Timer setting problem

[cemalb]

I have created file timer_init.h / c. I make the timer settings in this file and include it in main.c.
I create the timers in the timers_init () function. However, the 2 timers I show below do not stop when I call app_timer_stop ().
But if I define these timers in main.c, it works fine. What could be the problem?

Hi,

Use the debugger and debug your application:

1. Does the program actually enter and return from app_timer_stop() without returning any errors?
2. Do you get any relevant warnings during compile time?
3. Have you included your files correctly?

Answering these questions would be a good start for finding the root cause

Hi,

1-)When using app_timer_stop () I was not returning err_code. After you told me, I edited my code like this:

err_code = app_timer_stop(m_open_door_hash_value_timer_id); /* Stop open door hash value timer. */
APP_ERROR_CHECK(err_code);

err_code = app_timer_stop(m_open_door_timer_id); /* Stop open door timer. */
APP_ERROR_CHECK(err_code);

After doing so, the program started going to NRF_BREAKPOINT_COND. But I don't know how to read the error code.

2-)During compilation I get a warning like this. I guess it has nothing to do with this problem.

3-) I don't think there is a problem in this part.

If I'm not mistaken, the code NRF_ERROR_INVALID_STATE is being returned. 

I created the variable uint32_t code1,code2. 

code1 = app_timer_stop (m_open_door_hash_value_timer_id);

code2 = app_timer_stop (m_open_door_timer_id);

watched the variables. both have values 0x00000008.

Hi,

0x08 Is indeed a NRF_ERROR_INVALID STATE. The documentation states:

NRF_ERROR_INVALID_STATE

If the application timer module has not been initialized or the timer has not been created.

Next step would therefore be to verify that the application timer module is initialized and created in your project before you call app_timer_stop().

hi,

There is no problem when creating a timer with app_timer_create (). they all return the value 0x00. I guess that means NRF_SUCCESS.

[Jared]

Hi.

Have you made sure that the timer has been initialized and started before you call app_timer_stop() in your code?

Yes, I'm sure
