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

josephcenk commented 6 years ago

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:

https://github.com/currantlabs/ble or https://github.com/go-ble/ble

Cheers
