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.

About the active line: This can be enabled and can be used to wake up the MCU prior to a connection event in case you would like to prepare some data to send in the event. Note that there is some restriction to the use as it will be automatically disabled if the connection/advertisement interval is shorter than 30ms.
