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)

This might not be the problem in your case but it is best if you check for error returned when you call spi_master_send_recv

[muhkuhns]

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?

[muhkuhns]

I had

spi_master_evt_handler_reg(SPI_MASTER_0, spi_master_event_handler);

inside

spi_master_init()

(found this somewhere as an working example..) I moved it to main() and now the Transfer Completed is called!
