Operation Manual:
1. Mode control: When the decoder board has no U disk or TF card, the default mode is Blue tooth when the module is powered on. When the decoder board is plugged in with U disk or TF card, the default mode of module power-on is music mode.
2. Music mode: When you insert a U disk or TF card, you can play the music files stored in it.
3. Blue tooth mode: In this mode, the telegraph will insert the English "then Blue tooth device is ready to pair" to show that it has entered the Blue tooth mode and waits for a matching connection; the mobile phone opens the Blue tooth search for "HW-BT" and connects; when the connection is successful, the decoder board will have an English prompt "the Blue tooth decvice is connected succesfully", and then the decoder board can play music.
Warm Tips:
1. If the U disk is playing, it is recommended to use USB 5V power supply (not 3.7V lithium battery power supply), because the early U disk does not support 3.3V voltage.
2. U disk or TF card, decoding only supports FAT16/FAT32 file system, not NTFS.
