I'd like to add a peripheral device to the example code.

[yun sung hyuk]

Hello, I am
I'm a Beginner at developing NRF 51822.

My Development Environment

sdk : 12.3

IDE: KEIL v5

SoftDevices : s130

I am developing using the example of 'ble_app_uart' of 'sdk 12.3'.

I want to add a peripheral device to the example code, but there was an error, so I'm asking you a question.

I will attach the problem as shown in the picture.

First, we added a timer example to the 'ble_app_uart' example.
Of course, we also modified the header and the included path options for c/c++.

 

However, during the build process, you will still receive an error stating that the symbol could not be found.

Please let me know if I added anything wrong.

Thank you for reading it.

You also need to enable the timer in the sdk_config.h file.

It should look like this:

#ifndef APP_TIMER_ENABLED
#define APP_TIMER_ENABLED 0
#endif

Just set that to '1' instead of '0'

Also, TIMER0 and TIMER1 should be set to '1'. Or more can be enabled if you need them for whatever reason.

#ifndef TIMER0_ENABLED
#define TIMER0_ENABLED 0
#endif

// <q> TIMER1_ENABLED  - Enable TIMER1 instance
 

#ifndef TIMER1_ENABLED
#define TIMER1_ENABLED 0
#endif

I solved it.
I'm writing because I think there might be someone who makes a rudimentary mistake like me.

I've added a header file.

Additionally, the error occurred by building the c-file without adding it.
