Hi,
I've been trying to get the button events from the nrf52832 where FreeRTOS is enabled.
https://gist.github.com/gpgabriel/f070e39f335da8579e9a577b44109237
The 2 function are from `ble_app_blinky` example. When I call `buttons_init` in main, I get:
<error> app: ERROR 8 [NRF_ERROR_INVALID_STATE] at ..//main.c:813
I spent a few hours trying to debug this and I think I found out why I get this but I'm not sure how to solve it.
`app_button_init` will call `app_timer_create` from `app_timer_freertos.c` which checks `pinfo->osHandle` and as it won't be NULL, it returns `NRF_ERROR_INVALID_STATE`.
I think `pinfo->osHandle` won't be null because in `app_button.c`, the same `m_detection_delay_timer_id` is also used in `gpiote_event_handler`.
I'm using nrf52 SDK 14.2. It works fine without FreeRTOS.
I'm not sure if I'm right with my explanation, maybe I'm missing something.

EDIT: I was wrong, the problem is that the osHandle is not empty (not sure why), it doesn't have to do with `m_detection_delay_timer_id`
EDIT2: I'm really confused on how the APP_TIMER_DEF(timer_id) variable can be casted to a 'app_timer_info_t *'
