It is not recommended to have too many Bluetooth devices connected to the AWR300. 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.

Choose a device from the history to change the Bluetooth
partner. The AWR300 then uses this device as remote
device until further changes.

The AWR300 supports four different Bluetooth profiles:
Serial Port 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.
iPOD Accessory Protocol Profile (iAP):
Allows serial communication with the iOS devices
Human Interface Device (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 AWR300 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 entered in this field after a
transponder has been read. Note that it is not possible to send commands to the AWR300 in
HID mode – communication only works into one direction.
HID smart
: This is the 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 if
a Bluetooth device is connected as HID keyboard, the on-screen keyboard is not available.
Bluetooth Low Energy (
BLE)
is currently reserved for special applications.

The AWR300 itself does not need a passkey. However, if other Bluetooth devices use a higher
security level and they require one, the passkeys on both devices must match to establish a
connection.
