CC2652R: Decoding HCI response packets

oldViking

Part Number: CC2652R

Hi,

I have the ble5_host_test project loaded onto my development board. When I send the command "GapScan_disable" I get the following response packet :

0x04, 0xFF, 0x06, 0x7F, 0x06, 0x12, 0x52, 0xFE, 0x00

From the TI HCI docs I have been able to ascertain that this is an Event packet ( the leading 0x04), but I have been unable to find information on decoding the remainder of the packet.

Is there someplace where I can find this decode information ?

Thank you

Roy

Hi Roy,

I've assigned your post internally and someone will follow up.

Hello,

Have you looked into the BLE Vendor Specific HCI guide. http://dev.ti.com/tirex/content/simplelink_cc13x2_26x2_sdk_3_10_01_11/docs/ble5stack/vendor_specific_guide/vendor_specific_guide/BLE_Vendor_Specific_HCI_Guide/index.html

Also, btool is a good tool that you can help you to decode the frames, for example:

[1] : <Tx> - 10:29:03.300
-Type           : 0x01 (Command)
-OpCode         : 0xFE52 (GapScan_disable)
-Data Length    : 0x00 (0) byte(s)
Dump(Tx):
0000:01 52 FE 00                                     .R..
--------------------------------------------------------------------
[2] : <Rx> - 10:29:03.328
-Type           : 0x04 (Event)
-EventCode      : 0x00FF (HCI_LE_ExtEvent)
-Data Length    : 0x06 (6) bytes(s)
 Event          : 0x067F (1663) (GAP_HCI_ExtentionCommandStatus)
 Status         : 0x12 (18) (bleIncorrectMode)
 OpCode         : 0xFE52 (GapScan_disable)
 DataLength     : 0x00 (0)
Dump(Rx):
0000:04 FF 06 7F 06 12 52 FE 00                      ......R..
--------------------------------------------------------------------

Hopefully this helps.

Hi David,

The link you gave me to the BLE Vendor Specific HCI Guide, does contain the decoding information I was looking for.

Thank you for your help.
