10.1 Bluetooth Interface
The bar-coded parameter menu and the configuration software (ScannerSetting) provide a choice of various
communications conditions. Under the communications conditions you choose, bar code data read can be transferred
to the external equipment or computer.
(1) Communications protocol
You can select either "Non-acknowledge mode," "ACK/NAK mode," or "Data packaging mode (to host or
BA10-RKU)."
Non-acknowledge mode (default)
The scanner transfers bar code data read, regardless of the CTS signal level.
ACK/NAK mode
The scanner transfers bar code data read, regardless of the CTS signal level. After that, however, it waits for the
response from the host and processes it. The configuration software (ScannerSetting) provides ACK/NAK timeout
settings from 1 to 25 seconds in one-second increments. Models that do not support data packaging (packetizing)
provide ACK/NAK timeout settings from 100 ms to 9.9 seconds in 100 ms increments.
ACK: Normal end
NAK: Retransfer
Data packaging mode
- To BA10-RKU
The scanner wraps the bar code data in a packet with a CRC for transfer to the Bluetooth
see Section 10.3.
- To host
The scanner wraps the bar code data in a packet with a CRC for transfer to a commercially available Bluetooth
device or other equipment. For further details, see Section 10.3.
(2) Timeout period for slave to wait for a connection request
The scanner, as a slave, waits for a connection request from the master for the specified timeout period--2 (default), 4,
10, or 30 minutes.
If the scanner cannot receive a connection request from the master within the specified timeout period, it switches to
standby, the same status as the Bluetooth
(3) Automatic disconnection
®
If the Bluetooth interface is not used for the specified timeout period, the scanner automatically breaks the
®
Bluetooth wireless link.
You can select the timeout period within the range from 5 to 640 minutes in 5-minute increments and also disable the
automatic disconnection, using the configuration software (ScannerSetting).
(4) Clearing data after Bluetooth
A setting specifies whether the scanner clears transfer data if the Bluetooth
other during a data transfer. Specifying no, the default setting, transmits any data remaining in the transfer buffer once
®
the Bluetooth wireless link is re-established. Note, however, that, regardless of this and other operation settings for
®
Bluetooth wireless link breaks, transfer data lost in transit is not resent.
(5) Pairing
The scanner does not normally require pairing, but supports it if the target device so requires. Pairing involves sharing
a PIN code. For further details, see Appendix 4.
