To establish communication between spi slave and spi master!!!!

[kishor babu]

I am just trying to establish communication between spi master and spi slave.

I am using two nrf52 boards, SDK 15, in one i dumped spi master example and in another i dumped spi slave example.

I am able to transfer and receive the data.

But when I am changing the string(i.e TEST STRING) need to be transfer, it is printing the previous string only in tera term.

How can I transfer the changed string?

Thanks in advance.

Did you change TEST_STRING on both sides of the bus (both SPI and SPIS example), or only on one side?

Did you check the serial output on both sides? You should only need to change the define for the new string to be sent.

hi Jorgen,

Thanks for the reply, I solved that thing. Now it is working.

Now i am trying to add SPI master service in ble_app_uart central example and whenever i receive a data from ble_app_uart peripheral I need to send that data to the SPI slave.

could you help me in this?

Should be simple enough, initialize the SPI peripheral in main and add a call to SPI transfer function in nus_data_handler. I would recommend that you create a new question if you are having troubles with this, as this is not related to the subject of this question.
