Gryphon™ BT as Master
A Gryphon™ BT is Master when the remote Bluetooth
®
with a Bluetooth
barcode printer. Once set as Master, a Gryphon™ BT reader
must be configured to recognize the address of the Slave device to which it
wants to communicate.
By default, at startup the reader initializes the communication with the Slave. If
the connection is successful, the reader can send barcodes to the Slave
device.
If the connection is not successful, you can attempt a connection manually by
double-clicking the reader trigger. Radio connections can also be managed
manually as described in the Gryphon™ BT Reference Manual on the
configuration CD-ROM.
SLEEP STATE
The µP in the reader enters a "Sleep" state after 5 minutes of no reading for
minimum power consumption.
DATA TRANSMISSION
The transmission of data can be transparent (no ACK/NACK protocol), when
each character is read and immediately sent to the Host (default value).
Otherwise, data transmission can be with flow control (with ACK/NACK
protocol), when, after each reading, Gryphon™ BT waits for an acknowledge
that the remote Host received the data before reading and sending the
following code.
RTS/CTS handshaking should be set by the Bluetooth
driver for correct serial communication. If not used, the RTS
line must be forced to the level that doesn't block such
communication.
