Hi,

I maybe not the best to answer question on nRF8001 and Arduino. But as far as I know, the nRF8001 has the RDYN pin to interrupt the MCU when it has data want to transmit (events), it's mentioned here :

"If BLE Shield has data to transmit to master, it will put the RDYN to low to indicate master, even though master havn't requested data and REQN is idle. If master detectes a low level condition on RDYN, it will put REQN to low and generate the clock to read out the data.After reading out the data, both REQN and RDYN will be put to high.Note that REQN is controlled by master while RDYN is controlled by BLE Shield."

Most likely you will have an interrupt when there is a write event from the central device.
