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.
