What is
• A proprietary open wireless technology standard for exchanging data (eg. voice,
music, video, etc.) over short distances between two paired devices
• The technology uses short wavelength radio waves
• Operates in the 2.4 – 2.483 GHz range
• This is within the unlicensed Industrial, Scientific and Medical (ISM) 2.4 GHz short-
range radio frequency band
• Uses adaptive frequency hopping to avoid interference
–
usually performs 1600 hops per second
• Short range transmission
History of Bluetooth
• In 1996, a group of technology companies came together to develop a unified standard for
cell phones and computers to communicate
• The original technology was invented in 1994 by engineers working at Ericsson
• When Bluetooth was officially introduced in 1998, its intended basic purpose was to be a
wire replacement technology in order to rapidly transfer voice and data
• It was named after a 10th century Danish king, Harald Blatand, or Harold Bluetooth in
English. He was famous for uniting warring factions of Sweden, Norway and Denmark
Bluetooth Applications Examples
•
Wireless control and communication between a cell phone and a wireless headset
•
Wireless communication between computers and input devices, such as keyboards,
printers and mice
•
Wireless replacement of serial port applications, such as GPS receivers and medical
devices (i.e. – NOAHLink)
•
Wireless networking of computers, where small amounts of information exchange
occur
•
Wireless transfer of contact information and calendar details
The difference between Bluetooth and other radio wave based
transmissions
• So, if Bluetooth, radio, TV, FM (Roger) systems, etc. all use radio waves, how are they
different?
Bluetooth
Radio, TV, FM (Roger) systems
 short distances
 longer distances
 one to one communication between  one device can broadcast to many
paired devices
devices
Bluetooth Versions
• There have been many versions of the standard and it is constantly evolving:
–
Version 1.0 - bad
–
Version 1.1 - better
–
Version 1.2 - usable (original RAZR used this)
–
Version 2.0 + EDR - passed in 2004 and finally allowed good headsets
–
Version 2.1 + EDR
–
Version 3.0 + HS & Low Energy
–
Version 4.0
–
Version 4.1
–
Version 4.2 – released December 2014
Bluetooth & Power Consumption
• Low power consumption was a design consideration from the beginning
• There are three classifications, cell phones are typically Class 2
–
Class 1
•
100mW maximum power consumption
•
300 foot range
– Class 2
•
2.5 mW maximum power consumption
•
30 foot range
– Class 3
•
1 mW maximum power consumption
•
3 foot range
How is Bluetooth different than the wireless link between hearing
aids or between hearing aids and the Phonak streamer?
• The frequency and mode of transmission
–
The wireless signal between 2 Phonak hearing aids and between the hearing aids
and the iCom/ComPilot is a 10.6MHz signal that is unique to Phonak
–
We call it HiBAN – hearing instrument body area network
–
It uses an induction loop type transmission
• So the transmission between a cell phone or TVLink and the Phonak streamer is a
Bluetooth signal, but the transmission from the streamer to the hearing aids is
Phonak’s 10.6MHz proprietary signal
–
So two wireless transmissions (Bluetooth and Phonak) are used to make the whole
process work!
Bluetooth Profiles
Not all Bluetooth signals are created equal!
