Chapter 8 Communication
8.1 Bluetooth
Interface
The QR-coded parameter menu and the configuration software (ScannerSetting_2D) provide a choice of various
communications conditions. Under the communications conditions you choose, code data read can be transferred to
the external equipment or computer.
(1) Communications protocol
When the scanner is in SPP profile, you can select either non-acknowledge mode, ACK/NAK mode, or data
packaging mode.
Non-acknowledge mode (default)
The scanner transfers code data read, regardless of the CTS signal level.
ACK/NAK mode
The scanner transfers 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_2D) only provides ACK/NAK timeout
settings from 100 ms to 9.9 s in 100 ms increments.
ACK: Normal end
NAK: Retransfer
Data packaging mode
- To host
The scanner wraps the code data in a packet with a CRC for transfer to a commercially available Bluetooth
device or
other equipment. For further details, see Section 8.4.
(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
wireless link has been broken.
