Failed to open device, err: no supported devices available

[minhajakhterkhan199]

When I am running discoverer.go from example I am getting error no supported devices available.
In addition, my Ubuntu 16.04 is successfully able to discover and connect to devices.
Please advise hwo to solve the issue.

go run examples/discoverer.go

Perhaps a little late. I was having the same issue then executed the example with administrator rights.

For your kind info, already fixed that issue.

It takes root privilege and exclusive access to the HCI device.

1. Try execute the program with sudo. (but you mentioned that you already did.
2. See if there are other program grabbing the device, such as blued or other daemon.

BTW, more recent efforts for BLE with GO can be found at:
