Is it possible to use the UART without the Soft Device?

[Eliot Stock]

There are some include dependencies that go like this:

app_uart.h -> app_util.h -> app_error.h -> nrf_error.h

and nrf_error.h is under Include/s110.

In order to debug some stuff happening with my UART peripherals, I'd like to do a build with my UART code included but the Soft Device not included, so I can use the extra memory for writing a log of my UART conversation.

Looks like this isn't going to be possible?

The softdevice is not needed to use the UART peripheral. You should be able to get along just fine with nrf51.h and nrf51_bitfields.h.

Thanks again. I now seem to be stuck at the __WFI() call in this loop when reading from the UART:

do
{
    err_code = app_uart_get(&ch);
    
    if (NRF_ERROR_NOT_FOUND == err_code)
    {

#ifdef USE_SOFTDEVICE sd_app_evt_wait(); #else __WFI(); #endif } else if (NRF_SUCCESS == err_code) { response[i++] = ch; } else { APP_ERROR_CHECK(err_code); }

    ended = gsm_response_ended((char *)response);
}
while (!ended);

Also the timer that should make gsm_response_ended() return true eventually even if the peripheral stays quiet is never getting its timeout handler called. Any ideas?
