5.5 RADIO PARAMETERS – LYNX™ BT WITH BT DEVICE
5.5.1
ACK/NACK Protocol with BT Device
The transmission protocol takes place between the reader and the Host. The reader
passes its data (code read) to the remote Bluetooth
®
device (Host).
In the following descriptions the completed transmission is indicated by the Beeper
Control for Radio Response parameter with its default setting to "Good Decode and
Good Reception" beep, see par. 5.6.2.
When ACK/NACK is disabled, there is no control from reader to Host transmission,
therefore the reader responds with the good reception tone.

ACK/NACK Enabled
When ACK/NACK is enabled, the Host sends an ACK character (06 HEX) in the case
of good reception or the NACK character (15 HEX) requesting re-transmission, in the
case of bad reception. Only after the ACK character is received by Lynx™ BT does
the reader respond with the good reception tone.
If the reader does not receive an ACK or NACK, transmission is ended after the
Radio Protocol Timeout, par. 5.6.
