Music mode: When you insert a U disk or TF card, you can play the music files stored in it. 3. Bluetooth-compatible mode: In this mode, the telegraph will insert the English "then Bluetooth-compatible device is ready to pair" to show that it has entered the Bluetooth-compatible mode and waits for a matching connection; the mobile phone opens the Bluetooth-compatible search for "HW-BT" and connects; when the connection is successful, the decoder board will have an English prompt "the Bluetooth-compatible 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. Note: Please allow 1-3mm differs due to manual measurement.
