Zebra DS6878 Product Reference Guide

Radio Communications 4 - 17
Auto-reconnect Feature
When in SPP Master or 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 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 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 4-3) 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.
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 Definitions on page 2-1.
NOTE Switching between Bluetooth host types by scanning a host type bar code ( page 4-4) 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.
