Chapter 9 Communication

®
9.1 Bluetooth
Interface
The QR-coded parameter menu and the configuration software (Scan Tune App) provide a choice of various communications
conditions. Under the communications conditions you choose, scan code data can be transferred to the external equipment or
computer.
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 a broken Bluetooth

9.2 SPP Profile

The scanner supports the Serial Port Profile (SPP) that enables connecting to an Android, PC or other device equipped with a
®
Bluetooth
module that is compatible with Bluetooth
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 read code data.
ACK/NAK mode
The scanner transfers read code data. After that, however, it waits for the response from the host and processes it. The
configuration software (Scan Tune App) 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
other device. For further details, see Section 9.5.
