of the device names. Very often, the
BD-address is somewhere on a label of a Bluetooth device.
Since this address is unique, it can help to identify the
correct device quickly.
