Works for me also -
N7 NOT rooted. 4.1.1
N7 on internal network 192.168.1.161 (static IP address, sub: 255.255.255.0, DNS: one ISP given and one OpenDNS, Gateway 192.168.1.254 for speedtouch router)
Open app on N7
Open Chrome browser on Windows 7 computer on same network ... http://web.airdroid.com
On app - sometimes have to click on other tab e.g. tools - and then back to "connection" to show the passcode / QR code
On the Chrome browser on the PC ... tap in the passcode ... and log in

Works a treat.

(Oops - not Air PLay - I mean Air PlayIt which at the moment force closes - but like I say - Emit works great).

Hi.  I'm a diagnosed Aspie from Stockport, UK, and I adore my Nexus 7 (had for about 3 and a bit weeks I think, now - as on 29th Sep 2012).

One thing is driving me crazy however.  I live in the UK. I use my Nexus 7 with a MiFi (over 3G) when out and about. I want to use a bluetooth headset to be able to walk along, chatting to my friend in Australia.  How can I do this? I can't seem to find evidence that anybody has this functionality working.  I wrote to Google - they just reaffirmed the profiles and wouldn't suggest a device or an App but implied it would work.  So I bought a Plantronics M20 (Bluetooth 3, HFP 1.5) just to match absolutely the suggested specs. It pairs fine.  I haven't rooted and do not wish to root my Nexus 7.  I am registering on this forum specifically about this (hence including in my introduction also).  I just want to know which app will work correctly with routing the mic and earpiece audio to/from my HFP 1.5 bluetooth headset. Not hypothetically.  Not incorrectly identified by confusing headset mic non-pick-up with the very good internal mics.  Does anyone actually know?  I get the impression nobody actually really knows.  I will try Groove IP again (last time tested was with bluetooth 2.1 and although it did "work" calling my home landline phone the sound quality was atrocious and I'm not sure how well it suits my needs - from memory [I want a non-tariff app to app solution]).  Grrrr.
