for details.
10.1 Bluetooth
®
Charging Station Interface
The CRA-A271 and CRA-A274 connect to a host via a USB cable. It automatically detects the USB hosts
and connects as a HID keyboard device by default. To change to another interface type, scan the desired
interface configuration code or use CortexTools3.
10.2 Bluetooth Auto-Reconnect
If a CR2700 reader is connected directly to a host via BLE, it communicates as a Bluetooth HID
keyboard device.

9.1 Bluetooth Radio Power
The CR2700 readers use Class 2 Bluetooth Radio. Its power output level in the reader is set to 0 dbm by
default but can be configured to lower or higher maximum levels. The default power output level of the
Bluetooth radio on the CRA-A271 charger and CRA-BTDG27 Bluetooth Dongle is -8 dbm and also can be
adjusted. Reducing radio power output will restrict data transmission range. Refer to CCD for commands
to change radio power level or contact Code Support.
9.2 Bluetooth Auto-Reconnect
The CR2700 attempts to reconnect automatically when a connection is lost (for example, when the reader
is moved out of range, loss of battery power, rebooting, or Bluetooth charging station or host powering
down). This auto-reconnect feature is enabled by default but can be disabled. Default time out for auto-
reconnect attempt is 5 minutes but can be configured for different durations.
9.3 Bluetooth Security
By default, BLE communication in the CR2700 is AES-128 encrypted. For enhanced security requirements,
please contact Code Support.
