When in SPP Central, Cradle Host mode, or for Bluetooth Keyboard Emulation, the scanner automatically tries to reconnect to a remote device when it disconnects due to losing radio communication.
This occurs if the scanner moves out of range of the remote device, or if the remote device powers down. The scanner tries to reconnect for the period of time specified by the Reconnect Attempt Interval setting. During that time the green LED blinks.
If auto-reconnect fails due to page timeouts, the scanner lights the red LED, the scanner sounds a page timeout beep (long low/long high), and enters low power mode. To restart the auto-reconnect process, pull the scanner trigger.
If auto-reconnect fails because the remote device rejects the connection attempt, the scanner sounds a connection reject beep sequence (see Wireless Beeper Definitions) and deletes the remote pairing address. Scan a pairing barcode to attempt a new connection to the remote device.
If you scan a barcode during the auto-reconnect sequence, a transmission error beep sequence sounds and the data does not transmit to the host. After re-connection, normal scanning operation returns. For error beep sequence definitions, see Wireless Beeper Definitions.
The scanner has memory available for storing a remote Bluetooth address for each Central mode (SPP, Cradle). When switching between modes, the scanner automatically tries to reconnect to the last connected device in that mode.
Scanning a Radio Communications Host Type to select another Bluetooth host resets the radio which disables scanning. It takes several seconds for the scanner to re-initialize the radio and enable scanning.
