CC85XXDK-HEADSET Quick Start Guide
1. Kit Contents
The following items are included in the
CC85XXDK-HEADSET:
2 x CC85XX Headset boards
2 x Battery
1 x CC Debugger
1 x USB micro cable
1 x 3.5mm jack to 3.5mm jack cable
Documentation
If anything is missing in the CC85XXDK-
HEADSET please contact your local TI
sales representative.
Caution! The kit contains ESD
sensitive components. Handle
with care to prevent permanent
damage.
2. Purpose of this Quick Start
Guide
This quick start guide will provide step-by-
step instructions showing how to set up an
audio link between two wireless units
provided in the development kit.
The CC8531 on each of the boards are
pre-programmed with firmware to stream
audio from the Master microphone input to
the Slave headphone output. Please
follow step 3 to 9. Information on how to
upgrade with latest firmware, see step 10.
For more details on CC85XX, see the
product folder of the CC8520 [1].
Performance and functionality of the
CC8531 are strongly dependant on the
firmware. Thus, for performance testing
etc make sure the firmware used is the
latest released firmware from the TI web
site, see step 10.
3. Plug the batteries to each of
the Headset boards
There’s only one way to connect the
battery plug to the socket on the board.
With the pre-programmed firmware the
CC8531 enters the OFF power mode
when the battery is connected. The
batteries should have enough charge out-
of-the-box to establish a link and stream
audio. To charge the battery, see section
9. With full battery the link should run for
typically 15 hours, the Master being the
bottleneck. The Slave plays audio for 22
hours typically.
Warning! Always use the battery supplied
with the kits with the CC85xx Headset
boards.
4. Power up both boards
In the pre-programmed firmware the
toggling between power modes OFF and
ON is mapped to pressing the rocker
switch IN for 1.6 seconds. The two boards
are unpaired out-of-the-box, so in the ON
power mode the topmost LED should flash
once every second indicating network
state ALONE . In the OFF power mode
the LED is turned off. Make sure both
boards are flashing.
Caution! To minimize risk of injury, avoid
touching components during operation if
symbolized as hot.
Do not leave EVM powered when
unattended.
5. Connect an audio source to
the Master
Connect an audio source (CD-player,
MP3-player or similar) to the line in
connector on the Master Headset board
(labeled Master on the back side) via the
3.5mm jack cable.
The Master is pre-programmed with
firmware to set up the onboard
TLV320AIC3204 codec [2] to power down
the DAC and use the line in connector as
source to the ADC input.
6. Connect a headphone to the
Slave
Connect a headphone to the 3.5mm
headphone output on the board labeled
Slave on the back side.
The Slave is pre-programmed with
firmware to set up the onboard
TLV320AIC3204 codec [2] to power down
the ADC and have the headphone
connector as destination of the DAC
output.

7. Pairing
In the pre-programmed firmware the
pairing button is mapped to pressing the
rocker switch IN (not hold, which is power
toggling as described in 4).
Press the pairing button on either board
and observe that the LED blinking pattern
changes. It will now flash two times per
second which indicates that the device is
trying to pair with another device.
If the pairing button on the other board is
pressed within 10 seconds the devices will
pair. The Master status LED will be
constantly lit, and the Slave status LED
will flash once every 2.5 seconds. Audio is
now being streamed to the Slave.
When successfully paired the Slave will
save the Master’s device ID in non-volatile
memory and automatically try to pair with
this Master whenever in the ALONE state.
Thus pressing the pairing buttons again
will no longer be necessary (unless the
Slave is re-programmed or paired with
another Master).
8. Volume control
The pre-programmed Slave firmware is
configured to have so-called “local volume
control” meaning that the Slave controls
its own volume locally. The volume
buttons are mapped to clicking/holding the
rocker switch UP and DOWN.
9. Charging
To charge the battery, simply connect the
USB micro cable while the battery is also
connected. The charge voltage should be
5V (plugging the USB cable in your
computer will work perfectly). The bottom
LED will be lit indicating charging. When
the battery is fully charged the LED will go
dark.
The Headset board can be powered from
USB alone (remove the battery and
connect USB cable). Then the LED will be
lit the whole time.
Audio can be streamed while charging.
For information about the single chip
charger and DC/DC converter, see [4].
10. PurePath Wireless
Configurator
The next step is to download the PurePath
Wireless Configurator (PPWC) [3]. PPWC
makes it possible to explore all the
configuration options of the CC85XX
family. After creating device configurations
for Master and Slave network roles,
PPWC can program the CC85XX devices
directly through the CCDebugger
(included in the kit).
