Hello,

I have an issue working  with TI WL1283 chip, I cannot set LE mode for its, because for HCI command <LE_Set_Event_Mask> we get Command Disallowed response. Below is part of log for that situation, and couple of question about it.

According to <Command_Complete> HCI events returned on response to <Read_Local_Supported_Features> and <Read_Local_Supported_Commands> HCI commands, this TI BT chip supports LE and also supports <LE_Set_Event_Mask> HCI command.

The questions are:

-          Where to find the proper firmware version that supports LI on this TI BT chip?

-          Are there any special actions that should be performed to force TI BT chip handle LE HCI commands successfully?

 Here is detail HCI log:

 <Command_Complete> for <Read_Local_Supported_Features>

HCI EVENT BYTE [0000] = 0x0E

HCI EVENT BYTE [0001] = 0x0C

HCI EVENT BYTE [0002] = 0x01

HCI EVENT BYTE [0003] = 0x03

HCI EVENT BYTE [0004] = 0x10

HCI EVENT BYTE [0005] = 0x00

HCI EVENT BYTE [0006] = 0xFF

HCI EVENT BYTE [0007] = 0xFE

HCI EVENT BYTE [0008] = 0x2D

HCI EVENT BYTE [0009] = 0xFE

HCI EVENT BYTE [0010] = 0xDB ( = 11011011, “LE Supported (Controller)” bit is set)

HCI EVENT BYTE [0011] = 0xFF

HCI EVENT BYTE [0012] = 0x7B

HCI EVENT BYTE [0013] = 0x87

<Command_Complete> for < Read_Local_Supported_Commands >

HCI EVENT BYTE [0000] = 0x0E

HCI EVENT BYTE [0001] = 0x44

HCI EVENT BYTE [0002] = 0x01

HCI EVENT BYTE [0003] = 0x02

HCI EVENT BYTE [0004] = 0x10

HCI EVENT BYTE [0005] = 0x00

HCI EVENT BYTE [0006] = 0xFF

HCI EVENT BYTE [0007] = 0xFF

HCI EVENT BYTE [0008] = 0xFF

HCI EVENT BYTE [0009] = 0x03

HCI EVENT BYTE [0010] = 0xCE

HCI EVENT BYTE [0011] = 0xFF

HCI EVENT BYTE [0012] = 0xFF

HCI EVENT BYTE [0013] = 0xFF

HCI EVENT BYTE [0014] = 0xCF

HCI EVENT BYTE [0015] = 0xFF

HCI EVENT BYTE [0016] = 0xFF

HCI EVENT BYTE [0017] = 0x1F

HCI EVENT BYTE [0018] = 0xF2

HCI EVENT BYTE [0019] = 0x0F

HCI EVENT BYTE [0020] = 0xE8

HCI EVENT BYTE [0021] = 0xFE

HCI EVENT BYTE [0022] = 0x3F

HCI EVENT BYTE [0023] = 0xF7

HCI EVENT BYTE [0024] = 0x8F

HCI EVENT BYTE [0025] = 0xFF

HCI EVENT BYTE [0026] = 0x1C

HCI EVENT BYTE [0027] = 0x00

HCI EVENT BYTE [0028] = 0x00

HCI EVENT BYTE [0029] = 0x00

HCI EVENT BYTE [0030] = 0x61

HCI EVENT BYTE [0031] = 0xF7 ( = 11110111, “LE Set Event Mask” bit is set)

HCI EVENT BYTE [0032] = 0xFF

HCI EVENT BYTE [0033] = 0xFF

HCI EVENT BYTE [0034] = 0x7F

HCI EVENT BYTE [0035] = 0x00

….

HCI EVENT BYTE [0069] = 0x00

But BT chip cannot handle <LE_Set_Event_Mask> HCI command successfully:

HCI COMMAND BYTE [0000] = 0x01

HCI COMMAND BYTE [0001] = 0x20

HCI COMMAND BYTE [0002] = 0x08

HCI COMMAND BYTE [0003] = 0x1F

HCI COMMAND BYTE [0004] = 0x00

HCI COMMAND BYTE [0005] = 0x00

HCI COMMAND BYTE [0006] = 0x00

HCI COMMAND BYTE [0007] = 0x00

HCI COMMAND BYTE [0008] = 0x00

HCI COMMAND BYTE [0009] = 0x00

HCI COMMAND BYTE [0010] = 0x00

HCI EVENT BYTE [0000] = 0x0E

HCI EVENT BYTE [0001] = 0x04

HCI EVENT BYTE [0002] = 0x01

HCI EVENT BYTE [0003] = 0x01

HCI EVENT BYTE [0004] = 0x20

HCI EVENT BYTE [0005] = 0x0C (COMMAND DISALLOWED)

Thanks.
