Transfer large data 2 board nrf52840

[MainOFF]

Hello! I use 2 board nrf52840! I want to transfer large data ( 1~2MBytes) from board1 to board2 with wire to connect. Can have solution for me? (SPI I2C or uart).

Hi,

We have examples for all the different serial interfaces you list(SPI, I2C and uart). You can find them in the SDK folder SDK_folder\examples\peripheral.

You can e.g. program one of the boards with the spi example, and the other board with the spis example. When you connect the boards, you can observe that the board running the slave application receives data from the spi master board.

1. SPI communication is always initiated by the SPI master. see this post.

2. Are you getting any error codes? See this post on how to debug.
