SPI_MASTER_EVT_TRANSFER_COMPLETED never reached in ble_UART example

[muhkuhns]

main.c

I am trying to talk to this sensor: www.meas-spec.com/.../MS5803-05BA.aspx via SPI... it quite seems to work as I get expected responses to commands but as the title says "SPI_MASTER_EVT_TRANSFER_COMPLETED" is never called. And I can't figure out why. Also debugging just stops at an certain line without giving any error (at least I can't see any)

Like this:

uint32_t err_code = spi_master_send_recv(SPI_MASTER_HW, p_tx_data, len, p_rx_data, len);
    APP_ERROR_CHECK(err_code);

? Where/How will I see when there was an Error?
