app_button_init() and app_button_enable() returns NRF_SUCCESS. But event handler of app_button isn't called.
log messages of nRF52832 device is as follows.
00> <debug> app: app_button_init() errCode=0x0
00> <debug> app: app_button_enable() errCode=0x0
I am using the Softdevice.
Hi.
Can you share your project?

Jared
I have shared button.c and gripe.c. And I call gpioe initialize and button initialize function in main(). Do you have suggested examples for app_button?
Hi,
It would be great if I could reproduce this at my end. Which is why I ask for your project. Could you at least share a minimal example that reproduces the issue?
For example, I need to verify that the LFCLK is started correctly and that the program never enters the callback handler of the app module.

Jared
Could you suggest example code for me to add app_button? Then I can share whole project source code to you.
You can use ble_app_blinky example code to reproduce this issue.
You can use ble_app_blinky example code to reproduce this issue.
Hi,
Not sure how the ble_app_blinky example reproduces your issue. Can you share your project so I could reproduce your results on my side? I can make the case private first if you prefer it?

Jared
Hi
Jared is currently unavailable, and I will help you out in the mean time.
Thanks for sharing the code.
I see the code contains defines for running it on either a custom board or a DK. Do you see the same issue on the DK, or only on the custom board?
Are you sure the button is connected the same way on the custom board as it is on the DK?
The config enables pull up on the button input, which means the pin must be disconnected when the button is released, and pulled to ground when the button is pressed.
Have you tried to connect a scope or multimeter to the button input to verify that it has the expected voltage when the button is pressed and released?
Best regards
Torbjørn
I don't have DK. I use GPIOTE to detect button event. It can capture NRF_GPIOTE_POLARITY_TOGGLE event.
