Auto-reconnect Feature

When in SPP Master or Cradle Host mode, the linear imager 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 linear imager scanner goes out of range with the remote device, or if the remote device powers down. The
linear imager 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 linear imager 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 linear imager scanner trigger.
If the auto-reconnect process fails because the remote device rejects the connection attempt, the linear imager
scanner sounds a connection reject beep sequence (see
the remote pairing address. If this happens, a pairing bar code must be scanned to attempt a new connection
to the remote device.
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
2-1.
The linear imager scanner has memory available for storing a remote Bluetooth address for each Master mode
(SPP, Cradle). When switching between these modes, the linear imager scanner automatically tries to
reconnect to the last device it was connected to in that mode.
NOTE Switching between Bluetooth host types by scanning a host type bar code
be reset. Scanning is disabled during this time. It takes several seconds for the linear imager scanner to
re-initialize the radio at which time scanning is enabled.
