B4J Question dummy questions pack for B4J in Linux

[peacemaker]

Hi, All

For industrial controller development i think about using B4J, making some background\console\service apps.
But working in Linux phone or single-board-computer.
Initially it needs to install Java, correct ?
Sure, many codes are ready from B4A and should be migrated.

So, is it possible in Linux with B4J to program, using:
* device reboot ("su reboot")
* WiFi and mobile Internet connection state toggle ("su svc wifi enable" and "su svc data enable")
* sending SMS
* UART or other IO ports data exchange - working with some sensor PCB modules, maybe of Arduino

?

You can use jShell to run these commands.

You can create a standalone package that includes Java. You can also copy OpenJDK together with your app.

If UI app in Linux is not needed - what notification ways are possible from such server app to user near the sbc?
Is there any possibility to text-to-speech in Linux & Java?

Why not send push notifications or emails from the server?
