Button normal press and long press detect

[Sunil vignesh]

Hi,

I need some clarification about how to differentiate the normal press and long press detect for a single button to assign awake and sleep mode.

I am using nRF52832 SDK15.3 in segger embedded studio .

Is there any predefined code for sleep and awake system?

Hi,

Please see my answer in this thread for some suggestions on how you can differentiate between long and short button presses. What kind of sleep mode did you have in mind, system OFF or System ON mode?

Hi Vidar,

i didn't receive any link please resend it.

when long press the button  system get into sleep mode or (system OFF)

when the press the button with normal delay system get ON mode

is it possible.

any code reference is there?

Sorry, here's the link I was referring to: https://devzone.nordicsemi.com/f/nordic-q-a/43506/how-to-use-bsp_button_action_push-and-bsp_button_action_long_push-on-the-same-button-with-two-different-functions 

You don't need to a button to enter System ON mode, just let the program return to your main loop. You can, however,  use a "long" button press to make the program enter System OFF.

Hi, Vidar

i have used the code when i press the button 1 . short press arrived

but during long press no log came it shows only short press ..?!

and one more thing

as per ble_app_uart

uses BSP_BLE_ module  link .  here

as it is but i need is

current status         button          action              event

connected                 1              long push            BSP_EVENT_SLEEP

not connected          1              long push            BSP_EVENT_SLEEP

sleep                         1              long push            BSP_EVENT_WAKEUP

shall we change it like this???

[Vidar Berg]

The implementations include code for using both BSP and button handling library, see #ifdefs. I have tested it with SDK 15.2.0

Vidar, Now i didn't change anything

freshly opened ble_app_uart  (from sdk15.3)

In bsp_btn_ble.c  file

static uint32_t connection_buttons_configure()
{
    uint32_t err_code;

    err_code = bsp_event_to_button_action_assign(BTN_ID_SLEEP,
                                                 BTN_ACTION_SLEEP,
                                                 BSP_EVENT_DEFAULT);
    RETURN_ON_ERROR_NOT_INVALID_PARAM(err_code);

    err_code = bsp_event_to_button_action_assign(BTN_ID_WHITELIST_OFF,
                                                 BTN_ACTION_WHITELIST_OFF,
                                                 BSP_EVENT_WHITELIST_OFF);
    RETURN_ON_ERROR_NOT_INVALID_PARAM(err_code);


    err_code = bsp_event_to_button_action_assign(BTN_ID_DISCONNECT,
                                                 BTN_ACTION_DISCONNECT,
                                                 BSP_EVENT_DISCONNECT);
    RETURN_ON_ERROR_NOT_INVALID_PARAM(err_code);

    return NRF_SUCCESS;
}

is changed to

static uint32_t connection_buttons_configure()
{
    uint32_t err_code;

    err_code = bsp_event_to_button_action_assign(BTN_ID_SLEEP,
                                                 BTN_ACTION_SLEEP,
                                                 BSP_EVENT_DEFAULT);
    RETURN_ON_ERROR_NOT_INVALID_PARAM(err_code);

    err_code = bsp_event_to_button_action_assign(BTN_ID_WHITELIST_OFF,
                                                 BTN_ACTION_WHITELIST_OFF,
                                                 BSP_EVENT_WHITELIST_OFF);
    RETURN_ON_ERROR_NOT_INVALID_PARAM(err_code);


    err_code = bsp_event_to_button_action_assign(BTN_ID_DISCONNECT,
                                                 BTN_ACTION_DISCONNECT,
                                                 BSP_EVENT_SLEEP);
    RETURN_ON_ERROR_NOT_INVALID_PARAM(err_code);

    return NRF_SUCCESS;
}

getting restarted

Coming back to your code which you given from the link

i changed the value as

#define USE_BSP 1

and

void bsp_event_handler(bsp_event_t event)
{
    uint32_t err_code;
    switch (event)
    {
        case BT0_SHORT_PUSH:
            NRF_LOG_INFO("Short button press");
            printf("\r\n Short button press.\r\n");
		 
            break;
        
        case BT0_LONG_PUSH:
            NRF_LOG_INFO("Long button press");
		printf("\r\n Long button press.\r\n");	 
			sleep_mode_enter(); 
            break;

        default:
            break;
    }
}

just called sleep_mode_enter(); in the LONG_PUSH event

system getting  restarted  not when to off state

Vidar Are you there?

[Vidar Berg]

It either means that the chip does not enter sleep because it is in debug interface mode, or that you have a pin that wakes it up again as soon as it goes to sleep. In other words, you need to test this without having the debugger attached, and go over your pin configurations.
