CYBT-413034-02: "LE Set Scan Parameters Command" returns "COMMAND DISALLOWED (0x0C)"

[AnHu_4662101]

Hi,

Tryin to configure the LE Scan params for my CYBT-413034-02 device returns:

Status: Command Disallowed (0x0c)

Complete command is:

hcitool cmd 0x08 0x000B 0x01 0x04 0x00 0x04 0x00 0x01 0x00

Trace:

Actually resetting the dongle before this command makes the command work.

hcitool cmd 0x03 0x0003

Yes, That's correct. You have to send HCI reset command first and see if you are getting a success response.

Then only you should proceed with next commands.
