Attention! This application is intended only for discovery and diagnostics of your own devices! Please never use it to hack someone, such activities are most probably illegal in your country!

btCrawler is a Bluetooth scanner and diagnostic tool for Windows Mobile Smartphones. It scans for other visible devices in range and can perform a service query. You can also query for services of your own device and do some self diagnostic stuff.

In the device list: COD means "Class of Device" (see Bluetooth specification for more info). In the output window, when the SDP services are listed, "ChId" means Channel ID, which is the RFCOMM Channel the service is listening on. It supports both, landscape and portrait screens. Also Bluejacking and Bluesnarfing is supported.


Start the application and simply press the Menu->Scan menu item to detect devices in range which are in "visible mode". After devices have been found just press the ACTION Key to get a List of detected devices and choose one. Select the Menu->SDP menu item to query for services. Use the joystick buttons to scroll the results and get back to the device list. You can also query for own Bluetooth profiles by pressing the Menu->SelfDiag menu item.


Bluesnarfing is the unauthorized access of information from a wireless device through a Bluetooth connection, often between phones, desktops, laptops, and PDAs. This allows access to a calendar, contact list, emails and text messages, and on some phones users can steal pictures and private videos[citation needed] . Some programs must allow connection and to be 'paired' to another phone to steal content, but other programs can break into the phones without any control.

The following you do at your own responsibility! If something will go wrong, nobody will be responsible for your damages!

To enable Bluesnarfing do the following:

  1. Create this registry key: \HKCU\Software\Microsoft\Bluetooth\Mode. To create the key use your favorite registry editor.
  2. Under this key create a new DWORD: "ISC" (without the quotes) with the value of 1.
  3. After that start btCrawler and click on the "Transfer" button. You will then see a new button called "Bluesnarf".

If you have successfully Bluesnarfed a phone the results are saved in a file in VCard format. You can find the file in your root folder. It's name is "Bluesnarf.txt".

Phones, which are know to be vulnerable to Bluesnarfing are:

  • Nokia 6310, 6310i (up to FW Vers. 5.51)
  • Nokia 8910, 8910i
  • SonyEricsson T610 FW:R1A081
