4. Application DemonstrationThis chapter describes how to
establish a WST connection between two IS2066B EVBs and a host
device, andperform Audio Streaming and Auto Role Switch
demonstration and HSP/HFP demonstration. It also demonstratesthe
process of updating the parameters using various tools.
4.1 Establishing a ConnectionTo establish the Bluetooth
connection between two IS2066B EVBs and a host device, perform the
following actions:
1. Set the mode selection switch (SW301) to Application mode on
both EVBs, see Table 3-1.2. Connect the 4-pin headphone provided in
the kit to the audio jack (P1) on both EVBs.3. Connect the 4.2V
battery to the battery connector (J201) on both EVBs.4. Connect the
antenna provided in the kit to the SMA connector (CN301) on both
EVBs.5. Make sure that the 5V On/Off switch is in the ON
position.6. Connect the USB cable from a PC host (or a USB power
source) to the Micro-B USB port (J701) for both
EVBs.Note: The two EVBs in the IS2066B EVB kits are
pre-programmed and pre-paired with the WST application.
Figure 4-1. Using the Evaluation Board
7. Observe that the LEDs for both EVBs turn on. It is simulated
as an IN-BOX condition (that is, both left and rightinside the
charger box) and the EVB units perform automatic WST pairing
(primary and secondary) when theyare placed close to each other.The
WST pairing only takes 2-3 seconds. If the pairing process is
successful, then:
– The EVB with the red LED blinking changes to steady red, which
indicates that it is the secondaryearbud.
– The other EVB with the blue LED blinking remains the same,
which indicates that it is the primary earbud.– If the pairing is
not successful, then both ear buds show a blinking red LED.– Power
cycle (SW201 5V turn off and on again) both EVBs and start
again.

8. Turn the SW201 5V supply to the OFF position for both EVBs
and observe the LED blinking for a very shortperiod and remains the
same as step 7. It is simulated as an OUT-BOX condition (that is,
both the left andright outside the charger box) now. The user can
perform smartphone or Bluetooth source pairing as listedbelow:
– Press the MFB button for 1s and release.– Observe red and blue
LEDs blinking alternatively on the primary side, voice prompt
“ready to pair” should
be heard as well. Secondary side LED remains a steady RED.– In
your smartphone device, turn on Bluetooth and connect to the
“WSTxxx” device.
Once the connection is established, the LED of the primary EVB
turns to steady blue, and the LED of thesecondary EVB remain a
steady red. The device name on the smartphone is displayed as
“connected” in theBluetooth settings. With the default settings,
the IS2066B EVB enables the Advanced Audio Distribution
Profile(A2DP) for audio playback and Audio Video Remote Control
Profile (AVRCP) for player control.
4.2 Audio Streaming and Auto Role Switch DemonstrationPerform
the following actions to stream out audio on the IS2066B EVB using
a host device (a PC or a smartphone).
1. Establish the connection between the IS2066B EVB and a host
device using the procedure listed in 4.1 Establishing a
Connection.
2. Once the connection between the IS2066B EVB and the host
device is established, open the audio source onthe host device.
Microchip recommends using a media player.
3. Press the MFB button for play/pause on either the primary or
secondary EVB.4. Auto role switching during music streaming can be
performed as mentioned below:
4.1. Turn on the 5V power switch (SW201) for the primary side
EVB (simulate IN-BOX for primary), musicstreaming should continue
at the other side, auto role switching (secondary side becomes
primary)should be performed as well.
4.2. Turn off the 5V power switch (SW201), EVB should link back
automatically as secondary andcontinue the music.
4.3. Turn on the 5V power switch (SW201) for secondary side EVB
(simulate IN-BOX for secondary),music streaming should continue at
the other side.
4.4. Turn off the 5V power switch (SW201), unit should link back
automatically as secondary and continuethe music.
4.5. Turn on the 5V power switch (SW201) for both primary and
secondary side EVB (simulate IN-BOXfor both sides), connection to
the smartphone or Bluetooth sources should be disconnected.
5. Power-off EVB:– For both IN-BOX and OUT-BOX state, long press
MFB by 5s to turn off the EVB.– If the battery is fully charged
(IN-BOX state), the EVB turns off automatically after 20s to save
power
consumption.6. Perform the following procedures to Master Reset
(clear all pairing record) the IS2066B EVB:
6.1. Turn off the 5V power switch (SW201) for both EVBs, to
simulate both EVBs as OUT-BOX.6.2. Make sure the EVB is in shut
down condition by pressing the MFB button for 5s, and wait until
the
"shut down" tone is audible.6.3. Long press MFB for more than
20s until the red and blue LEDs blink 5 times.6.4. Each EVB can be
Master Reset separately.6.5. After Master Reset, the earbud turns
off with no LED indication.6.6. After master reset, the earbud must
be put back to the charger box for left and right earbuds to
link
up (WST pairing) before further testing.

Microchip Devices Code Protection FeatureNote the following
details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their
particular Microchip Data Sheet.• Microchip believes that its
family of products is one of the most secure families of its kind
on the market today,
when used in the intended manner and under normal conditions.•
There are dishonest and possibly illegal methods used to breach the
code protection feature. All of these
methods, to our knowledge, require using the Microchip products
in a manner outside the operatingspecifications contained in
Microchip’s Data Sheets. Most likely, the person doing so is
engaged in theft ofintellectual property.
• Microchip is willing to work with the customer who is
concerned about the integrity of their code.• Neither Microchip nor
any other semiconductor manufacturer can guarantee the security of
their code. Code
protection does not mean that we are guaranteeing the product as
“unbreakable.”
Code protection is constantly evolving. We at Microchip are
committed to continuously improving the code protectionfeatures of
our products. Attempts to break Microchip’s code protection feature
may be a violation of the DigitalMillennium Copyright Act. If such
acts allow unauthorized access to your software or other
copyrighted work, youmay have a right to sue for relief under that
Act.
