Bluetooth Transmitters (including TT-BA01, TT-BA10, TT-BA11, TT-BA07/TT-BA08/TT-BA09 /TT-BA12 in TX mode) support stay on when it is charged. When you keep the transmitter charged by a 5V external charger such as Android power charger (instead of the USB jack of TV) via Micro USB Power Cord, then you turn on the last paired Bluetooth headphones or speakers, they would automatically pair with Bluetooth transmitters!


Bluetooth Receiver (including TT-BA07/TT-BA08/TT-BA09/TT-BA12 in RX mode) does not support stay on or re-connect feature, it will auto power-off while there is no any paired device.
