    Problem initiating a connection to WICED Sense using bluez gattool

      I tried to connect to a the WICED Sense tag using the bluez gattool on ubuntu 14.04 LTS and have consistently gotten a failure indicating that device is busy,  even though there are no other connections.  Attached is the hcidump output.   Any insight would be appreciated.  Thanks!
