Change advertising name for NFC OOB Pairing

Hi, 

I am advertising with device name A but if someone holds a mobile to the NFC I would like to switch to NFC OOB pairing but with a different device name B (SDK version 15.2).

I am using nfc_ble_pair_init with paring mode NFC_PAIRING_MODE.

I can change the device name when stopping advertising, setting new name, init advertising again and restart it. But this works only for "normal" advertising but how to change NFC advertising?

Thanks

Andreas
