BLE_APP_UART_PCA10010 change doesn´t work

[simon1516]

Hi,

I´m trying to change the "BLE_APP_UART_PCA10010" example, main.c file.

I would like to delete following functions, because I don´t need UART in my project:

void uart_event_handle()

static void uart_init(void)

But when I comment out "uart_init();" in main function and flash this to nRF52833, it doesn´t work. The BLE device can´t be found by nRF connect app. I can´t find any relation between this UART functionality and the BLE stack.

Can you give me more information, whats gonna be wrong?

Thanks in advance

Hi,

Ah, there is one other detail that causes problems with the RTT viewer in SES. You also need to set NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED to 0 in sdk_config.h. In that case, and with the other changes you did, you should see the RTT log in the Debug terminal window in SES. Can you try that?

Hi,

the "NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED " was already set to 1 (I comment out the if-instruction additionally now, s. screenshot).

If I press "debug and build", the pointer stops when it reaches "log_init" function in main.c (s. screenshot attached). But in Debug terminal window nothing happened. Is there something else I can try?

Sorry, this was a typo on my part. NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED should be set to 0. (I will update my previous reply as well.) With this, you should see errors logged.

And regarding the original issue, you must make sure to remove all calls that use the physical UART (as described). You will get errors when you use the physical UART without calling the init function. (For instance, calls to app_uart_put() or app_uart_get() will return an error since you are trying to use a library and driver that hs not been initialized).

hmm, unfortunaly I can´t see anything on debug terminal. I have enabled both options in sdk_config.h with CMSIS configuration wizard as shown in screenshot attached.

After setting "NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED" to zero, nothing happened. The debug terminal is empty, allthough I press the play button. The result is the same like posted above :-(

I also have this issue, I tried all the SDK_CONFIG shorts but couldn't make it work. I then tried a SEGGER_RTT_LOG (can't remember the exact name) call directly and the message appeared, so it does look like there's something up with the macro or whatever translates the NRF_LOG calls over.

It's not a big deal to me as I prefer breakpoints. :)
