CC1352P: Gap_AdvDestroy not working

Kamlesh Parihar

Part Number: CC1352P

Using of Gap_AdvDestroy before Gap_AdvEnable corrupting advertise data and generate hard fault.

Below is my code snippet

GapAdv_destroy( advHandle, GAP_ADV_FREE_OPTION_ADV_DATA | GAP_ADV_FREE_OPTION_SCAN_RESP_DATA );
CPUdelay( 160000 );//Task_sleep(100*100);

// Create Advertisement set #1 and assign handle
GapAdv_create(&multi_role_advCB, &advParams1,
&advHandle);

// Load advertising data for set #1 that is statically allocated by the app
GapAdv_loadByHandle(advHandle, GAP_ADV_DATA_TYPE_ADV, nLen_p,
aData_p);

// Set event mask for set #1
GapAdv_setEventMask(advHandle,
GAP_ADV_EVT_MASK_START_AFTER_ENABLE |
GAP_ADV_EVT_MASK_END_AFTER_DISABLE |
GAP_ADV_EVT_MASK_SET_TERMINATED);

// Enable legacy advertising for set #1
//status = GapAdv_enable(advHandle, GAP_ADV_ENABLE_OPTIONS_USE_MAX , 0);

status = GapAdv_enable(advHandle, GAP_ADV_ENABLE_OPTIONS_USE_MAX_EVENTS , 10u);

Whenever i use Gap_AdvDestroy, advetisement gives hard fault error.

Hi,

I have assigned an expert to comment.

To confirm however, have you called GapAdv_create before calling GapAdv_destroy? I don't see that in the above code snippet.

Also which SDK version you are using?

Regards,
Michael

I am calling GapAdv_destroy before GapAdv_create and i am using simplelink_cc13x2_26x2_sdk_3_30_00_03 sdk

Hey Kamlesh,

Can you first use GapAdv_create to create the advertising set? You may be freeing up memory that hasn't been allocated for if you call GapAdv_destroy before calling GapAdv_create.

I would also recommending trying this out on the latest SDK, as we have released several updated versions since that SDK.

Hello,

I was able to add the line GapAdv_destroy at the end (after GapAdv_enable), and I saw the status return unsuccessfully, but the system did not hard fault.

Let me look into this and I will provide more detail soon.

Hey Kamlesh,

Unfortunately, after looking back, I am actually unable to reproduce this issue. After turning off optimizations, the debugger no longer halted at that line and I see that the status is successful.

Please ensure you are calling GapAdv_destroy() after calling GabAdv_enable.

Hello Ammar,

It is not working still.

Can you tell me the way where I can detect whether advertisement is completed or not?

I normally check the return status's of the API's if they have a return value.

In terms of checking the advertisements over the air, your best bet is to use a sniffer. https://www.ti.com/tool/PACKET-SNIFFER.

You can also use BTOOL(http://dev.ti.com/tirex/explore/content/simplelink_academy_cc2640r2sdk_4_10_01_00/modules/blestack/ble_connections/ble_connections.html#task-2-ndash-use-host-test-with-btool) to start a scan to search for BLE devices that are advertising. If the advertisements went over the air successfully, you should be able to view it on there. Similarly, you can search with your phone by using the LightBlue app.

I hope I answered your question!

I don't want to check it in phone or any other device. I want to verify it in software, So is there any api to detect whether advertisement finished or not.

You can use the return status off GapAdv_enable to verify if advertisements have been enabled.

Once successfully enabled, you can use a HCI_EXT_AdvEventNoticeCmd() to register for an event notification at the end of an advertising event.
