the adafruit BLE sensor, which I would use in my home automation software (homeseer) to trigger events.. Not sure if I have all the right things lined up.

Hi Tom,
That module i believe will only operate as "peripheral" role. I think if you want to connect it to an arduino which will then "report" the presence of your Iphone/iwatch then you need to have a BLE module running as a "central" role..

Alternatively...you could use your iphone to detect an "ibeacon" and the iphone would report back the presence over its data connection to your homeseer ( i dont know how exactly as i dont use iphone nor homeseer.. but it would be easy with android+vera)

thanks Greg,
ok so I been reading...it seems you can turn your iphone into a iBeacon, but then how do you get iBeacon detected by arduino

Hi Greg,
Hoping the iphone or future apple watch would be "sensed" by the adafruit BLE sensor, which I would use in my home automation software (homeseer) to trigger events.. Not sure if I have all the right things lined up.

I'm a complete newbie so please pardon my ignorance and questions?

Goal: build a proximity/presence sensor with Bluetooth Low Energy (BLE 4.0) - nRF8001 Breakout.

So I'm trying to figure out what hardware I need.

1. Could I use Arduino ATmega2560
2. And http://www.adafruit.com/product/1697
   3.Ethernet Shield:for the ATmega2560 could I use:
   Ethernet Shield W5100 For Arduino Main Board 2009
   or
   Ethernet Shield WizNet W5100 R3link text
   or
   TOP Mini W5100 link text

Is there anything else I'm missing- cables, power supply ??

Thank you for your help.
Tom
