1.1 Product introduction
BTI-029 is a stereo receiver/transmitter two-in-one Bluetooth optical fiber adapter, with a range of 10 meters, and the Bluetooth version: V4.1.
*Can be with support bluetooth function(A2DP protocol)Speakers or headphones to connect(In TX state), You can also connect with your mobile phone or computer(In RX state).
*BTI-029 supports (Dual stream) one for two function (one BTI-029 can connect two speakers or headphones at the same time, and listen to music at the same time); BTI-029 also supports multi-point connection(One BTI-029 is connected to two mobile phones at the same time. At present, only one mobile phone can play music and it can sound, and which phone is the first to sound. If you want to switch to another mobile phone to play music, you need to change the current Music pause of the phone playing music).
*BTI-029 supports CODECs such as APT-X and SBC.
*BTI-029 supports optical input and optical output
1.2 Operating instructions
* BTI-029 is to choose the transmitter mode or receiver mode after turning on the switch by flipping the switch. When it is off, turn the switch to ”TX(emission)On the ”end, press and hold the “multifunction button” to turn on the device. After turning on the device, all paired device information in the RX (receiver) state will be cleared!!! In addition, within three seconds after turning off It is not possible to switch the TX/RX state immediately, because the chip has not been completely powered down. If the switch state is at this time, it may still be turned on in the state before the shutdown.
* When BTI-029 is used as a transmitter, it can store 4 device information, and the excess will be replaced by new device information(Why are 4 stored? Because the BTI-029 will connect back to all paired devices after booting up, if there are too many, the connection time will be too long.)

The reconnection time of the four devices is 22 seconds.
*1, Power-on (TX): In the power-off state, long press the “multi-function button” for three seconds, after the blue light flashes twice, BTI-029 is turned on, when the pairing list is empty(BTI-029 has not been connected to any equipment), It will automatically enter the pairable state with the blue light flashing quickly after power on.
*2, Shutdown (TX): In the power-on state, long press the “multi-function button” for three seconds, the red light flashes twice(If you let go immediately after seeing the red light, the red light may only flash once)BTI-029 is turned off after it is turned off; it cannot be turned on immediately within 3 seconds after it is turned off because the chip voltage has not disappeared.
*3, Enter the pairable state (TX): After booting in any state, double-click the “multi-function button” to enter the pairable state where the blue light flashes quickly.
*4, Clear the pairing list (TX): current status(RX /TX status)After shutting down, wait 3 seconds to switch to another state(TX/RX)Then turn it on again, the information of all connected devices in the previous state will be cleared.
*5, Connect back to all connected devices (TX): power-on disconnected state or power-on connected state(Use when one with two functions), Short press the “multi-function button” to connect back to all connected devices(The connected device may pause or stop during the connection process); Or every time BTI-029 is turned on, it will automatically connect to all connected devices(But only two devices can be connected at the same time, the last two devices are given priority), The connection is successful, and the BTI-029 turns to a steady blue light; if no device is connected back, the time exceeds 22 seconds(The specific time depends on how many devices have been paired)Automatically switch to pairable mode. When used as a transmitter, BTI-029 can make two devices sound at the same time(This is the transmitter one with two functions).
*6, Automatic shutdown (TX): When the battery voltage is lower than 3.1V, BTI-029 will automatically shut down.
*7. Use BTI-029 (TX) when charging: When BTI-029 needs to be used for a long time, because the built-in battery has a limited use time, it can be allowed to connect to the charging power supply(DC 5V≥300mA, when the battery power is too low or the power quality is poor, it may cause the current sound to appear);Please note: It is not recommended to use this function frequently when charging, otherwise it may affect the battery life
*8, In the off state or working state, you can switch between AUX and SPDIF by flipping the switch.
*9, Boot (TX): The blue LED flashes twice before booting.
*10, Shutdown (TX): Shut down after the red LED flashes twice.
*11, Pairing mode (TX): The blue LED flashes.
*12, Disconnected standby state (TX): The blue LED flashes once every second.
*13, Connected standby state (TX): The blue LED is always on.
*14, low battery state (TX): red LED flashes(Charging immediately or shutting down can release this state).
*15, Charging in progress (TX): The red LED light is always on.
*16, Fully charged (TX): The red LED is off.
When used as a receiver
* BTI-029 is to select transmitter mode or receiver mode after power-on by flipping the switch. When it is off, turn the switch to ”RX(receive)On the ”end, press and hold the “multi-function button” to turn on the device, and all paired device information in the TX (transmitter) state will be cleared after turning on the device!!! In addition, within three seconds after turning off It is not possible to switch the TX/RX state immediately, because the chip has not been completely powered down. If the switch state is at this time, it may still be turned on in the state before the shutdown.
? BTI-029 can store 8 device information when used as a receiver, and the excess will be replaced by new device information(Each time the receiver stores 1 more device information, the time for the receiver to automatically enter the pairable state will increase. The reconnection time of BTI-029 is: if a device is paired, the reconnection time is 7 seconds, and the time for pairing is two. The reconnection time for two devices is 12 seconds, the reconnection time for three devices after pairing is 17 seconds, and the reconnection time for four devices after pairing is 22 seconds).
*1, Power-on (RX): In the power-off state, long press the “multi-function button” for three seconds, after the blue light flashes twice, BTI-029 is turned on, when the pairing list is empty(BTI-029 has not been connected to any equipment), It will automatically enter the pairable state after booting.
*2, power off (RX): in power on state, long press “multi-function button” for three seconds, the red light flashes twice(If you let go immediately after seeing the red light, the red light may only flash once)BTI-029 is turned off after it is turned off; it cannot be turned on immediately within 3 seconds after it is turned off because the chip voltage has not disappeared.
*3, Enter the pairable state (RX): in any state after booting, double-click the “multi-function button” until the BTI-029 red and blue lights flash alternately to enter the pairable state, and the pairing state exceeds five It will automatically shut down if it is not paired in minutes.
*4, play/pause(RX): When playing music, short press the “multi-function button” to pause/play the music.
*5, Clear the pairing list (RX): current status(RX/ TX status)After shutting down, wait 3 seconds to switch to another state(TX/RX)Then turn it on again, the information of all connected devices in the previous state will be cleared.
*6, Connect back to all connected devices (RX): BTI-029 will automatically connect to all connected devices every time it is turned on(But only two devices can be connected at the same time, and the last two devices connected will be connected first), The connection is successful, the BTI-029 turns to the blue light, and when it is used as a receiver, the BTI-029 can only send out the device that played music first. If the other device wants to make a sound, you must turn off the previous one. Music or pause music(This is the receiver one with two functions).
*7, automatic shutdown (RX): when the battery voltage is lower than 3.1V, it will automatically shut down; if there is no pairing record, it will automatically shut down after 5 minutes if it is not connected; if the product has a pairing record, it will not be connected for more than 6 minutes It will automatically shut down, and it will take about 1 minute for the product to try to connect back.
*8. Use BTI-029 (RX) when charging: When BTI-029 needs to be used for a long time, because the built-in battery has a limited use time, it can be allowed to connect to the charging power supply(DC 5V≥300mA, when the battery power is too low or the power quality is poor, it may cause the current sound to appear);Please note: It is not recommended to use this function frequently when charging, otherwise it may affect the battery life
