Flyron Technology Co., Ltd. FN-BC07 MP3 Sound Module with 15W Amplifier
1) . We added this function to meet some users’ special needs that when users need to send only one frame data to play multiple tracks
one by one without pause. It supports maximum 30 tracks together for combination playback. All of the sound files used for combination
playback need to be put in folders (folder 01-folder 99).
2). If MCU/controller sends a frame data as 7E FF 15 21 01 02 01 03 01 04 01 05 01 06 02 01 03 05 04 07 05 09 EF, see the analysis as
below.
Command: 0x21
Number of bytes: 0x15=21 bytes --- FF 15 21 01 02 01 03 01 04 01 05 01 06 02 01 03 05 04 07 05 09 (two parameters for one track, i.e.
the folder number and the track number)
The module will play track 002 in folder 01, track 003 in folder 01, track 004 in folder 01, track 005 in folder 01, track 006 in folder 01,
track 001 in folder 02, track 005 in folder 03, track 007 in folder 04, and track 009 in folder 05.
3). During combination playback, it is allowed to Play/Pause and set volume, but not allowed to set Previous and Next. If need to stop,
just direct send the stop command. And it is not allowed to play another group of combination during it is working. Users need to send the
stop command to stop the current combination playback before start another group of combination playback.
4). If a track specified to be played in combination is not in the folder, it will stop playing at this track position, so please make sure the
track specified to play must be available in the folder.
5). If users are very strict to the combination playback, please edit the sound sources with some audio edit software like Adobe Audition
or GoldWave to cut off the silence at the beginning and the end of the sound.
6). Because this string of the control command is very long, we removed the bytes of “Feedback”.
3.4.11. Insert an advertisement (0x25)
Insert track "001" in the folder “ADVERT1”
7E FF 06 25 00 01 01 FE D4 EF
Insert track "002" in the folder “ADVERT1”
7E FF 06 25 00 01 02 FE D3 EF
Insert track "001" in the folder “ADVERT2”
7E FF 06 25 00 02 01 FE D3 EF
1) This module supports insert advertisements (inter-cut) during playback of a track, so that it can meet some
special needs for some applications.
2) After sending the command “0x25”, the system will save the ID V3 information of the track being played and
pause, and then it will play the specified insert track (advertisement). When the insert track is finished, the
system will go back and continue to play the track that was interrupted until to the end.
3) The setting method is to build a folder named “ADVERT1” in the storage device and put the tracks (ads) you
need in the folder and name the files as “001 .mp3/wav”, 002.mp3/wav. It supports maximum 9 folders from
“ADVERT1 to ADVERT9”, and each folder can have maximum 255 tracks.
4) If you send an insert command when the module is at Pause status or Stop status, it will not work and
there will be returned error information. In the course of an inter-cut, you can continue to insert the other
tracks (ads). When the last inserted track goes to the end, the systems till goes back to the ID V3 position
saved at the first time.
