Scan error Invalid HCI Command Parameters

[justinmiller62]

when attempting to scan I get a Invalid HCI Command Parameters error. However if I run bluetoothctl scan on the scanner starts working. It appears that there is some command being sent by bluetoothctl to turn on the scanner that the software is not performing.

When I use bemoan to watch what is happening when scanning with the command parameters error I see the following looping over as the app keeps trying and failing to scan.

`> HCI Event: Command Complete (0x0e) plen 4                                             [hci0] 2.144296       LE Set Scan Enable (0x08|0x000c) ncmd 1         Status: Invalid HCI Command Parameters (0x12) < HCI Command: Disconnect (0x01|0x0006) plen 3                                          [hci0] 2.145767         Handle: 0         Reason: Connection Terminated By Local Host (0x16)

When I watch the scanner start after using bluetoothctl scan on command I get the following.
