750-644 Bluetooth RF-Transceiver
• The MAC ID of the device to be connected is entered for one of the ad-hoc
slots (0x10 ... 0x15).
• The slot has been enabled for the connection.
The connection is not established automatically in this operating mode, i.e. if the
local 750-644 I/O module should establish a connection, the process must be
initiated by a corresponding parameter in the process image (see section "Process
Image"). In this operating mode, connections can also be established externally. If
the above conditions are met, the 750-644 I/O module automatically accepts a
connection established externally.

Operation as a Slave in "Ad-hoc Communication" Mode

When operated as a slave in "Ad-hoc Communication" mode, the 750-644 I/O
module can be connected to other Bluetooth
they assume the role of a master or slave.
The number of supported connections, the requirements for the configuration and
the procedures for establishing a connection are identical when operated as a
master.
Lower power when operating in a scatternet!
If the 750-644 I/O module is operated as a slave in "Ad-hoc Communication"
mode and it maintains more than one connection, the resulting Bluetooth
network may not have a piconet topology, but a scatternet topology. If so,
significantly worse timing must be expected.

Visibility and Connectivity

Whether the 750-644 I/O module responds to a device scan of remote Bluetooth
devices or not depends on the set operating mode. If yes, it is "visible".
The 750-644 I/O module is visible under the following conditions:
• "Ad-hoc Communication" mode or
• "Configuration" mode
A connection between the 750-644 I/O module and a remote Bluetooth
generally only possible if the configuration of the I/O module defines it as an
authorized device.
• "Real-Time Communication" mode:
The MAC ID of the remote device is entered for one of the slot addresses
0x20 ... 0x26. The related slot is activated for the connection.
• "Ad-hoc Communication" mode:
The MAC ID of the remote device is entered for one of the slot addresses
0x10 ... 0x15. The related slot is activated for the connection.
