Auto-reconnect Feature
When in SPP Master or Cradle Host mode, the device 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 device goes out of
range with the remote device, or if the remote device powers down. The device 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 device 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 device trigger.

If the auto-reconnect process fails because the remote device rejects the connection attempt, the device sounds a
connection reject beep sequence (see
connection reject beep sequence (see
) 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 device has memory available for storing a remote Bluetooth address for each Master mode (SPP, Cradle).
When switching between these modes, the device automatically tries to reconnect to the last device it was
connected to in that mode.

Reconnect Attempt Beep Feedback
When a device disconnects as it goes out of range, it immediately attempts to reconnect. While the device attempts
to reconnect, the green LED continues to blink. If the auto-reconnect process fails, the device 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 device emits 5 short high beeps
every 5 seconds while the reconnect attempt is in progress.

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

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 device to re-initialize the
radio at which time scanning is enabled.
