Interrupt Pin on nrf8001 to wake MCU

[Nishant Sood]

I need to wake my uC from sleep when the nrf8001 gets in connected mode and for that I need to supply an external interrupt on hardware interrupts on the MCU.

Will active pin full fill my need?

Hi,

You should use the RDYN pin. This will be lowered by the MCU whenever the nRF8001 has an event ready.

BUT I'm not able to effectively wakeup from sleep, I'm having the RDYN mapped to pin 2 of my atmega328p which is the lowest and first most hardware interrupt trigger still the chip won't wakeup efficiently. where I'm wrong here?
