H BLUETOOTH
®
MODULE
The IDRONAUT Wireless Module allows bidirectional full duplex communications between the
OCEAN SEVEN 310 probes and a personal computer (Desktop, Laptop) or PDA devices equipped with
a Bluetooth
®
device. The IDRONAUT Wireless Module is formed by a Bluetooth
®
OEM module
mounted inside the OCEAN SEVEN 310 probe housing and is designed to provide an interface
conforming to the Bluetooth
®
v1.1 class 1.
The operating range of the adapter is specified in 100m although line of sight ranges of 300m can be
achieved. However, if a class-2 Bluetooth
®
device is used to communicate with the IDRONAUT Wireless
Module, then the range will be limited to 10-20m as foreseen by class-2 devices.
The IDRONAUT Wireless Module allows instant wireless connectivity to any device supporting a
compatible Bluetooth
®
SPP protocol. The connection with the OCEAN SEVEN 310s probe among the
Bluetooth
®
devices registered on the network is guaranteed by means of the unique 8-digit PIN code
which identifies each IDRONAUT OCEAN SEVEN 310 probe.
Features:
❖ Fully Bluetooth
®
Class 1 v1.1, SPP compliant.
❖ Wireless range of over 100m (330ft).
❖ Platform independent.
❖ Access security guaranteed by means of a unique 8-digit PIN code.
❖ Low power sleep mode when not in use.
❖ Integrated antenna.
❖ Power supply: powered by the probe.
IDRONAUT Windows programs like REDAS-5 and ITERM flawlessly operate the OCEAN SEVEN 310
through the Wireless Module as if it were connected through an RS232 cable.
H.1 HOW IT WORKS
The OCEAN SEVEN 310 Wireless Module is always powered (low power stand-by) and is ready to
accept wireless connections once the probe is in ON condition. Communications through the OCEAN
SEVEN 310 Bluetooth
®
Wireless Module can be only achieved after a valid Bluetooth session is
established. Whenever the communication session is established, the probe automatically and
autonomously switches the communications from the wired interface: RS232C/RS422 or Telemetry to
the Wireless Module. Afterwards, communication continues using the wireless module until the
communication session drops or the OCEAN SEVEN 310 probe is switched off.
The only limitation is that the probe cannot be used with both interfaces (wire and wireless) at the same
time.
Automatic switch-off during deployment
Once the Ocean Seven 310 is deployed with the Bluetooth module active an automatic probe function
take control of the Bluetooth module. As consequence the Bluetooth module is automatically switched-
off when the probe is immersed in water.
The conductivity and pressure sensors are used to detect the condition. Two pre-configured thresholds
are checked during the data acquisition and if both of them are overpassed the Bluetooth module is
disabled saving probe battery energy.
