Master. PDC has to know the BD address of a target device as
well as sets a PIN code. PDC will send out the paring request to
the target device. The target device has to reply by the correct PIN
code set by PDC in order to establish a successful pairing
connection.
The PDC will show a successful pairing status after receiving
positive response from the target device, or a failed connection
with negative response. Otherwise, a timeout status will be shown
as if PDC has been waiting too long.
1.5.5. Pairing PDC as SPP Slave:
When PDC is powered on and Bluetooth® is activated, PDC is
ready for pairing process as a SPP Slave device. A PIN code has
to be set in PDC. At pairing process, the host device shall enter
the right PIN code to make a successful pairing.
1.5.6. Connect/disconnect with target devices:
The Master device decides to connect/disconnect with target
devices.
1.5.7. Reliable RF communication:
During transmission, each data is featured with protocol coding.
Transmission response would be made once data is received,
ACK or NAK. ACK indicates “acknowledged”, data is received and
decoded. NAK is meant “non-acknowledged” data is received but
cannot be recognized. Also use a STX/ETX packed and/or data
checksum is helped for verify if data is valid at receive host.
