radio activity, and thus lower power consumption. These parameters are the number of
connection attempts and the connection period. These parameters control how often and
how many connection attempts are to be performed. See the client command more
information ( AT+BTCLT ).
In addition to the ability to support Automatic Connection Mode, the device can be
configured to use different Bluetooth security modes. These modes are no security,
authentication (pairing) required, and encryption required. No security means that the
1SPP firmware will not force any security procedures during connection. Authentication
required means that the 1SPP firmware will force Bluetooth authentication when a
connection is either accepted or made. Bluetooth authentication requires the use of
Bluetooth PIN codes and/or Bluetooth link keys. The final security mode, encryption, is a
superset of authentication. This mode encrypts all data that is sent over the Bluetooth
connection. Encryption requires a Bluetooth link key that is generated during
authentication. Therefore, encryption can be thought of as a superset of authentication
since authentication must be performed prior to the actual encryption.
While in Data Mode, the 1SPP firmware supports the ability to map the state of the RS-
232 input signals; RI, CD, DTR, and DSR, over the Bluetooth link. Likewise, the output
RS-232 signals will be mapped to the signal state that is being reported by the remote
device. This functionality is not the default functionality. By default, DTR and DSR will
be used for local flow information (similar to how a modem behaves). When the signals
are not mapped across the Bluetooth connection, the CD signal, if it is an output, will
reflect the Bluetooth connection state (asserted if there is a connection). If the CD signal
is an input signal, then it will be ignored. In this mode, the RI signal is mapped directly
through.
The configuration of input and output RS-232 signals depends on whether the device is
configured as a DTE or DCE device and can be seen in the following tables. The
RTS/CTS lines are never mapped over the Bluetooth connection and are only used for
flow control between the host processor and the BGB203 device. Note that the device
does not have to be configured to use all of the signals discussed in this section.
