Most likely like this: buttons_leds_init() -> bsp_init() - > app_button_init() -> nrf_drv_gpiote_init().

I am using the ble-peripheral/Template example.It is working without calling the nrf_derv_gpiote_init() funtion.Also the bsp_button_3 is giving the problem.I replaced both with port1.01 and port p0.02.And now its working .Thanks for ur help but i still cannot find where i called the init funtion.

Please search your entire project for other functions calling nrf_drv_gpiote_init(). If GPIOTE is already initialized, you should be able to use it without calling the init function.

i tried using another pin as input instead of button 3 but i am getting same error. please help i can confirm that

nrf_drv_gpiote_init() is causing the error.but i dont know how to resolve it.

There are (at least) two functions inside gpio_init() that can return error code 8 (NRF_ERROR_INVALID_STATE); nrf_drv_gpiote_init() and nrf_drv_gpiote_in_init(). Please check which function is returning the error. If it is nrf_drv_gpiote_init that returns the error, please search your project for other functions/libraries that are using the GPIOTE driver. If nrf_drv_gpiote_in_init is returning this error, please make sure this pin is not for anything else in your application.

I followed the link and could send data to the nrfconnect app.But once i added the interrupt funtion to count the number of button press(pulses) the code was not working I am getting an errror 8[NRF_ERROR_INVALID_STATE] it happens when i add the gpio_init(); funtion here is the code

Hi,

You can create a custom service that will send a notification on every variable change, or every 5 seconds if you want (controlled by a timer). We have some tutorials on creating custom services/characteristics here on DevZone, but they are a bit outdated. This GitHub page contains an updated tutorial that support SDK 14 and nRF52840.

For incrementing the variable using buttons, you can use the app_button library. This page describe how this can be done. Note that there is a bug in the SDK that that makes GPIOs on Port 1 on nRF52840 not work with the Button handler library.

Best regards,

Jørgen
