Adding UART support to app_template requires include app_uart.c

[Ivan Herrera]

I've been trying to add UART support from the uart example to the ble_app_template example. I've enabled all the required drivers and options in sdk_config.h and included the same header files as in the other example but I'm receiving these errors for the uart functions I'm using: "undefined reference to app_uart_get" and "undefined reference to "app_uart_init".

Though when I also include app_uart.c alongside app_uart.h, the error fades away. Is there a simple explanation for this? I'm using SEGGER Embedded studio and have added "../../../../../../components/libraries/uart" in the user includes. I'm using SDK 15.3 on OSX, alongside an nRF52840 PCA10056.

Hi,

You will need to manually add all source (.c files) to your project for api you want to use.

Best regards,

Hi Kenneth, 

I have a follow-up question. In the example that source file isn't actually included. How come? eg. the pheripheral UART example

EDIT: Nevermind, I finally see now... Sorry I haven't used SES in a while. Thanks!!
