Using NFC and bluetooth together

You would need to add your Bluetooth address inside the NDEF data beside the AAR to launch the application. Then from inside the application you parse your data and connect to the device with the specific Bluetooth address, automatically. It's discussed here a little bit.

Actually the problem seemed to be hardware related. Moving the NFC antenna to the unit I successfully tested the SW on fixed the problem. Now both BT and NFC are working together fine. The mobile application can be launched using NFC and it gets the sensor readings from the device just fine.

The only hitch is that the application (Android application) doesn't automatically connect to the device. Not sure if it can be helped but is it possible to specify some startup arguments to the application some way in the NFC initialisation ?

@jpolvi: the device usually doesn't reset itself, it's the code inside the firmware trigger a soft reset. You could probably try to debug and figure out it resets. If you try to run the "ble_app_hrs_pairing_nfc" example (where we have NFC and BLE together) what happens ? (checkout how to use it in the documentation)
