Can a nRF8001 or nRF8002 do this? (Proximity)

I have started using the Eval Board and following examples outlined in the SDK. How do I modify the Proximity Demo to recognize devices only when they are in close proximity, and perform an action that I choose? And how would I differentiate between phones that are near by?

I have looked into the code and I may be in over my head for the time being. Are there people that can write the code to accomplish the tasks I need? I am trying to learn, but it seems a bit complex at the moment.

The documentation for the SDK is here https://devzone.nordicsemi.com/documentation/nrf51/5.2.0/html/index.html , you need to wait for your Evaluation kit to get full access.

Ok great. I am going to order the nRF51822 Eval kit and have a go at it. Researching this online, I am seeing reference to a nRF51822-EK User Guide which I cannot find on the Nordic site. Is there a special location for this? Would like to take a look while I wait for the hardware to arrive.

Also I guess I have to wait for the hardware and key/serial# before I have access to the SDK?

The nRF8002 is constrained only to one phone. You can choose to use the nRF51822, which should be able to provide the this functionality on a single chip. To detect multiple users using the nRF8001, you would cycle through your list of users to see which of them is present. The detection would take a few seconds. . You can use the ble_HID_keyboard_2_bonds_template to see the usage with multiple users.

Thanks for the info. Someone elsewhere mentioned that the 8001 will not be able to differentiate between multiple phones though. Is this true? I need to be able to detect multiple phones but connect to only one at a time, and execute a unique action for each phone that connects.

If I cannot do that, then maybe another idea is have multiple 8001s which are only paired with one device and they act independently?

Is the 8002 more suitable for my needs? I cannot determine which is best for me.

This is definitely possible using nRF8001 and nRF8002, see the ble_proximity_template in our github Arduino code sample for nRF8001. ( github.com/.../ble-sdk-arduino ) See the code for the text "Do more stuff here. when your phone is detected".

Would a simple Arduino facilitate this? Yes

If you are using the nRF8002, it can activate pins when it has detected a phone can that can be hooked to the action that you want.
