how do you create that callback and event handler with the sdk 6.1.0 ?

Thanks, after I use the event handler, the NRF_ERROR_BUSY error is gone, but the issue is when spi_master_send_recv is called in a application timeout handler, the event handler is never got called, mean 'SPI_MASTER_EVT_TRANSFER_COMPLETED' is never received.

Yes
If you use the SPI master driver, then you initialize the driver with spi_master_init which requires that you specify spi event handler as parameter, so yes I think it is mandatory if you use the driver. Otherwise you will not get a callback once the data has been clocked out on SPI that you send/receive with calling spi_send_recv function.

I do not see that the spi_master_send_recv function throws NRF_ERROR_INVALID_DATA error. Are you using the spi_master example from SDK 7.1.0 unmodified?
