Bluetooth For Industry
• Brainboxes - Who We Are.
• Bluetooth In Industrial, Scientific & Medical Markets.
• Bluetooth As A Simple Cable Replacement:- The
Issues To Overcome.
• Bluetooth In Real Roll Outs, Right Now.
• Conclusion.
Bluetooth: The Vision
• At conferences like this, we have seen
Bluetooth portrayed as giving us always on
high speed internet connectivity as we walk,
ride or fly.
• The reality of today is that the basic
Bluetooth technology works but it takes effort
& knowledge to make it work well.
• Bluetooth is not yet ready for the low cost
consumer market, where technical support is
on an individual case basis and is expensive.
Industrial applications
• ISM band -Industrial, Scientific and
Medical users are different to mass
market consumers.
• ISM users are technically savvy
people who are used to working
complicated equipment.
• They need Bluetooth’s wireless
capability.
• One time technical support results in
many sales
• ISM users can & will pay a price that
reflects perceived value
Industrial applications.
• Many quantities in the ISM field are
already measured using devices that
provide an RS232 serial output.
• The connection and the data rate
are an ideal match for Bluetooth
making Bluetooth an instant cable
replacement solution.
Simple Cable Replacement
• The Simple Cable we are replacing is usually the
RS232 Serial Cable- some times RS422/485 cables.
• ISM users usually need a simple instant serial cable
replacement.
• RS232 cables are everywhere in industry:– Point of Sale Applications
– Credit Card reading
– Till Receipt Printing
– Bar code reading
– Medical Monitoring
– Data Collection
– Process Monitoring
– Process Control
ISM Users
• Bluetooth is a ideal for ISM users because:• They have technical know how.
• The things they measure are a good fit for
Bluetooth data rate, etc.
• They usually buy in volume.
• They have problems where radio is the
solution.
• They will spend money to solve their problems
The Issues
• Brainboxes - Who We Are.
• Bluetooth In Industrial, Scientific & Medical Markets.
• Bluetooth As A Simple Cable Replacement:The Issues To Overcome.
• Bluetooth In Real Roll Outs, Right Now.
• Conclusion.
The Ideal
• Instant Serial Cable Replacement.
• Ideally a pair of two preconfigured Bluetooth devices
running the Serial Port Profile can just be used to
replace a length of cable.
• However things are not as easy as they seem.
Lessons Learnt
• Communications parameters become an issue
• Unless the Bluetooth device can auto baud, that is
automatically detect and match baud rate, parity
and stop bits then not only do you need some
configuration utility but if the communications
parameters change whilst application is running
then disaster strikes.
• This is not a problem with cables.
Issues
• Power Issues:• Bluetooth devices need power.
• Either be mains power or battery power.
• Is there a power outlet convenient for each Bluetooth
device?
• If not then battery power may be the only option.
• Typically cables do not need power to work.
Issues
• Battery Issues:• Battery life- power down when not connected to save
battery power.
• Battery life- quick auto connect on power up.
• Battery life- a slow trickle charge is preferable having
to manually replace dead battery.
• Battery: When the battery is dead what happens to
Bluetooth settings?
• Typically a cable does not require battery power
Issues
• If the devices are not preconfigured to “just work”
with each other then other issues arise that do not
occur with cables:• Need:– to be able to make device discoverable
– to be able to search for other devices
– a pairing mechanism
– to be able to set security features
• All these issues mean we need a USER INTERFACE to
configure devices.
• Typically a cable does not need a user interface
Issues
• If there are several Bluetooth bar code scanners
how do you know which one you have found and
have paired with?
• Need visual or audio indication on devices when
connection made.
• Led to indicate when device is “Paired”
• Led indicates when device is “Connected”
• Or paired device beeps when connection made.
• Need a User interface to show device status
• Typically a cable does not need this
Biggest Issues
• These are just some of the issues of replacing a
cable.
• Plus there are all the technical issues of designing in
a Bluetooth radio.
Far too difficult unless you are an RF expert.
• The resources to develop the Bluetooth software
• High accreditation fees of Bluetooth approvals.
Far too expensive unless your volumes are huge.
• The issues seem formidably high.
Issues
• Fortunately help is at hand
• Brainboxes have tackled and resolved all these
issues.
• Allowing the wider community, who are not, and
who never will be, Bluetooth experts, a turn key
entrance to instant cable replacement.
• All of a sudden the considerable benefits of a
Bluetooth solution, mobility, safety, convenience,
ruggedness, simplicity are available in a $200 “it
just works” pack.

several form factors.
• An external add on
• With a cable when antenna placement is an
issue.

embedding Bluetooth inside devices.
• All are self contained requiring no external
software drivers
