Where can I get example for transfer data(file) (nRF52840)

I have 2 board nrf52840 DK, I now I want to send file ( 1~2 Mbyte) from board_1 to board_2 without use UART. where can I get example to do that ? PS: I also need example with different kit or use UART! Thanks for your help! :)

  • There is Nordic UART Service (NUS) examples which show general data transfer protocol which you may use for this. However there is no "file transfer" profile or service defined by BT SIG so I'm afraid you will need to stick with NUS or find something open source on the internet (there probably will be dozens of examples because this looks like pretty basic use case and exercise for BLE chips) or develop it yourself.

    (also would be great if you could mark correct answers to previous questions you've asked - to help people coming after you - and even close these as "answered" if it is so)
