sent out within the time, indicating that the module initialization error, please reset the module's power supply, 
and detect hardware connecting; 
2).The module initialization data including online devices, such as sending 7E FF 06 3F 00 00 01 xx xx EF, DL 
= 0x01 describe only the U-disk online during power-on, Other data are seen as the table below:

3).MCU  will  not send  corresponding control  commands  until  module initialization  sending commands  or  the 
module  will  not  process  the  commands  sent  by  MCU,  and  will  also  affect  the  normal  initialization  of  the 
module.

1.The module will enter into pause status automatically  after  being  specified  playing,  if customers need 
such  application,  they  can  specify  track  to  play  ,the  module  will  enter  into  pause  status  after  finishing 
playing ,and wait for the commands sent by MCU. 
2 In addition, we opened a dedicated I/O as decoding and pausing status indication. See Pin 16, Busy 
1).Output high level at playback status; 
2).Output low level at pause status and module sleep; 
3. For continuous playback applications, it can be achieved as below, if it finishes the first tracking of the 
TF card, it will return 
7E FF 06 3D 00 00 01 xx xx EF 
3D ---- U-disk command 
00 01 ---- expressed finished playing tracks. 
If the external MCU receives this command, please wait 100ms. And then sending the playback command 
[7E FF 06 0D  00 00 00 FF EE  EF], because inside the module it will first initialize the  next  track 
information. In this case, the module can be played continuously. 
4. If the currently finish playing the first song, the track pointer automatically point to second song, If you 
send  a "play  the next one”  command, then the  module  will playback the  third  song. And, if  the  module 
finishes playing the last one, the player will automatically jump to the first pointer, and pause. 
5. After specifying device, the module  play  pointer  will point to device root directory  of  the  first track, 
and enters the pause state, and wait MCU sending track playing command.
