GRYPHON™ BT OPERATION
3.2.3
Sleep State
The µP in the reader enters a "Sleep" state after 5 minutes of no reading for
minimum power consumption.
3.2.4
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
for correct serial communication. If not used, the RTS line must be
forced to the level that doesn't block such communication, otherwise,
after 1 minute Gryphon™ BT interrupts the radio link (disconnects).
