SOFTDEVICE_PRESENT

[lydie]

Hi, 

I use sdk15.3, with segger embedded and with PCA10040.

I try to combine two programs to display the actual date on an lcd screen:

- one using Bluetooth to have the actual date (ble_app_proximity)

- one using gfx library to display something on the screen with st7735

I have a problem with SOFTDEVICE_PRESENT, because it isn't defined in the program using gfx, so nrf_error.h looks like this:

And it's defined in the program using Bluetooth, so nrf_error.h looks like this:

When I built my combined program, the error is: 'NRF_SUCCESS' undeclared (first use in this function); did you mean 'EXIT_SUCCESS'? 

It's normal because the compiler ignores nrf_error.h

So I don't know what to do. In fact, I don't know what is SOFTDEVICE_PRESENT real use, where is defined, and if I need to define it or not.

Can I get some help to get a clearer picture?

Thanks,

Lydie

When you combine 2 (or more) examples, you need to combine the sdk_config.h settings.

Sadly, there is no tool to do this, and Nordic make it unnecessarily difficult by not keeping the example sdk_config.h files consistent.

See: devzone.nordicsemi.com/.../178402

So it's a matter of manually, laboriously, tediously, going through the two  sdk_config.h files.

I recommend Keil uVision for viewing/editing the sdk_config.h files - the free version will do.

See: https://devzone.nordicsemi.com/f/nordic-q-a/48768/combining-2-examples/193667#193667 - there's a uVision project there to help you.

I now understand why the timeout error I was receiving was due to an invalid parameter. I appreciate you explaining it to me. Prior to now, I was unaware of the cause, but I now understand it.
