1. INTRODUCTION
IS1690S_255 Multi-Speaker (Called n-SPK in this document) is a Bluetooth speaker solution. It supports voice and audio output,
phone call control and music remote control. Besides, two n-SPKs can be combined to form a pair of speakers with surround
sound effect by a special wireless technology.
This document describes the UI configuration tool which provides a friendly interface to edit parameters of the n-SPK. The
configuration determines the operations, indications and capability for the n-SPK. The customers can create their products they
want by adjusting the configuration.

2. NOMENCLATURE
2.1 MFB
MFB(Multiple Function Button) is a specific button that can be used for turning on/off n-SPK and general purpose functions.
2.2 Pairing Mode
If n-SPK is in Pairing Mode, it is discoverable and waiting for remote devices to connect to.
2.3 Single Mode
If n-SPK doesn’t have a connection with another n-SPK and isn’t pairing with it, the state of the n-SPK is called Single Mode
2.4 Twin Mode
The n-SPK has a connection with another one or is pairing with it the state of the n-SPK is called Twin Mode.
2.5 Twin Speaker Link
The connection between a pair of n-SPKs is called Twin Speaker Link.
2.6 Twin Master
Twin Master is the n-SPK which initiates a Twin Mode Link and it may has a connection with a remote device such as a phone
at the same time.
2.7 Twin Slave
Twin Slave is an n-SPK as the slave role of Twin Mode Link, waiting for Twin Master to establish a Twin Mode Link. When an n-
SPK is the role of Twin Slave, it can’t have a connection with a remote device.
2.8 Twin Speaker Pairing
Twin Speaker Pairing is the process of a Twin Master try to pair and create a connection with a Twin Slave.

3.2 Main Features Page
When you start to edit UI parameters, you will see Main Features page as Figure 3.2. At first, this page lists some main features
and shows the settings of the loaded UI parameter table. Then you can modify it to achieve what you want.
There is one thing need to pay attention. Some I/O pins may be configurable to perform different features, they are called multifunction pins. In the configuration, one multi-function pin should be map to only one feature. To avoid that several features may
use the same pin, if a pin is occupied by a feature, the other features using the same pin will be unchecked and disabled
automatically. Below it will have a brief for the features in this page.
Figure 3.2 Main Features
3.2.1 Supported Profiles
Determine that the product supports which Bluetooth profiles.

3.2.3 Power On Enter Twin Mode Pairing Setting
For twin mode pairing setting, n-SPK can be set to stay one of predefined modes when it is turned on. These predefined modes
are described as below
3.2.3.1 Single Mode
Enter Single Mode after n-SPK is turned on.
3.2.3.2 Back To Last Mode
After n-SPK is turned on, it enters into the last mode which n-SPK stayed before powering off. For example, if n-SPK is in the
Single Mode before it is powered off, it will enter into Single Mode in next powering on.
3.2.3.3 Intelligent Twin Pairing
When n-SPK is powered on, it enters Twin Mode Pairing and tries to discover a matched n-SPK to create a connection upon the
presetting group code. The roles of Twin Master and Twin Slave are determined by automatic negotiation between the two
matched n-SPKs.
3.2.3.4 Factory Paired
Two n-SPKs are pre-paired and assigned the roles of Twin Master and Twin Slave in production. These two n-SPKs will try to
establish the connection after they are powered on.
3.2.3.5 Switch Control
There are two pins which are P2_4 and P3_0 determine the behavior of n-SPK. The corresponding roles of these two pins are
mutually exclusive and could be configured to be Twin Master or Twin Slave. That is, if P3_0 is set to Twin Master, P2_4 must
be Twin Slave. Base on above configuration, If P3_0 is pulled to high when n-SPK is powered on, n-SPK will enter Twin Mode
Pairing as Twin Master. And it will be Twin Slave if P2_4 is pulled to high. If P3_0 and P2_4 are both pulled to low, n-SPK will
enter Single Mode when it is powered on.
3.2.3.6 Always Twin Pairing Entry(With Twin Paired Record)
If n-SPK has paired records of Twin Mode Pairing, it enters Twin Mode Pairing when it is powered on else it enters Single Mode
3.2.4 Other Features
3.2.4.1 Slide Switch(P3_4)
This configuration determines that the product is turned on and turned off by slide switch with the pin P3_4.
3.2.4.2 Aux Line-in
Support Aux-in function as audio input by an Aux-in wire.
3.2.4.3 NFC Detection(P0_4)
Support NFC (Near Field Communication) function with the pin P0_4. It can achieve automatic Bluetooth connection and
disconnection upon APPs design on remote devices when NFC function is triggered.
13
3.2.4.4 External Amplifier(P0_0)
Support to indicate that audio outputs with an external amplifier by the pin P0_0.
3.3 Function Settings Page
=>
Pressing the Next button on Main Features described above will pop up Function Settings page. Function Settings provides
more detailed configurations. The settings of Main Features will affect some parameters on Function settings page. Base on the
settings of Main Features, some detailed configurations may be fixed or reduce selections. For example, once a profile is
disabled in the configuration of supported features, all settings related to this profile will be canceled.
And there is a button in bottom left corner that can back to Main Features if something need to change. When the editing was
done, pressing the Finish button in bottom right corner to back to Start Menu described above. Then you can save the editing
as a UI parameter table.
There are so many parameters in Function Settings page you can get more information in the next chapter. Function Settings
3.4 Power Switch Setting
The power switch configuration has four types and determines which pattern is used in n-SPK. These four types are listed as
below.
3.2.1 MFB Power ON/OFF
Turning on and turning off n-SPK depends on the duration of pressing MFB button. The related settings are Power On Duration
and Power Off Duration. That is, if users keep pressing MFB key over the configurable time, n-SPK will be turned on or turned
off. Please refer to 4.9.1 Button Press Duration for more information.
14
Figure 3.3 MFB Power ON/OFF reference circuit
3.2.2 Power On Directly
The n-SPK is controlled directly by power source. When n-SPK connects to power source such as a battery and a plus to MFB
Pin, it is on, otherwise it is off.

