Bluetooth
Network Topology
Each Bluetooth device has a 48-bit unique address
(281 trillion)
Bluetooth devices have two operation modes:
-
Master or Slave
-
Master determines which of the 79 available
radio channels will be used in what sequence (the
frequency hopping sequence - 1600hops/sec)
-
Slaves synchronize themselves to Master's
hopping sequence and uses its clock and address

RS-232 is a widely used standard for communications
between industrial, medical and scientific apparatus.
Despite growth in alternatives such as Ethernet and USB,
RS-232 remains the only communications standard which
can offer the widespread interoperability and cost effectiveness
required by manufacturers of this equipment. However the
need for a physical, wired connection between devices
can be inconvenient. Therefore, BlueRadiosBluetooth RS-232 "wireless wire" is provided
as a convenient solution.
