CC2745R10-Q1: Missing scan response data/event

Hello,

Can I see your sysconfig settings for the Observer Configuration? Additionally, do you mind providing an air trace (Ellysis log)?

Hi,

Please find the sysCfg settings below.

Observer settings overview:

Advertising report sub menu:

PDU filter sub menu:

By default, under PDU filter the "scan response only" was not enabled. I tested it by enabling it but still the same issue.

Presently .at my desk I don't have a sniffer with me. I'll try to collect logs once I have received it. 

When I scanned the Gopro device from my android phone, I have captured the logs. In those logs I can see that the GOpro is responding with a scan response message, screenshot of the same I attached below. Hope this helps.

Hi,

While I'm waiting for the Ellysis logs, can I see the code used for parsing through the report?

Looking at the advreport structure:

bits 0 through 4 indicate whether it's a legacy adv or a scan response. It may be that a second report is coming in, but being ignored.

Seeing the code would verify this.

Hi Nima, 

Please find the code snippet of how the data is being parsed.

Contents of the scanEventHandler:

Please refer the "BLEAPPUTIL_ADV_REPORT" case.

void Central_ScanEventHandler(uint32 event, BLEAppUtil_msgHdr_t *pMsgData)
{
BLEAppUtil_ScanEventData_t *scanMsg = (BLEAppUtil_ScanEventData_t *)pMsgData;

switch (event)
{
case BLEAPPUTIL_SCAN_ENABLED:
{
centralScanIndex = 0;
MenuModule_printf(APP_MENU_SCAN_EVENT, 0, "Scan status: Scan started...");

break;
}

case BLEAPPUTIL_SCAN_DISABLED:
{
uint8 i;

for(i = 0; i < APP_MAX_NUM_OF_ADV_REPORTS; i++)
{
memset(&centralScanRes[i], 0, sizeof(App_scanResults));
}

// Go over the advertise reports that was saved in the host level and save it
for (i = 0; i < scanMsg->pBuf->pScanDis.numReport; i++)
{
GapScan_Evt_AdvRpt_t advReport;
// Get the address from the report
GapScan_getAdvReport(i, &advReport);
// Add the report to the scan list
Central_addScanRes(&advReport);
}

break;
}
case BLEAPPUTIL_ADV_REPORT:
{
if(handleAdvReport(&scanMsg->pBuf->pAdvReport))
{
Serial_Write("Device Found", sizeof("Device Found")-1);
}
}break;

default:
{
break;
}

}
}

Note: In my initial Query, you can see that there is a screenshot of the contents of scanmsg. The evtType variable has a value of "0x1B".
