Hi ,
I'm facing the same problem:

spi without softdevice works
bel_app_uart + spi is not working

I'm calling nrf_drv_spi_transfer and waiting till "NRF_ERROR_BUSY" is gone.
But it stays busy forever.
Were you able to solve your problems?

Best

Felix

I'm assuming you're calling nrf_drv_spi_transfer() SIX times. If that's the case, you're calling "nrf_drv_spi_transfer" too fast. You don't let the previous transfer finish before you start another.

I'm not sure what you mean by "6 types of data", but you can just put all of your data in a larger tx_buffer, and then pass its pointer to the nrf_drv_spi_transfer(). That way you would only need to use nrf_drv_spi_transfer() ONE time.

You could also write your nrf_drv_spi_transfer() functions in the spi handler(). The handler will run whenever a transfer is complete, so by having your functions in there, you avoid any transfer() overlap.