3.12 Button Settings
By operating buttons, n-SPK can achieve some functions such as playing music, answering a call and so on. Here it will
describe how these buttons work and what operation can be performed.
The button operations divide into five types by pressing time: Power On, Power Off, Short Press, Long Press and Double Click.
Besides, it may define a combined key by pressing arbitrary two buttons simultaneously. Power On and Power Off events
triggered by MFB are only for turning on and off n-SPK. The others perform functions base on the settings of button function
listed as 4.9.4 Button Functions.
3.12.1 Button Press Duration

If pressing a button over this time it will trigger Long Press event, else it will have a Short Press event.
There are two more settings that may set to repeat Long Press event when the button is kept pressing:
Long Press Repeat Mask
This setting determines which buttons support the function of repeating Long Press event.
Note that MFB does not support this special setting.
Long Press Repeat Time
Configure the interval between two continuous Long Press events when the button is kept pressing.
When you need special key settings, support as below.
3.12.1.4 Double Click Recognize Period
In general, Double Click means pressing the same button twice quickly. It needs a value to define how quick these two
pressings should be. This setting is to determine that these two pressings become a Double Click event or two Short Press
events. If the interval between two continuous pressings is less than this setting, n-SPK will generate an event of Double Click
event else it will has two events of Short Press. And the corresponding functions will be triggered. (Unit: 80ms)
3.12.2 Special Key Setting
It defines two kinds of button behavior as Special Key, one is Double Click and the other is the combined key pressing two
buttons simultaneously. The combined key may trigger an event of Short Press or Long Press. It supports two pre-defined
Special Keys in n-SPK.
25
3.12.3 Function Mapping Table
The Function Mapping Table is to set the functions for the triggered events in all states that divided by call status. There are
three kinds of button events in the Function Mapping Table; Short Press, Long Press and Special Key. If a function is set to
certain button event, it means the function will be performed when this button event is triggered. For example, if the function
Forward is set to the Short Press event of Button4 in Standby (No talk) state, when users short press Button4, the music will
forward to next track. More information about performed functions and call states will be described later.
3.12.4 Combined Function Table
The Combined Function Table is an expanded function of button settings and divided into two classes which are classified
according to profile links states and according to music streaming states. There are four kinds of button functions are called
Combine Function0, Combine Function1, Combine Function2 and Combine Function3(See 3.12.6 Button Functions). These four
button functions can be set in normal key operation and special key operation and are triggered in the Function Mapping Table.
If one of them is triggered, the corresponding button events will be triggered by profile links states and music streaming state.
Under the profiles links state, these states are called No Link, Only A2DP, Only Mono and Two Links; under the music streaming
state, they are called AV Idle and AV Play. If Combine Function0 and Combine Function1 are set and clicked to perform, the
corresponding actions will be took and based on profiles links states; if Combine Function2 and Combine Function3 are set and
clicked to perform, the corresponding actions will be took and based on music streaming states. For example, if the Combine
Function0 is set to the Short Press event of Button4 under Standby (No talk) state in the Function Mapping Table and the
Play/Pause is set in Combine Func0 at Two Links in the Combine Function Table, users press Button4 shortly under
Standby(No talk) state, the player will start to play or pause music.
26
3.12.5 Call State
