Programming WiFi is part of Flowcode. I want to send just one paramter to my tablet.

My question: is there a simple android program, which can be used to show me this parameter with the protocol used by Flowcode?

With kind regards

Hi Jan,

AppInventor is once of the Android tools of choice for me at the moment but it doesn't have a nice low level TCP IP communications. It does however have some nice built in IOT style applications so maybe worth a look.

Java is the other tool of choice for Android though is fairly in depth with coding. I wrote a short article a few years back with a Java example which may be useful for you.

The file your interested in is the RPiActivity.java file in the "TCP Examples/Android/Android TCP Comms Project Files/src/RPi/Matrix/Ports/" folder.

Hi Ben,

Thanks a lot. Interesting article. But that will take a lot of time to get the program working in an android tablet. I'm hasitating to start with it.

With kind regards

Could you use Bluetooth instead?
Setup a virtual comm link and use a Bluetooth Terminal App on the tablet?

Hi LeighM

Bluetooth is indeed possible. Would that be easier?

There are many apps on Google Play that will let you use Bluetooth without any programming on Android. Some are paid and some are free with ads, and some are free without ads.

AppInventor also works great with Bluetooth and by following a tutorial is fairly simple to use to allow you to create your own apps.

Hello Jan Lichtenbelt

I do not know if the following application is suited for you but you can check the VIRTUINO APP from play store. It is created by a nice GREEK guy ilias lamprou who is very helpful and can respond to emails. He has youtube videos. The only problem VIRTUINO works with ARDUINO , so you can work with those if you have or if you can find a way to import arduino code into flowcode.

Virtuino loads a code(web server) to arduino and then based on the code you have you just add buttons (input/output) to the android app . You can add charts as well and monitor values,AND LOTS MORE.

I think if Matrix tsl can add a feature that we can import arduino code to flowcode, then by using the virtuino or any other android app we can then RAPIDLY PROGRAMMING and producing IoT projects!

I got some suggestions like:
penhab, Fhem, Domotics
But they looks not very friendly.

HMI droid http://www.idea-teknik.com/en/hmi_droid_manual.html
seems better to me.

Perhaps an idea to create a special place for IoT problems, suggestions etc. in this Forum.

With kind regards
