-------------------------------
Summary: [NEWT/NORDIC] Transfer audio files from PC to Adafruit
board, then sending via BLE
Key: MYNEWT-892
URL: https://issues.apache.org/jira/browse/MYNEWT-892
Project: Mynewt
Issue Type: Wish
Security Level: Public (Viewable by anyone)
Components: ble, Filesystem
Affects Versions: WISHLIST
Environment: PC: Window/Linux
Phone: iOS/Android
Reporter: DINH LAM
I am using an adafruit-nrf52-pro-feather (nrf52832) to run my project of
detecting voice by this below scenario:
++ Setting up:
[PC] ==== USB cable =====[Adafruit] * * * BLE * * * [Phone]
+ Audio files are very small size (less than 100kB or 20 seconds), with ADPCM
format
[http://www.kowatec.com/prod/ap/products.php?a=adpcm]
+ USB cable which is delivered together with the board, but currently I am
using as UART port for monitoring serial log.
I still have some concerns for this scenario as:
1) For transferring audio files from PC to the Adafruit, what are the available
approaches ?
Is there any way to use the same USB cable and still have UART port debugging
normally?
2) I suppose it would stay in RAM by default, but is Ada RAM enough for the
above size?
3) Can I send the file (in RAM) directly via BLE or I need to do somethings
else before sending via BLE?
I appreciate any suggestions/helps or some reference links.
Best Regards,
James, Dinh
