RE: Interrupts on SoftDevice functioning

Hi,

Great questions, trying to answer those I found that another output pin controlling the reset of the external chip was toggling with the bsp module (I couldn't find exactly how, but the influence is there). So changing this pin solve my problem.Thanks!

Hi,

This should work even if you connect to a BLE device.

What pin number is INT0_PIN? Is this pin maybe used somewhere else in your code? (e.g. by bsp / app_button lib or similar)

How do you define in_config? something like this ?

nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_TOGGLE(true);
in_config.pull = NRF_GPIO_PIN_PULLUP;

or maybe GPIOTE_CONFIG_IN_SENSE_HITOLO() ?

What service is this?

Do you call app_button_disable() or nrf_drv_gpiote_in_event_disable() somewhere in your code ?

[quote user=""]I can see that before the service enables, the interrupt never fires because I placed a counter in the event handler.[/quote]

Are you sure that the pin is actually toggling or goes from high to low? Have you scooped the pin?
