This is an older device but there are no power consumption issues with it, so it should work as expected.

Thanks for getting back. I used the setup in figure 30 with a 10R resistor.

Have you measured the current consumtion of the nRF8001 alone and not the ATMega328 as well, Perhaps you can add some information on how you did the current measurements. You can also look at our application note for measuring current consumption here, see section 8 on current consumption .

Nordic "WelloWorld" sketch is used unchanged. Olimex board has 100k pullups on the reset and REQN lines (so max 2x 33uA from that?).Schematic

If I look at the current over a 100R resistor in the power line, I see about 6mA every 50ms during adverstising and same current every 20ms when connected to the UART App. Is this correct?

Thanks for your comment. The markings are: NRF C; 8001; 1147AA The device version ACI gives back: 1

Can you give the chip markings on top of the IC ? also provide the results of the GetDeviceVersion ACI command. i.e. lib_aci_device_version()

This could be related to floating pins on the interface between the ATMEGA and the nRF8001 while the nRF8001 is in power down in between connection events. Are you making sure that the pins are set to a defined level from the ATMEGA?