• Think of profiles as capabilities or features
• Both devices have to support the same profile for the Bluetooth transmission to work
• There are many different profiles available
Available Bluetooth Profiles
• The variety of profiles includes:
–
Advanced Audio Distribution Profile (A2DP), Audio / Video Control Transport
Protocol (AVRCP), Basic Imaging Profile (BIP), Basic Printing Profile (BPP),
Common ISDN Access Profile (CIP), Cordless Telephony Profile (CTP), Dial-Up
Network Profile (DUN), Fax Profile (FAX), File Transfer Profile (FTP), General
Audio/Video Distribution Profile (GAVDP), Generic Object Profile (GOEP)
Hands-Free Profile (HFP), Hard Copy Cable Replacement Profile (HCRP),
Headset Profile (HSP), Human Interface Device Profile (HID), Intercom Profile
(ICP), Object Push Profile (OPP), Personal Area Networking Profile (PAN),
Service Discovery Application Profile (SDAP), Service Port Profile (SPP),
Synchronization Profile (SYNC), Video Distribution Profile (VDP)
Bluetooth Profiles
• So… depending on the data being transmitted, different profiles are necessary
• With regards to the Phonak streamers and other audio transmissions, the profiles
important are to you include:
–
Headset Profile (HSP)
–
Hands-Free Profile (HFP)
–
Advanced Audio Distribution Profile (A2DP)
Other profiles used are:
–
Audio Video Remote Control Profile (AVRCP)
–
Phone Book Access Profile (PBAP)
Bluetooth Profiles
Headset Profile (HSP)
– This is the most commonly used profile and allows mobile phones to communicate
with wireless headsets
– It only allows to ability to ring, adjust the volume, answer a call and hang up
Hands-Free Profile (HFP)
– This is commonly used to allow communication with a car hands free system
– The extra features that HFP allows are last number redial, call waiting and voice
dialing
Advanced Audio Distribution Profile (A2DP)
– This profile is used to define how high quality mono and stereo audio information is
streamed from one device to another (one way transmission)
– Examples include:
• Music from a mobile phone to a car audio system or a wireless headset
• Audio from a television or stereo to a wireless headset
Bluetooth Profiles
• Most Bluetooth headsets support both HSP and HFP profiles. This is why the ComPilot
can conflict with car Bluetooth systems!
–
Therefore, your client will have to decide which device (ie. ComPilot or the car) they
wish to listen to their phone through
• It is important to note that most smart phones (eg. iPhone, androids) use both a HSP/HFP
and A2DP Bluetooth profiles
• This way, the cell phone can transmit calls as well as audio such as music, videos and
games to the ComPilot
• ….keep this in mind for when we discuss how many devices can be active with the
ComPilot at one time and as we discuss troubleshooting these devices
Which devices can be monitored at the same time?
• The “Multi-Point” feature
The “Multi point” feature
• The iCom and ComPilot allow you to monitor:
–
2 channels A2DP and
–
2 channels HFP/HSP at the same time
• The ComPilot II and ComPilot Air II allow you to monitor:
–
3 channels of A2DP and
–
2 channels of HFP/HSP at the same time
• You can toggle between inputs using the main button of any of the streamers
• Keep in mind that most cell phones will transmit both speech (HFP/HSP) and music
(A2DP)
• Most Bluetooth landline cordless phones will only transmit via HSP/HFP
• A audio/music streamer (eg. TVLink, iPad) transmits via A2DP
Which devices can be supported in parallel?
Grouping & Pairing & Connecting… Oh My!
• There are three terms that are frequently interchanged, however, need to be clearly
defined
• Grouping occurs in the Phonak software. It is when an ComPilot is attached to
hearing instruments to create a hearing system.
• Pairing is when a trusted relationship is established between two Bluetooth devices.
The devices place each other on their “buddy list”
• Connecting is when two previously paired devices recognize each other and start
talking.
Bluetooth: Pairing
• Pairing occurs when two devices agree that it is safe to communicate with one another
• To pair two compatible devices, a shared pin code is needed
• Many devices use the standard 0000, especially those without keyboards for manual
number input
• Once two devices are paired, they do not need to be re-paired unless either device is
reset or the pairing has been deleted
"we're friends now, it's safe to talk to you"
Bluetooth: Pairing
•
The pairing process is:
1.
Device A searches for other Bluetooth devices
2.
Device B is found by Device A
3.
Device A asks for a pin code and sends it to Device B
4.
Device B sends the pin code back to Device A and creates a trusted pairing if
both pin codes are the same
Connecting
• In the phone’s Bluetooth menu, find the list of paired devices
• Choose “Phonak_____” and select “Connect”
• Often there is some visual confirmation on the phone that it is currently connected to a
Bluetooth receiver (eg. the Bluetooth symbol may appear near the battery indicator)
“let’s talk!”
Why is Bluetooth important in my practice?
• This technology is no longer just for clients who fit this demographic...
Now, this technology is applicable to ALL demographics!
So why do many users miss this opportunity?
• Market survey results
–
60% of professionals do not promote or
do not even mention wireless accessories
60% not aware
4/5 not aware but expect
–
60% of users are unaware about additional
add-on solutions
•
information
4/5 (80%) of them expected more
information!
40% aware about addons
• Possible reasons for not mentioning wireless
accessories
100% clients
–
Additional effort
–
Lack of confidence in demonstrating
*Data collected in North America and Europe indicates that demonstration and trial of
accessories leads to higher purchasing rate (N = 299 hearing aid owners).
