[如何在android中配置ble广告以使ios检测到

Question

使用我当前的配置，其他Android设备可以很好地读取设置的UUID，但谈到iOS时，我的同事正在从此广告/ GATT广播中获取UUID的变体。我真的需要广播iOS版GATT来发现我吗？

开始广告：

@ReactMethod
private void advertise(Callback advCallBack) {
    ...
    private static UUID myUUID = UUID.fromString("A85A30E5-93F3-42AE-86EB-33BFD8133597");

    AdvertiseSettings settings = new AdvertiseSettings.Builder()
            .setAdvertiseMode(AdvertiseSettings.ADVERTISE_MODE_BALANCED)
            .setTxPowerLevel(AdvertiseSettings.ADVERTISE_TX_POWER_HIGH).setConnectable(false).build();

    ParcelUuid pUuid = new ParcelUuid(myUUID);

    AdvertiseData data = new AdvertiseData.Builder().setIncludeDeviceName(false).addServiceUuid(pUuid)
            .setIncludeTxPowerLevel(true).build();

    AdvertiseCallback advertisingCallback = new AdvertiseCallback() {
        @Override
        public void onStartSuccess(AdvertiseSettings settingsInEffect) {
            super.onStartSuccess(settingsInEffect);
        }

        @Override
        public void onStartFailure(int errorCode) {
            super.onStartFailure(errorCode);
        }
    };

    advertiser.startAdvertising(settings, data, advertisingCallback);
}

启动GATT服务器：

@ReactMethod
private void startServer(Callback srvCallBack) {
    mBluetoothGattServer = mBluetoothManager.openGattServer(getReactApplicationContext(), mGattServerCallback);
    if (mBluetoothGattServer == null) {
        srvCallBack.invoke(false);
        return;
    }

    mBluetoothGattServer.addService(new BluetoothGattService(myUUID, BluetoothGattService.SERVICE_TYPE_PRIMARY));

    srvCallBack.invoke(true);
}

private BluetoothGattServerCallback mGattServerCallback = new BluetoothGattServerCallback() {
    @Override
    public void onConnectionStateChange(BluetoothDevice device, int status, int newState) {
        if (newState == BluetoothProfile.STATE_CONNECTED) {
            return;
        } else if (newState == BluetoothProfile.STATE_DISCONNECTED) {
            return;
        }
    }
};

我们不需要相互连接，我们只需要扫描其存在，也许可以传递一些我现在无法从android执行的信息，因为仅包括设备名称就给我一个错误代码1这基本上意味着有效载荷大于广告包允许的31个字节。有什么建议吗？

我通过在广告数据中包含serviceData解决了这个问题。

      AdvertiseData advertiseData = new AdvertiseData.Builder().setIncludeDeviceName(true)
                .addServiceUuid(new ParcelUuid(SERVICE_UUID)).addServiceData(new ParcelUuid(SERVICE_UUID), serviceData)
                .setIncludeTxPowerLevel(true).build();
