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.
NOTE
RTS/CTS handshaking should be set by the Bluetooth
®
COM
driver for correct serial communication. If not used, the RTS
line must be forced to the level that doesn't block such
communication.
