I'm using IBM Bluemix Services to develop a real time application. While developing the application I need to analyse the device data (Golo4 obd2 device) on the IoT platform. Please guide me to the step-by-step information regarding the connection of the device.
I don't have one of those devices but from a quick google it seems the only way to connect it to the web is via a mobile app they provide. Perhaps you can ask the manufacture or check the instruction manual? There is no way to analyze the data in bluemix if you can't get it from the car to bluemix. It is a common architecture for this to be via a phone (bluetooth to the phone and then wifi or mobile network to the WWW). Which is why it becomes important to consider the impact on the phone's battery life and the cost to the user of the amount of data transferred and minimize both.
I have a few questions regarding onboarding a thing in IBM Bluemix IOT. My questions are as follows:
In scenario 1: Let's say I need to connect only one thing to the Bluemix platform, so I configure the device type, device, authentication token, etc., to connect the device to the platform. This is possible in the current situation.
In scenario 2: If I need to connect 50 things to my platform, will I be configuring each and every device to get the device ID, token, etc.?
Does Bluemix provide any discovery mechanism or other ways to configure things automatically?
You can programmatically register devices using bulk/devices operations. https://docs.internetofthings.ibmcloud.com/swagger/v0002.html#!/Bulk_Operations/post_bulk_devices_add
Also, this recipe describes how to register multiple IoT devices.
If you are using a gateway, devices can be auto registered:
look for "Gateway auto-registration"
Here are some other links that may be helpful.
This recipe talks in detail about how to register a device in Watson IoT Platform - https://developer.ibm.com/recipes/tutorials/how-to-register-devices-in-ibm-iot-foundation/
This Java sample shows how one can do bulk addition/deletion - https://github.com/ibm-messaging/iot-platform-apiv2-samples/blob/master/java/api-samples-v2/README.md
Came across the interesting service (Experimental) on Bluemix - Driver Behavior. Curious to know how it actually works, how does the data get to Bluemix from the car and is there a need to have an external app/device in the car to collect and post data to Bluemix something similar to Aviva's Rate my Drive app?
One simple example is to use IoT Platform and Node-RED to receive car probe data via MQTT and send the received data into Driver Behavior service in the Node-RED workflow. You can have MQTT client in each driver's smart phone.
I am not familiar with the Aviva's Rate my Drive app, but as far as I searched, you might be able to develop similar kind of application which can analyze driving behavior from car probe data with the Driver Behavior service.
Requirement was to host an application that will be accessed from multiple geographies including China.
Google App Engine was proposed for application hosting with data storage in Google Cloud SQL for relational data and Google Cloud Storage for binary content.
Understand that applications hosted on Google App Engine cannot be accessed from China (without using other products like Appscale).
if the application is deployed on Google Compute Engine instead of Google App Engine, can the application continue to use Google Cloud SQL and cloud storage and still be functional when accessed from China?
Looking forward for inputs / pointers.
Thanks
You need to enable api for your require things from your account. And you can use Google SQL and Cloud Stroage and will get full functionality when using google compute engine.
I have an iPhone game (Combination), and in the next version I would like to set up a server, where users (via the app) can submit which levels they have completed, and see how other users are doing. At this point I don't intend that users will need usernames and passwords, just a simple submit data, get back data.
I know very little about server-based language and databases, but I've heard lots of horrible things that can happen if you get it wrong. What would be the best system to design a simple, lightweight, secure database in?
How about having a look at Onyx Online or OpenFeint?
Onxy Online is from the makers of Trism, and they say, "the XBox Live Arcade ecosystem brought to the iPhone". I wrote this kind of system into Trism as a case study, and it's been a complete success. Since Trism launched in July, we've been hard at work adapting this online code for use in any iPhone game, and the results are stunning. What we're going to do is allow any developer to insert the Onyx code into their game, which will instantly enable online scoring, achievements, leaderboards, and customized forums."
OpenFeint is from the developers of Aurora Feint. From the press release:
"OpenFeint allows any iPhone game to add player profiles, buddy lists, walls, newsfeeds and real-time chat rooms allowing the game to build a real community around itself with ZERO operations overhead and minimal development time. OpenFeint consists of a server and a client. The OpenFeint Server is fully compatible with Google’s OpenSocial REST API and will be accessible through the OpenFeint client code library and sample UI code from Aurora Feint Inc. Indie developers do not have to operate the servers, which will be hosted Aurora Feint’s data center.
In a first for iPhone games, iPhone game developers will have the ability to reduce over 2 months of development work to 1 day, and completely eliminate back-end server operations, while offering their players an extensive set of customizable social and community building features:
Profiles: Players can upload an avatar photo or take one with their iPhone camera.
Walls: Each player gets a wall where other players can leave comments and view wall-to-wall conversations
Asynchronous Real Time Chat Rooms for meeting other players, sharing tips, strategies and experiences within each game community
Buddy List: Players can friend other players within their community or across the iPhone gaming community
Newsfeeds: Players can keep in touch with all of their friends’ activities (wall comments, actions in games, befriending people)
Global Community Chat Rooms for players to discuss recommendations, tips, and reviews of other games on the iPhone"
Have you used Java/C#/Perl/Python any other "server side language?" Are you going to be hosting the server-side yourself, or are you looking at hosting companies? Your decision might come down to how you intend to host your server-side stuff, and what capabilites your hosting company offers or what you are comfortable with.
Java or C# are really powerful server-side languages, but hosting these can take a little more work (and money?).
Java might be a good starting point, because you can setup Tomcat yourself and try hosting some web-services. MySQL is a good database to start with, but there are even more lightweight database alternatives. There might be a bit of a learning curve with any of these.
Have you heard of ICE touch? ICE is a middleware for network communication and has a basic persistence support. It supports every major platform:
iPhone as a client
Android as a client
Objective-C Mac OS X as client/server
C++ Linux as client/server
Java [any OS] as client/server
C#/C++, Windows .NET (with Silverlight) and native as client/server
I evaluated it some time ago and was surprised about its maturity, good documentation and example code. They name Skype as one of their customers.
As a start I would recommend to have a look at their example chat application. You can run a Java server, connect with your iPhone, your G1 and your Silverlight client and have a chat. Pretty impressive interoperabilty!
Here comes the drawback: GPL (you cannot link against it without being GPL yourself) or commercial (individual pricing).
I would also recommend you to use an online database service such as Viravis , DabbleDB or Zoho Creator. Almost all of these kinds of services have required integration capability to work with such a client as Web, Desktop, Windows Mobile or IPhone.
Java/Javascript is the defacto combo for most developers because of the Java support for every platform. Java Script has more than a few "issues"
The rest of the herd uses .NET (with its attendant 100MB run time bloatware that changes every 9 months)
php,pearl,ruby etc are good for server side, but if you want to use code, the best solution is probably C/C++ (or similar) and CGI/FastCGI.
This allows you to write communication algos once and use them on both ends. Any encryption/compresssion sim same.
