3.1 Automatic connection establishment
Automatic connection establishment is available in the following modes:
• An automatic connection will be initiated when control line DTR is on.
• An automatic connection will be initiated when transmit data is received from the
DTE device. All data received before the Bluetooth connection is established will
be buffered inside the BlueRS+C2 and automatically sent via the Bluetooth link.
• An Automatic connection will be initiated independent of any status line –
automatically after power up and initialization.
• No connection establishment initiated by this module. Bluetooth connection
requests from other Bluetooth devices will be automatically accepted (if
compatible).
To enable automatic call you have to set BlueRS+C2Configuration parameter "cmds"
to 6, 7, 8 or 13 (see below).
An established connection will be indicated by a status line (default: DCD). See also
configuration commands "cdcd" and "cdtr".
If a connection cannot be established successfully an automatic retry will be started.
The duration of trying to establish the connection and the pause for next retry can be
configured.
The Bluetooth device to be accessed is taken from the parameter "brad", it has to be
set up to the Bluetooth device address of the remote Bluetooth device. Additionally
the server channel has to be set up if not fitting to the default (1), see parameter
brsch.
