Question about using NFC to pair example

[MANGO]

Hi, I am about to purchase PCA10040 V1.1.0.

I heard that one has the latest chip revision nRF52. (ref. link)

I'm very excited to start with the new feature in nRF52; the NFC feature.

However, it is my first try with it and I have some questions.

The reason for posting this is that I haven't found articles about NFC in Nordic's blog or tutorial section.

1. I have watched this demo video (How to use NFC to pair your devices).

Is there a similar example in the latest Nordic's SDK?

2. In that demo video, it asked about pairing when tagging the phone to the NFC antenna.

Was that demo using OOB (out-of-band) pairing?

If not, is there an OOB pairing example in the latest Nordic's SDK?

-Best Regards, Mango

1. Yes.

2. I believe it was OOB pairing with the Windows Phone, but not with the Android phone. As far as I know Android does not support OOB pairing yet, but some Windows Phones do.

The example above will do OOB pairing if the central device supports it, if not, it will do Just Works pairing.

Hi, Petter. Then I should check out whether Android supports OOB or not in detail.

About "The example above will do OOB pairing if the central device supports it, if not, it will do Just Works pairing.",

do you mean that if I edit the example code (Experimental: Heart Rate Application with BLE pairing using NFC),

then the code can distinguish whether the central device supports OOB or not?

Similarly, can the central device tell whether the peripheral is trying an OOB pairing or not?

[Petter Myhre]

See this MSC. If the central supports OOB or not is included in the BLE_GAP_EVT_SEC_PARAMS_REQUEST event. The peripheral will tell the central that it supports OOB by setting the OOB bit in sd_ble_gap_sec_params_reply().
