Anyone here know how to write android apps by any chance? Need a really simple app.

2

Try app inventor

I need to create an app that connects to the printer and sends 1 gcode command to start with. Would those 2 options that you guys listed work for this? I have no experience in app coding btw… I’m guessing some custom coding would be necessary? @Francesco_Bolzoni @KJ110813

App inventor is the easyest way i knowvto build android app.

5

I can use app inventor, but not sure if that has USB otg support, the best app I made was only a lego mindstorms remote control.

If you’ve done web development, a framework like Cordova or React Native ( https://facebook.github.io/react-native/) might help you get off the ground. I’m not sure if either of them support serial communications out of the box.

@Shai_Schechter ​ HOW should it connect to the printer? Does your printer have a Bluetooth or TCP/IP protocol that you have the documentation for? 
If it is to be a serial port emulation over USB, then Android is overkill.

@Marcus_Wolschon Sorry, forgot to mention it’s via USB cable. Any suggestions?

9

what USB endpoint-type? It would have to be something your kernel already supports unless you want to write USB kernel modules.

@Marcus_Wolschon It’s a regular USB port. Mini-B 5 pin port. I just need a handheld device to connect to the printer to send 1 gcode command and then disconnect.

BTW… it doesn’t necessarily have to be Android can be windows too. I just thought that an Android device might be the easiest to obtain because android tablets are cheap. (Never used android… I’m a Mac person).

I just don’t need an over complicated program like say for example Repetier or Cura to do this. I need a simple screen that connects to the printer and sends a command when a button is pressed.

@Shai_Schechter
I was not talking about the physical connector but about the protocol.
If you don’t know the protocol, then nobody can implement it.
It may be a serial port emulation but it may well be something different.

@Marcus_Wolschon Ok that I am not sure, but if it helps, we use Smoothieware.

There is also http://appinventor.mit.edu/explore/about-us.html which claims to get you to a basic app within an hour.
