Music Maker with nRF52840

Post by prahsman »

Can the VS1053 Music Maker shield be used together with the nRF52840? Can the nRF52840 be used to retrieve/play mp3 files from an iOS phone?

Which nRF52840 board do you want to use? This one? https://www.adafruit.com/product/4062

Yes. Do any of the pins conflict? Currently I use the Feather to play mp3 data which is supplied externally via DMA. I was wondering how hard it would be to receive mp3 data via a iOS cell phone and play it back.

To further clarify, I would like to stream existing mp3 files residing on an iphone through the nRF52840 (via BLE) and use the VS1053 feather as the decoder. Will that work?

BLE isn't fast enough to transmit audio data. In practice, you can expect maybe a few tens of kilobytes per second. Audio requires a much higher bitrate.

Bluetooth audio devices use the protocol now known as Bluetooth Classic, which operates at 1Mbps. Unfortunately BT-C is actively unfriendly to hackers, among other things requiring a Vendor ID that costs about $5k per year.
