Are there any demos (or libraries) that include support for iBeacon?
Thanks

We dont have any demo showing iBeacon support.
However, QCA4020 QAPIs support standard BLE protocol hence application developer can take care of implementation of iBeacon using application note from Apple.

iBeacon code example below for anyone who cares...  you will need to replace elog() function with your own.  Dr. Wolfe


  qapi_BLE_HCI_DriverInformation_t driver_info;
  // some sort of helper macro to set driver_info structure
  QAPI_BLE_HCI_DRIVER_SET_COMM_INFORMATION(&driver_info,
    QAPI_BLE_DRIVER_STOPBITS,
    QAPI_BLE_DRIVER_BAUDRATE,
    QAPI_BLE_COMM_PROTOCOL_UART_E);

  ble_id = qapi_BLE_BSC_Initialize(&driver_info, 0);
  if (ble_id <= 0) { elog("ERROR: qapi_BLE_BSC_Initialize\r\n"); }

  char* host_version = qapi_BLE_BSC_Query_Host_Version();
  elog("ble version = ");
  elog(host_version);
  elog("\r\n");

  int8_t tx_power;
  qapi_BLE_BSC_GetTxPower(ble_id, 0, &tx_power);
  char buf[128];
  snprintf(buf, 128, "ble tx power default = %i\r\n", tx_power);
  elog(buf);

  tx_power = 64;
  status = qapi_BLE_BSC_SetTxPower(ble_id, 0, tx_power);
  if (status != QURT_EOK) { elog("ERROR: ble, qapi_BLE_BSC_SetTxPower\r\n"); }

  qapi_BLE_BSC_GetTxPower(ble_id, 0, &tx_power);
  snprintf(buf, 128, "ble tx power = %i\r\n", tx_power);
  elog(buf);

  qapi_BLE_BD_ADDR_t ble_mac_addr;
  qapi_BLE_GAP_Query_Local_BD_ADDR(ble_id, &ble_mac_addr);
  snprintf(buf, 128, "ble mac address = %02x:%02x:%02x:%02x:%02x:%02x\r\n",
    ble_mac_addr.BD_ADDR0,
    ble_mac_addr.BD_ADDR1,
    ble_mac_addr.BD_ADDR2,
    ble_mac_addr.BD_ADDR3,
    ble_mac_addr.BD_ADDR4,
    ble_mac_addr.BD_ADDR5);
  elog(buf);
