Hey Kenneth,

the CMSIS tool is very helpful. I forgot 3 ble libraries. Now I can build my program but I get an error in uart_init in part app_uart_fifo_init (code below).

Error code:

<error> app: ERROR 8 [NRF_ERROR_INVALID_STATE]

lines:

static void uart_init(void)
{
    ...

    APP_UART_FIFO_INIT(&comm_params,
                       UART_RX_BUF_SIZE,
                       UART_TX_BUF_SIZE,
                       uart_event_handle,
                       APP_IRQ_PRIORITY_LOWEST,
                       err_code);
    APP_ERROR_CHECK(err_code);
}

According this thread this error could mean that the UART driver is already initialized. What do you think?

If I comment out this lines, I get another error at this line in main:

int main(void)
{
    ...
    
    err_code = ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST);
    APP_ERROR_CHECK(err_code);
    
    ...
}

The error code is:

<error> app: ERROR 7 [NRF_ERROR_INVALID_PARAM]

Unfortunately I am not aware of any easy overview, however I believe you should find a rather complete sdk_config.h file in [SDK root]\config\nRF52832

Typically you need to refer an example that use a specific software module for example configuration. Also you may find the documentation for the SDK config file useful in general:

And I have another issue:

It's not clear which flags in sdk_config.h should be 1 and which flags should be 0. Hundreds, even thousands of lines may differ. Some flags are only defined in certain sdk_config.h files. Also I don't know which header files are needed. Is there a documentation or something else which explains for e.g. "peer manager" what should be changed in config file and which headers should be included?

Because how to include headers, paths and c-files and how to change config file is the easiest thing of all... But not to choose the right h-files and config flags.

I hope, you or someone else can help me.

Best regards

Christoph

Hey Kenneth,

thank you for your advice. I will look at your online tutorial and your ses document. So do you think I only added and imported the files not correct?

Best regards,

Christoph

Hi,

Maybe the online tutorial on importing files and drivers can be useful?

Also http://infocenter.nordicsemi.com/pdf/getting_started_ses.pdf chapter 8.6 Adding files can be useful.

Best regards,
