nrf8001 interrupt

[Hani Abidi]

I am using an Arduino and NRF8001 break out board from Adafruit. I am using the UART profile (adafruit sample code) to send data between mobile phone and Arduino. However, I don't want my arduino to look for serial data at all times.

I am thinking their should be a way that NRF8001 can send an interrupt signal to Arduino to wakeup, if data is available?

Is that a possibility? I couldn't figure out. I have came across /RDY terminal, but it doesn't seem to be able to do the above.

Thanks Hani

You should be able to use the RDYN line as an interrupt for the Arduino . The nRF8001 SDK for Arduino does support an interrupt mode of operation using the settings in the lib_aci_init().

aci_state.aci_pins.interface_is_interrupt and the aci_state.aci_pins.interrupt_number.
