I am in a confusion with the Usb Bluetooth Dongle. I have one from ICIDU V4.0 . I wrote a program in C# using 32feet library to detect the Bluetooth devices in the surrounding as a result i can get all the devices listed (like Smart phones) except one which is BLE (Bluetooth Low Energy). I also tried changing the Usb Bluetooth Dongle and then used the one from the TRUST but couldn't succeed :(

Do i need to have a especial type of a Usb Bluetooth Dongle to connect with BLE or is it simply that 32feet.net library doesn't support BLE?

If it's the problem with the Usb Dongle then can anyone suggest me a Dongle which is easily available in the market :) and if its the problem with the 32feet.net library then which one am i suppose to use ??

Any help and suggestion is highly appreciated.

Thanks :)

You need to have a dongle that supports Bluetooth 4.0 and you have to do a different type of "scan" to detect BLE devices. A regular bluetooth scan will only detect regular bluetooth, you have to do a LE scan to detect BLE devices.

  • Thank you for your reply Tim, So this means i don't need to buy a new Bluetooth dongle? Can you tell me how can i scan the Low Energy Bluetooth in my code, what are the things i have to implement? is there any any available samples or links referring to this? Please give me some suggestions i am really in need of this. – Electronic Curious May 17 '13 at 14:10
  • unfortunately I have no experience with C#... I just know in Linux Bluez there are completely separate calls for BLE scanning and regular Bluetooth scanning. I also know they really are very different so I imagine most systems would also have them separate. First step is to confirm you have a 4.0 dongle. Then see if your library actually supports 4.0 standards such as BLE. A quick search on that website seems to indicate that it doesn't. (usually if they don't mention it, it means they don't support it) – Tim Tisdall May 17 '13 at 16:08
