Synchronous connections are initially created with type eSCO. Link manager may reject proposed link parameters, which triggers connection setup retry with a different set. Link type embedded in responses should be disregarded until Synchronous Connect Complete returns Success (0x00). Current code updates link type every time which creates an issue when link type changes to SCO and back to eSCO on further attepts. Issue happens with BlackBerry 9100 and 9700 with Intel WilkinsPeak on third connection setup attept 2015-05-18 01:27:57.332242 < HCI Command: Setup Synchronous Connection (0x01|0x0028) plen 17 handle 256 voice setting 0x0060 ptype 0x0380 2015-05-18 01:27:57.333604 > HCI Event: Command Status (0x0f) plen 4 Setup Synchronous Connection (0x01|0x0028) status 0x00 ncmd 1 2015-05-18 01:27:57.334614 > HCI Event: Synchronous Connect Complete (0x2c) plen 17 status 0x1a handle 0 bdaddr 30:7C:30:B3:A8:86 type SCO Error: Unsupported Remote Feature / Unsupported LMP Feature 2015-05-18 01:27:57.334895 < HCI Command: Setup Synchronous Connection (0x01|0x0028) plen 17 handle 256 voice setting 0x0060 ptype 0x0380 2015-05-18 01:27:57.335601 > HCI Event: Command Status (0x0f) plen 4 Setup Synchronous Connection (0x01|0x0028) status 0x00 ncmd 1 2015-05-18 01:27:57.336610 > HCI Event: Synchronous Connect Complete (0x2c) plen 17 status 0x1a handle 0 bdaddr 30:7C:30:B3:A8:86 type SCO Error: Unsupported Remote Feature / Unsupported LMP Feature 2015-05-18 01:27:57.336685 < HCI Command: Setup Synchronous Connection (0x01|0x0028) plen 17 handle 256 voice setting 0x0060 ptype 0x03c8 2015-05-18 01:27:57.337603 > HCI Event: Command Status (0x0f) plen 4 Setup Synchronous Connection (0x01|0x0028) status 0x00 ncmd 1 2015-05-18 01:27:57.342608 > HCI Event: Max Slots Change (0x1b) plen 3 handle 256 slots 1 2015-05-18 01:27:57.377631 > HCI Event: Synchronous Connect Complete (0x2c) plen 17 status 0x00 handle 257 bdaddr 30:7C:30:B3:A8:86 type eSCO Air mode: CVSD Signed-off-by: Kuba Pawlak <kubax.t.pawlak@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org> |
