I just got the JBL Nokia PowerUp speaker for my Lumia 920, and unfortunately I can't get it to work with NFC.. It pairs with Bluetooth without any problems (with my Lumia and with other devices), but when I put the Lumia on the speaker nothing happens, except that it starts charging.
I'm guessing the nfc light on the speaker should turn on? There should be a pairing sound like with Bluetooth? And the phone should of course start playing through the speaker automatically.. Well nothing happens in my case.
I've got both the Bluetooth and the Tap+send options turned on. I've also tried rebooting the phone and switching the speaker off and on, notning...
I did have the same problem, but after I did a firmgrade update from: http://www.nokia.com/us-en/support/product/md-100w
"... but when I put the Lumia on the speaker nothing happens, except that it starts charging."
You need to tap the upper part of the back of your phone to the nfc logo between the volume up + and the previous track |<< controls before placing it on the charging pad part of the speaker to trigger pairing via NFC. There will be a sound when it works.
