Timer setting problem

Then I'm not sure how you can get a NRF_ERROR_INVALID_STATE..

Could you share a minimal example that can run on the nRF52DK and will reproduce the issue?

Yes, I'm sure

Hi.

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

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.

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().

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,

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.

Hi,

Use the debugger and debug your application:

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

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