Hi

What most people have trouble with is forgetting to enable something in the sdk_config.h file. You have to go through the sdk_config.h file of a uart example, and make sure that all functions enabled there are also enabled in your projects sdk_config file, as in setting all functions that are set to 1 in the example sdk_config to 1 in your project as well. If there are some functions enabled in the example file that is not at all in your project, you will have to copy/paste those. 

Best regards,

Simon

Thanks.

We have already enabled all functions accordingly in config and no error is shown.

NRF_LOG_DEFAULT_BACKENDS_INIT() creates problem.

when we comment it only uart works but when we uncomment it nothing works.

We want both UART and SPI to work .

Any help would be highly appreciated.

Best Regards,
