nRF52 NFC: Connecting Bluetooth without pairing?

[puz_md]

Hi, I want to connect to a simple Bluetooth device with the help of NFC, no pairing shall be performed. In short, I just want to get the MAC address of the Bluetooth device and automatically initiate a connection to this MAC with a certain application (e.g. the Master Control Panel). How can I do this?

I had a look at the record_launch_app sample, but that only seems to start an application (it doesn't seem to hand over the MAC address to the application). The nfc hrs sample, on the other hand, initiates a pairing process that I don't want (because my device doesn't support pairing).

After looking into the ndef specification, I couldn't find a ndef record type that is used for connection to a Bluetooth device / MAC. Did I just miss it? Or is this not considered a common use case of NFC?

You are correct that there is no "standard" NDEF record that is used to pass the MAC address of a device to a peer and automatically initiate a connection with said device.

However, it is possible to create custom NDEF record that can be used to pass the MAC address of peripheral to a central. Please see this Infocenter page on how to create custom NDEF records.

Thanks, just as I suspected. So this will be some extra work on Client side, too (e.g. link the custom NFDF record to an intent on Android).

(not like the URL NEDF record that automatically triggers an URL intent on Android).
