Auto-Reconnect Feature
When in SPP Master, Cradle Host Mode, and Bluetooth Keyboard Emulation, 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 time-outs, 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
pressing 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 <bl_blue><em_Emphasis>Wireless Beeper
Definitions on page 9-46) and deletes the remote pairing address. If this happens, a pairing barcode 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.
If a barcode 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 ???.
note Switching between Bluetooth host types by scanning a host type barcode
(<em_Emphasis><bl_blue>page 9-46) 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.
