Problem with interrupt

Anonymous · ‎Aug 07, 2014

In SDK 2.1.0 in hello_client app I noticed that interrupt handler is called always twice on very event. Why is that ?

Hello_sensor app from the same SDK does not have this issue.

The button in hello_client is configured additionally with:

GPIO_BOTHEDGE_INT

and as a result the interrupt handler is called twice when the button is pressed and twice when released.

In hello_client_create(), remove calls to bleprofile_Init() and bleprofile_GPIOInit(). blecen_Create() called later invokes these. This will cause two callbacks (both pointing to the same callback function) to be registered with the GPIO driver for interrupts on the 'button' GPIO.