Our wish for you and your practice….

So what can you do when your client comes to you and says “it’s not
working”?
Not anymore! We're going to teach you how to
troubleshoot wireless connections like you're Phonak
Audiology Support
•
The streamer (ie. ComPilot, ComPilot II, ComPilot Air II)
•
Bluetooth cell phone calls
•
The TVLink
•
The RemoteMic
Troubleshooting the streamer
• Conduct an audio check with the streamer to ensure proper HA and streamer function
• For ComPilot:
–
Press and hold the Connect (<>) and the Main buttons together for ~2 seconds until
audio light is purple
–
Should then hear a melody in the HAs confirming good transmission from ComPilot to
the HAs
• For ComPilot II and ComPilot Air II:
–
Turn streamer off
–
Press and hold the Main button as you turn it back on
–
When audio light goes purple let go of the Main button
–
Should hear the “Hear the World” song in the HAs confirming good transmission from
streamer to the HAs
• This will immediately rule out the HAs or the streamer as the source of the issue
If the audio check was unsuccessful…
• Ensure HA is not a “petite”, “mini”, or “NW” – they do not have a wireless antenna
• Ensure the neckloop is fully plugged in to the body of the ComPilot/ComPilot II and is
being worn around the neck
• Ensure the ComPilot Air II is within 40cm of the hearing aids (preferably at midline)
• Regroup the hearing aids and streamer
• If the audio check was successful only in one ear:
–
The wireless antenna in the other aid may be defective
–
The wires may be broken on that side of the neckloop
•
•
If you have another neckloop in the clinic, attach it to the client’s
ComPilot/ComPilot II and conduct the test again
The ComPilot Air II may be too far from that HA or there may be head shadow
•
Ensure it is being worn at midline, equidistant from each HA
Troubleshooting Bluetooth cell phone calls
The cell phone cannot find the streamer when searching for
Bluetooth devices
• Ensure both phone and streamer are actually in Bluetooth pairing mode
• The streamer may initially appear as “Headset” on some phones (until the pin code is
entered, then it will appear as “Phonak ____”)
• If you are in an area with many Bluetooth signals (eg. NOAHLink, iCube, your own cell
phone, etc.), try moving to a room with less interference
• Turn off any other accessories the client has (eg. TVLink or RemoteMic)
The cell phone and streamer paired successfully, so why can’t I hear
the phone ring in the hearing aids?
• Check that the phone says “Connected” to the streamer
–
Remember “pairing” and “connecting” are different
• Ensure that the streamer is the primary Bluetooth device for the phone (ie. ‘priority device’
or ‘primary’)
• Are the acoustic indicators turned off on either the phone or the hearing aids?
• Is the streamer charged and being worn correctly?
I can hear the phone ring in the hearing aids, but when I answer the
call, I can’t hear the caller’s voice in the hearing aids
• Make sure the client is wearing the streamer correctly
• Ensure the cell phone is not being worn in the back pocket,
this can interfere with the Bluetooth transmission (“body
shielding”)
• When a call comes in, it has to be answered using the
streamer’s main button
• If the person answers the call on the cell phone itself, the
phone will “disconnect” from the streamer and expect to be
used as ‘normal’ (ie. As a handset)
• If this is a ComPilot II and an iPhone, complete the
firmware upgrade available in Target 4.1 (from Target’s
home screen go to “Tools” > “Firmware updates” >
“Accessories”)
• When all else fails:
–
Delete the pairing from the phone and complete the
pairing process again
The phone call is successful, but the person on the other end of the
phone says they are having trouble hearing me
• Ensure the streamer is being worn correctly
–
Cannot be worn on the person’s back
–
Cannot be worn under clothing during a phone call
• Reduce the amount of background noise
• Try not to move around excessively during a call
–
The mics may be rubbing against clothing or other objects
–
The wearer may be turning their head outside of the range of the streamer’s mics
• If the wearer needs to be moving around or in background noise during calls, we
suggest getting the MC1 external microphone to clip to their lapels (for use with
ComPilot or ComPilot II)
Other Considerations
• Another issue is that the streamer may already be receiving from another device using
the same Bluetooth profile (HFP/HSP)
• The streamer may consider another cell phone the ‘primary’ phone (first one to
connect to streamer) if using the multipoint feature
• The streamer cannot accept a call on the 2nd cell phone while connected to the
primary cell phone
And don’t forget…
• An intermittent Bluetooth signal may actually be a bad cell phone signal! Have the
wearer check the number of reception bars on their phone if this happens
• The Phonak streamer is only half the equation – it may be the cell phone itself that is
the issue (eg. Bluetooth antenna malfunction inside, known bug on their end, etc.)
