I trying to get ATT_PrepareWriteReq to work with BTool and I get the following results which appear to indicate that the command made it to the dongle OK but not to the server since the command never completed with a Prepare Write Response (as indicated on page 515 of version 4.1 [vol 3] of the Bluetooth Spec (Attribute Protocol). I am assuming (correctly????) that the HCI_LE_EXT_Event) came from the dongle and not the LE server, any ideas out there?
