Control Printoid with ADB

You can send commands from your Raspberry Pi (or any other computed) to Printoid, if your phone (or your tablet) is plugged on it over USB.

The interface is called ADB: Android Debug Bridge.



The Premium version of Printoid can be piloted by using the Android Debug Bridge (ADB).

Controlling Printoid through ADB is a bit more difficult than from a physical keyboard since it’s not plug-n-play. But this is also more powerful, since you are able to send extra values with some commands. Typically, this is the solution I use to control Printoid with physical keys & buttons: my actuators are connected to the GPIO ports of my Raspberry Pi, then I perform a simple conversion from “GPIO action” to “Printoid command”.

You have to ensure first that ADB is properly installed on your Raspberry Pi. Then, you have to activate the developer options on your device and activate ADB.

Activate the developer options →

The first time you’ll plug your device to the Raspberry, execute the adb devices command to check if your device is properly recognized. May you will have to accept the debug bridge from the device (don’t forget to check to “remember” box)

Once you’re able to communicate with the device, here’s how to communicate with Printoid. First start the application manually, or by sending the following command:

am start -n fr.yochi76.printoid.phones.premium/fr.yochi376.octodroid.HomeActivity

Then, each control commands should be executed while the app is in the foreground, with the following schemes:

adb shell am broadcast -a PRINTOID_COMMAND --es PRINTOID_ACTION XXXX

or by passing a float value as argument (when the command requests a float value):


or by passing a string value as argument (when the command requests a string value):


Where you have to replace the XXXX by one of the following action, and when available you can complete the command with an optional value (so you have to replace YY.YY by your own float value, as for example 1.0, 5.2, 12.9…)