–
Therefore, it is always worth investigating the cell phone’s function with the client’s
cell phone provider
Unique cases/questions on cell phones you may encounter
• Flip phones
–
in order to send a call to the streamer, need to change “Answer call” option in phone
settings to “any button/key”
• Smartwatches
–
These are an extension of the phone itself, the streamer still needs to be paired with the
phone, RC App functions need to be accessed through the phone
• Easy Call I or ComPilot (original) and AB Naida CI
–
This is compatible and will stream binaurally with a Spice or Quest HA on the other ear
• iPhone 4 is not compatible with the RC App (regardless of iOS version)
• iPhones require 2 pairings to use the RC App – one within the phone’s Bluetooth menu
and one within the RC App
Troubleshooting Bluetooth TVLink connections
A point to remember about the TVLink and streamer
• Bluetooth is a one-to-one connection, it does not support broadcast streaming
• Therefore, two receiving devices (ie. two streamers) cannot be connected to one
transmitting device (ie. TVLink) at the same time.
•
For example, partners each with their own streamer, would each need their own
transmitter (ie. TVLink)
• In this case you could recommend one person use the TVLink and the other use a
RemoteMic placed in front of the TV speaker/sound system
Completing an audio check between the TVLink and the streamer
• This applies to the TVLink S and the TVLink II
• Turn off the TVLink
• Press the TVLink power button and the volume minus (-) button at the same time until the
status light starts to blink in different colors
• You should hear a test melody through the hearing aids
• This will immediately rule out any dysfunction with the link between:
1) TVLink -> streamer
2) Streamer -> hearing aids
• If the audio check is successful, then the connection between the TVLink and the TV
needs troubleshooting
If the audio check was unsuccessful, re-pair the devices
• Putting the TVLink into pairing mode:
–
TVLink S – press and hold the power button it starts flashing blue
–
TVLink II – press the pairing button [ P ] on the back of the unit until power button starts
flashing blue
• Putting the streamer into pairing mode:
–
ComPilot/ComPilot II – press and hold the volume up (+) and the Connect (<>) button
down together until the audio light starts flashing blue
–
ComPilot Air II – from the off position, press and hold the volume up (+) button as you
turn it on, release the (+) button when the audio light starts flashing blue
• When the pairing is successful, the TVLink’s flashing light will turn solid blue
The pairing was successful, but I can’t hear the TV through the
hearing aids
• Ensure the streamer is being worn correctly
• Check that the client has not pressed the Main button on the streamer, thus pausing
the signal
–
If it is paused, the blue light on the streamer will be flashing rather than solid
• Ensure the TVLink is connected to the TV properly
–
The cables must be in the “Audio Out” ports, not the “Audio In” ports
• The streamer may currently be receiving a Bluetooth signal from another A2DP device
(eg. iPod, music streaming)
–
Turn other devices off
The signal is intermittent
• Check that the cables are securely connected to the TV ports
• If the wearer uses the streamer with their Bluetooth cell phone, remember that the cell
phone takes priority:
–
If they are receiving a call, voicemail, text, or email on the phone this will be transmitted
to the hearing aids and interrupt the TV
–
Have the client turn off the acoustic indicators on the phone for anything they do not
wish to be alerted of
• If the client tells you the streaming stops after 5 mins consistently, check that the TV’s
internal volume is set to a moderate level
ComPilot and RemoteMic
Troubleshooting RemoteMic
• Re-pair the devices
–
Turn off the RemoteMic
–
Hold the “+” button while turning RemoteMic on
–
Put streamer into pairing mode
–
Light on RemoteMic will go solid when pairing is successful
• Remember that it can take ~60 seconds of stimulus into the RemoteMic for the
streamer to recognize it then switch to the appropriate streaming mode
• Ensure RemoteMic is worn within 6” of the mouth (or placed in front of audio speaker)
