Hello, this is my starting code:
int BLEHandler::SetOOBPairData(uint8_t *buffer, uint32_t length)
{
ndefTypeBluetooth bluetooth;
ndefRecord record;
ndefType ndefBt;
ndefStatus rc;
if( buffer == NULL )
return ERR_PARAM;
/* Reset bluetooth record */
rc = ndefBluetoothReset(&bluetooth);
if( rc != ERR_NONE )
return rc;
/* Get bluetooth informations - Address, Address Type, Random and Confirm value */
rc = bt_le_oob_get_local(0, &oob_data);
/* Mandatory field: bufDeviceAddress - Device Address (only for BR/EDR) */
ndefConstBuffer bufDeviceAddress = { (uint8_t*)oob_data.addr.a.val, sizeof(oob_data.addr.a.val) };
bluetooth.bufDeviceAddress = bufDeviceAddress;
/* Optional fields: Extended Inquiry Responses. Up to 8 data structures
* According to BLE spec, the data format should be: Length, EIR Data Type, EIR Data
*/
/* EIR Field 1: LE Device Address - 6 LSB bytes: Device address, 7th byte: Address type (Public/Random) */
memcpy(&eirLeAddress[2], oob_data.addr.a.val, 6);
eirLeAddress[8] = oob_data.addr.type;
rc = ndefBluetoothSetEir(&bluetooth, (uint8_t*)&eirLeAddress);
if (rc != ERR_NONE)
{
return rc;
}
rc = ndefBluetoothLeInit(&ndefBt, &bluetooth);
if( rc != ERR_NONE )
{
return rc;
}
rc = ndefTypeToRecord(&ndefBt, &record);
if( rc != ERR_NONE )
return rc;
/* Encode the record starting after the first two bytes that are saved to store the NDEF file length */
ndefBuffer bufRecord = { &buffer[2], length - 2 };
rc = ndefRecordEncode(&record, &bufRecord);
if( rc != ERR_NONE )
{
return rc;
}
/* Store the NDEF file length on the two first bytes */
buffer[0] = bufRecord.length >> 8;
buffer[1] = bufRecord.length & 0xFF;
return rc;
}
The function does not return any error code, however when I read the tag with my smartphone it always says that is an empty tag. Any idea why that is happening?
