Thanks it worked

Have you checked if you have any assert (e.g. code has run to fault_handler)?

I am able to transfer the data to another nrf but after the spi transfer my board goes to deadlock the able stops.

I tried commenting them but the BLE service stops

Edit:

But you have really long delays in send_data_to_biboA(), what interrupt priority does nus_data_handler() run? Have you tried to remove the delays?

Can you comment out the init of logging (or move it to main())?

//APP_ERROR_CHECK(NRF_LOG_INIT(NULL));
//NRF_LOG_DEFAULT_BACKENDS_INIT();

Have you checked if you have an assert (run to app_error_fault_handler())?

No this did not solve the problem and the Bluetooth advertising is stopped as soon as this function is called send_data_to_biboA(); and the whole process is stopped

I suspect it is an interrupt priority issue, for instance that nus_data_handler() have equal or higher priority than spi_event_handler(), this will cause the spi_event_handler() to not be able to update the spi_xfer_done flag. You can try to change SPI_DEFAULT_CONFIG_IRQ_PRIORITY to 3 to see if that solves it.
