Bluetooth sniffer - preferably mac osx

Question

I am trying to find a bluetooth packet sniffer to capture bluetooth signals from close by devices. I would like for this application to work on mac osx. I have had difficulty finding anything at all so my requirements are low right now - something that shows signal strength and mac address would be a good start.

Answer 1

Apple publishes an application called PacketLogger.

You can download it by going to https://developer.apple.com/download/more/?=for%20Xcode (or if you have Xcode installed, go to Xcode > Open Developer Tool > More developer tools), then loging in with your Apple developer account, search for Additional Tools and download the latest version (or if you have Xcode installed, download the version matching your version of Xcode).

Although the tool is associated with Xcode, Xcode is not required to install or use it.

Prior to Xcode 8, this package was named "Hardware IO tools".

If you want the new tools to appear in Xcode's developer tools menu, drag them to the Xcode.app/Contents/Applications folder.

Answer 2

If you have xcode installed, hold the option key while selecting the bluetooth icon in the menu (upper right).

You'll see some new options in the drop down menu.

(At least for 10.5.8)
