Hi, I want know how upload and download mp3 file to SD card. Something like: Send: microphone -> music shield -> mp3 -> SD card -> upload mp3 to internet server; Receive: download mp3 from internet server -> save to SD card -> music shield -> speaker; Should I use HTTP POST GET or TCP?

The idea work like voice message: voice to mp3, and mp3 to speaker. So I want find way send and receive mp3 file with server. I find spark core support tcp, but good send string. If I need upload and download mp3 file, I think should use something like ftp?

@rhoulay , you could use a VS1053 breakout like this one: [image] VS1053 Codec + MicroSD Breakout - MP3/WAV/MIDI/OGG Play + Record This breakout board is the ultimate companion for the VLSI VS1053B DSP codec chip. The VS1053 can decode a wide variety of audio formats such as MP3, AAC, Ogg …

This is definitely do-able. I’ve done the same with downloading an image into flash and then displaying it on a display connected to the Core. I download over HTTP in “chunks” so all I have to do is host the image file on any normal web server. Would this work for you?

@harrisonhjones , I’d love to see that code! :stuck_out_tongue_winking_eye:

Good one, In sweden we don’t have this :wink:

@harrisonhjones Yes, I think image and audio file are same thing in this case. And how you upload and download file with HTTP?

@rhoulay , @peekay123 , I’ll try to package the code up and put it on a gist tomorrow. Ping me if you don’t hear anything by Saturday

@harrisonhjones hi, how about your sample code?

Hey, this code is crazy rough and not all of its actually there but the general gist is there. Read through it and ask any questions if you are unclear. https://gist.github.com/harrisonhjones/7f7eb97600069279e16e application.cpp /* Includes --------------------------------------------------…

Hi, @harrisonhjones I find you use some custom function and variable not include in your sample code. Could you include that code? And how about the main setup and loop flow for spark core?

Here's the chunking library I created. Still early, but it works.
