СС2650 How to scan by name

Hello Arkadii,

In BLE, connections are established by the Bluetooth device address (BDADDR).

Please see the SimpleCentral example, specifically on how it filters by UUID in the ADV data during processing of the GAP_DEVICE_INFO_EVENT. You could extend this capability to filter during the same event based on the name (GAP_ADTYPE_LOCAL_NAME_SHORT or GAP_ADTYPE_LOCAL_NAME_COMPLETE) in ADV or ScanRsp data.

See SimpleBLECentral_findSvcUuid()

Best wishes

Hi JXS,

Could you help me.
You can make an example of how it should look. How to write code.
And how to use the white list when searching by name.

case GAP_DEVICE_INFO_EVENT:
{
// if filtering device discovery results based on service UUID
if (DEFAULT_DEV_DISC_BY_SVC_UUID == TRUE)
{
if (SimpleBLECentral_findSvcUuid(SIMPLEPROFILE_SERV_UUID,<------------------(GAP_ADTYPE_LOCAL_NAME_SHORT)
pEvent->deviceInfo.pEvtData,
pEvent->deviceInfo.dataLen))
{
SimpleBLECentral_addDeviceInfo(pEvent->deviceInfo.addr,
pEvent->deviceInfo.addrType);
}

}
if (!(GAPCentralRole_CancelDiscovery())) {

GAPCentralRole_EstablishLink(DEFAULT_LINK_HIGH_DUTY_CYCLE,
DEFAULT_LINK_WHITE_LIST,
pEvent->deviceInfo.addrType, pEvent->deviceInfo.addr);

}
}
break;

scanRspData in Simple_peripheral

static uint8_t scanRspData[] =
{
// complete name
0x14, // length of this data
GAP_ADTYPE_LOCAL_NAME_COMPLETE,
'S',
'i',
'm',
'p',
'l',
'e',
'B',
'L',
'E',
'P',
'e',
'r',
'i',
'p',
'h',
'e',
'r',
'a',
'l',

// connection interval range
0x05, // length of this data
GAP_ADTYPE_SLAVE_CONN_INTERVAL_RANGE,
LO_UINT16(DEFAULT_DESIRED_MIN_CONN_INTERVAL), // 100ms
HI_UINT16(DEFAULT_DESIRED_MIN_CONN_INTERVAL),
LO_UINT16(DEFAULT_DESIRED_MAX_CONN_INTERVAL), // 1s
HI_UINT16(DEFAULT_DESIRED_MAX_CONN_INTERVAL),

// Tx power level
0x02, // length of this data
GAP_ADTYPE_POWER_LEVEL,
0 // 0dBm
};

How to use the white list when searching by name?

White list in: static void SimpleBLECentral_init(void)

uint8 bdPeerAddress[B_ADDR_LEN] = { 0xAA, 0xAA, 0xAA, 0xAA, 0xAA, 0xAA };
HCI_LE_ClearWhiteListCmd();
HCI_LE_AddWhiteListCmd(ADDRTYPE_PUBLIC,bdPeerAddress);

 

Help me please.

With respect,

Arkadii.
