5 - 22 DS2278 Digital Scanner Product Reference Guide
Auto-Reconnect Feature
When in SPP Master, Bluetooth Keyboard Emulation or when connected to the cradle (Cradle Host Mode), the
digital scanner automatically tries to reconnect to a remote device when a disconnection occurs that is due to the
radio losing communication. This can happen if the digital scanner goes out of range with the remote device, or if
the remote device powers down. The digital scanner tries to reconnect for the period of time specified by the
Reconnect Attempt Interval setting. During that time the green LED continues to blink.
If the auto-reconnect process fails due to page timeouts, the digital scanner sounds a page timeout beep (long
low/long high) and enters low power mode. The auto-reconnect process can be re-started by pulling the digital
scanner trigger.
If the auto-reconnect process fails because the remote device rejects the connection attempt, the digital scanner
sounds a connection reject beep sequence (see Wireless Beeper Definitions on page 5-4) and deletes the remote
pairing address. If this happens, a pairing bar code must be scanned to attempt a new connection to the remote
device.
The digital scanner has memory available for storing a remote Bluetooth address for each Master Mode (SPP,
Cradle). When switching between these modes, the digital scanner automatically tries to reconnect to the last
device it was connected to in that mode.

When a digital scanner disconnects as it goes out of range, it immediately attempts to reconnect. While the digital
scanner attempts to reconnect, the green LED continues to blink. If the auto-reconnect process fails, the digital
scanner emits a page timeout beep (long low/long high) and stops blinking the LED. The process can be restarted
by pulling the trigger.
The Beep on Reconnect Attempt feature is disabled by default. When enabled, the digital scanner emits 5 short
high beeps every 5 seconds while the re-connection attempt is in progress. Scan a bar code below to enable or
disable Beep on Reconnect Attempt.
NOTE If a bar code is scanned while the auto-reconnect sequence is in process, a transmission error beep sequence
sounds and the data is not transmitted to the host. After a connection is reestablished, normal scanning
operation returns. For error beep sequence definitions, see Beeper and LED Indications on page 2-1.
NOTE Switching between Bluetooth host types by scanning a host type bar code (page 5-4) causes the radio to be
reset. Scanning is disabled during this time. It takes several seconds for the digital scanner to re-initialize the
radio at which time scanning is enabled.
