Unable to discover the devices

Jan 21, 2013 at 5:58 AM


I was trying to test to NFC in windows phone 8 emulator. I have opened two instances of emulators with 2 different resolutions. But Proximity Tapper tool is unable to find those instances. If i manually add a device nothing happens ?

Please let me know if am missing out something here.

How did you build the code? I tried building it and got an exe. Should i setup a windows phone project and try building it? Can you share me your experience on building a win 8 phone project?

I'd recommend installing the "ClickOnce" package that's already compiled for you, it'll install automatically without a need to build the EXE yourself.

A few things to be sure of:
  • The tapper tool must be running on the same host computer as your Windows Phone 8 emulators
  • When you first launched the tapper tool, it should have popped up with a Windows Firewall exception prompt as mentioned in the getting started guide. You'd need to have selected ALL 3 checkboxes on this popup and allowed the exception, by default only one checkbox is checked. If you missed this you'll need to go to the Windows Firewall control panel and add the firewall exception manually, you can browse to the proximitytapper.exe and except it from the firewall for all 3 network types.
  • To manually add the device you'll need to make sure you have the correct IP address, be aware that the Windows Phone 8 emulator actually has 2 different IP addresses, did you try with both of them?
