Array data transmittion by spi

[Kaito]

Hi!

I have added programs for register writing to SPI programs and using SDK14.0.0

I am using the nrf_drv_spi_transfer function to transfer three data.

but when confirming the output of the log by Tera term,

"test1" after nrf_drv_spi_transfer could not be confirmed and "test" could be confirmed.

Therefore, it can be said that the nrf_drv_spi_transfer function is causing an error.

But I do not know why the error is occurring.

please teach me the solution.

thank you in advanced.

Hi,

Please debug the application using this method, to find which function returns an error code, and what the error is.

Best regards,
Jørgen
