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.
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...
3. TOOL OVERVIEW There are three parts in UI configuration tool; Start Menu, Main Features and Function Settings, will be introduced in the following sections. 3.1 Start Menu Page After launching this tool, first view you see is Start Menu. It consists of two blocks, information block and operation block as Figure 3.1 Figure 3-1 Start Menu Page 3.1.1 Operation...
3.1.2 Information Block 3.1.2.1 IC Package Display the IC package. 3.1.2.2 Module Name Display the Module name if it has. 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.
3.2.1.1 HFP(Hands-free Profile) Support voice input/output and some call operations. 3.2.1.2 A2DP(Advanced Audio Distribution Profile) Support audio output.. 3.2.1.3 AVRCP(Audio/Video Remote Control Profile) Support audio remote control. AVRCP Controller Support controlling the music players of remote devices such as play/pause, forward and rewind. All supported controls can be triggered by buttons of an n-SPK upon the settings of button events.
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.
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.
3.5 NFC Setting The n-SPK offers a convenient way to establish and terminate Bluetooth connection by NFC. To get the benefits, n-SPK must have an NFC tag with its Bluetooth address and some related information and remote devices need to support the NFC feature. The remote device just touch the NFC tag of n-SPK, it will get the information of n-SPK, and APPs on the remote device may deal with Bluetooth connection or something.
3.7.1 Maximum Paired Device Determine the number of paired devices that can stored in n-SPK. It is eight at most. 3.7.2 Link Back Scheme The scheme of reconnection is to connect to the last device which is the highest priority or the paired devices with priority-based. 3.7.3 Pairing Mode Duration The configuration is the duration that n-SPK is discoverable.

Now this setting is fixed to 100% and isn’t allowed to modify. That is, the value of above Charging Current setting equal to battery capacity.
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.
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.
3.12.5 Call State It defines several states below upon call status. 3.12.5.1 Standby(No Talk) Mode Two conditions belong to this state; n-SPK has no connection with a remote device or n-SPK has no actions related to call. 3.12.5.2 Voice Dial Mode The remote device connected with n-SPK is processing voice dialing.
3.12.6 Button Functions The functions below may be performed by button operation upon the settings of Function Mapping Table. When pressing a button, the corresponding action will be performed. 3.12.6.1 N/A (0x00) No action. 3.12.6.2 Force End Call(0x02) End the current active call no matter the voice sound is outputted by the local side and remote side. 3.12.6.3 Answer(0x04) Answer the incoming call.
