How Bluetooth Advertising Works
Bloozy operates using the internationally recognized and accepted Bluetooth™
data networking system.
The equipment operates in the Industrial, Medical and Scientific (IMS) radio
transfer band at approx 2.45 Ghz and has been globally ratified for safe, interference
The Bloozy units operate with a Class 1 Bluetooth device which gives a theoretical
range of 100m in free space.
When the Bloozy unit detects a Bluetooth enabled device in range, the details
of the device such as the unique ID (MAC Address), user name of the device is
logged into the database along with the date and time of the discovery.
Providing the discovered device satisfies the transmission criteria1,
Bloozy will then attempt to deliver the Bloozy message to the device.
If the attempt is successful then Bloozy will register that the device successfully
received the file and will then stop any further attempts of sending to the
device for the Resend
Elapsed Time Period2.
Should the device not accept the Bloozy message then the unit will continue
to attempt to send to the device until the Maximum
Attempts3 has been met with
a Retry Delay4
between each attempt being set by the operator.
These are the parameters that are set up by the system to determine whether
or not the detected unit should have a transmission attempt made. They include:
OBEX Capable: Whether or not the unit is capable of receiving a OBEX
White-listed: If the owner of a device registers that they do not wish
ever to be included by a Bloozy system a database of these devices will disallow
the Bloozy unit to ever attempt to send to them.
Recently Received: If the device has only recently received a Bloozy
message from this box
Elapsed Time Period
The time period between possible attempts to send to a device again. This period
has a minimum period of 6 hours and a maximum of 48 hours. This is primarily
to stop the incessant sending of files to devices that have already been detected
3. Maximum Attempts
The maximum number of attempts after discovery of a device that the Bloozy unit
will attempt to deliver the message, configurable to give the best chance of
4. Retry Delay
The delay between attempts to deliver the message, configurable to give the
best chance of message delivery.
