I have problem printing Bluetooth with IOS but printing normally with Android with the code below.

const handlePrintTestBLE = async item => {
  try {
    await BLEPrinter.init();
    await BLEPrinter.connectPrinter(item?.ipAddress);
    showMessage({message: 'Đang in hóa đơn!', type: 'info'});
    await BLEPrinter.printImageBase64(printDemo, {
      imageWidth: item.paper.value ? Number(item.paper.value) : 576,
      imageHeight: item.paper.value ? Number(item.paper.value) * 0.8 : 460,
    });
    if (item.paper.value == '576') {
      if (IS_ANDROID) {
        await BLEPrinter.printBill('');
        // await new Promise(resolve => setTimeout(resolve, 500)); // 500ms delay
        // await BLEPrinter.printBill('\x1d\x56\x00'); // Cut paper
      } else {
        BLEPrinter.printBill('');
      }
    }
    await BLEPrinter.closeConn();
  } catch (error) {
    const errorMessage = error?.message || error?.toString?.() || '';
    if (
      errorMessage.includes(
        'Can not find the specified printing device, please perform Bluetooth pairing in the system settings first.',
      )
    ) {
      setModalType('warningBLT');
      setNotiModalVisible(true);
    } else {
      showMessage({
        message: 'Không kết nối được với máy in này!',
        type: 'info',
      });
    }
  }
};

When running on real IOS device, it shows error like this
API MISUSE: <CBCentralManager: 0x139ea3300> can only accept this command while in the powered on state
I tried wrapping the BLEPrinter.connectPrinter function in the getDeviceList callback and it gives an error.
Can\'t connect to printer + UUID
Can anyone give me a sample code to successfully connect and print photos using BLEPrinter on IOS 🫶
