Hi Lal,

I feel like I hardly help at all. Glad you got it working!

Enjoy coding!

Hi Hieu, thank you very much for your quick reply.

GOT it solved !!!

The path to sdk_config.h was pointing to "nRF5_SDK_17.1.0_ddde560\config\nrf52840\config" not to the example specific "examples\ble_peripheral\ble_app_uart\pca10056\s140\config"

Thanks again and best regards,

Lal

Hi Lal,

[quote user="maveli"]a. is there somewhere other than sdk_config.h, the preprocessor UART_ENABLED ?[/quote]

No, it should only be defined there. You can search the entire SDK file content to confirm this.

[quote user="maveli"]b. If not why apply_old_config.h doesn't recognize UART_ENABLED as set even if it is in sdk_config.h?[/quote]

Is there a symptom that makes you think so? If it is the IDE UI, sometimes it just doesn't unravel the preprocessor correctly.

[quote user="maveli"]c. Very similarly why would NRFX_CHECK(NRFX_UART_ENABLED) is FALSE even though NRFX_UART_ENABLED is 1 in sdk_config.h?[/quote]

apply_old_config.h can set it to 0 depends on other configurations. Are you absolutely sure you didn't change anything other than paths in the project file?

Hieu

Hi Hieu,

thanks for your reply.

Yes I did a clean build and also tried with a clean falsh. No difference.

ble_app_uart works fine, when I try to compile it from the examples.

As I mentioned above this build error is coming up when building at different location ( with correct paths); other examples are working fine with this location.

To keep the doubt simple:

a. is there somewhere other than sdk_config.h, the preprocessor UART_ENABLED ?

b. If not why apply_old_config.h doesn't recognize UART_ENABLED as set even if it is in sdk_config.h?

c. Very similarly why would NRFX_CHECK(NRFX_UART_ENABLED) is FALSE even though NRFX_UART_ENABLED is 1 in sdk_config.h?

I will be very thankful for your answers.

Bests,

Lal

Hi Lal,

Have you cleaned and rebuilded your project after moving from SES 6.20 to 5.60?

If not, I would recommend you start with an unmodified ble_app_uart example, apply your necessary location change configurations, and build from a clean state with SES v5.60.

Another thing to check is, have you cleaned the flash memory before flashing your sample? If not, please do that.

I use the ble_app_uart fairly regularly and it does not require any modification like you are doing.

The threads you linked are also for older versions of the SDK. If I remember correctly, the legacy driver integration, for example, has changed quite much between v15.0.0 and v17.1.0, so the information might not be applicable. I still suspect the "mixed compiler build" to be the issue.

Best regards,

Hieu
