BUTTON_1 release issue

[good_night]

I expanded the button events based on example ble_peripheral ble_app_hrs by

bsp_event_to_button_action_assign (0, BSP_BUTTON_ACTION_RELEASE, BSP_EVENT_KEY_0_RELEASE);
bsp_event_to_button_action_assign (1, BSP_BUTTON_ACTION_RELEASE, BSP_EVENT_KEY_1_RELEASE);
bsp_event_to_button_action_assign (2, BSP_BUTTON_ACTION_RELEASE, BSP_EVENT_KEY_2_RELEASE);
bsp_event_to_button_action_assign (3, BSP_BUTTON_ACTION_RELEASE, BSP_EVENT_KEY_3_RELEASE);

and everything works fine (button press and button release events for all 4 buttons) till I connect the device:

Then button_1 release event (in code: BSP_EVENT_KEY_0_RELEASE) does not appear further more - I do not receive the event also after disconnecting.

Any hint what prevents this event?

Hi.

So being in a connection prevents you from getting events from the button release? That sounds strange.

Could you add information about what device, SDK version, SD version etc. you are working with?

2 devices: rF52840 DK and costomized HW with SDK 16.0

all the same behaviour: button 1 release is not working, other button releases (2 to 4) are working well.

btw.: I have disabled sleep_mode_enter() in on_adv_evt(case BLE_ADV_EVT_IDLE) and in bsp_event_handler(case BSP_EVENT_SLEEP) because I need no power saving so far.
Could it be the bonding to wake the device : remark for buttons_leds_init() - If yes, how to disable it?

Hi Joakim,

further investigation with 5 active buttons (code for pca10056.h shown in code box)

#define BUTTONS_NUMBER 5  // 4

//#define BUTTON_1       11
#define BUTTON_1       NRF_GPIO_PIN_MAP(1,07)  // dummy
#define BUTTON_2       11
#define BUTTON_3       12
#define BUTTON_4       24
#define BUTTON_5       25
#define BUTTON_PULL    NRF_GPIO_PIN_PULLUP

shows that a workaround would be possible with avoid using button_1 (here set as a dummy port).

All events for BUTTON_2 to BUTTON_5 are working well now.

The missbehaviour keeps linked to BUTTON_1 which seems to have a special function.

How to disable this special function?

Thank you for all hints & KR

Peter

P.S.: sdk_config.h needs to be changed in one line:

// <o> GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS - Number of lower power input pins 
#ifndef GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS
#define GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS 5 // 4 <---
#endif

Have you made sure that there isn't a reference to BUTTON_1 elsewhere in your project that might be keeping you from getting the events after connection?

Br,
Joakim

Well, that's exactly the question. Because it is Nordic's example, I do not know: I have to return that question to the Nordic developers.

As I wrote before I extended the ble_app_hrs_pca10056_s140 example with the BSP_BUTTON_ACTION_RELEASE functions - no further reference to BUTTON_1!

[Joakim Jakobsen]

I see. 

You can see what the button assignments for the native example here: 
BSP BLE Button Assignments 

In your example, you still have the original events in your bsp event handler. I only have your main.c file, so I don't know what other changes you have made. 

You can see the functions for configuring the buttons in the bsp_btn_ble.c file. Both for connection and advertising.

Hi Joakim,

thank you for pointing to file bsp_btn_ble.c!

I modified the lines

//2020-06-28 pam wakeup and sleep functions disabled
//by assigning them to button #5 that is not configured
#define BTN_ID_WAKEUP             5 //0  /**< ID of button used to wake up the application. */
#define BTN_ID_SLEEP              5 //0  /**< ID of button used to put the application into sleep mode. */
#define BTN_ID_DISCONNECT         5 //0  /**< ID of button used to gracefully terminate a connection on long press. */
#define BTN_ID_WAKEUP_BOND_DELETE 5 //1  /**< ID of button used to wake up the application and delete all bonding information. */
#define BTN_ID_WHITELIST_OFF      5 //1  /**< ID of button used to turn off usage of the whitelist. */

#define BTN_ACTION_SLEEP          BSP_BUTTON_ACTION_LONG_PUSH //BSP_BUTTON_ACTION_RELEASE    /**< Button action used to put the application into sleep mode. */
#define BTN_ACTION_DISCONNECT     BSP_BUTTON_ACTION_LONG_PUSH  /**< Button action used to gracefully terminate a connection on long press. */
#define BTN_ACTION_WHITELIST_OFF  BSP_BUTTON_ACTION_LONG_PUSH  /**< Button action used to turn off usage of the whitelist. */

to disable all the configured functions for wakeup, sleep, etc. and now it works!
