I am a relative newbie to Minecraft. I setup a little Minecraft server (Nukkit) on a Raspberry Pi a few weeks back for my daughter.
We can not figure out how to get Pistons to do anything.
We tried placing a block of Redstone directly under a piston. Nothing. We tried making a trail of Redstone dust with a lever. We pull the lever, the Redstone dust lights up but the piston does nothing? We tried both normal and sticky pistons.
We tried putting a block of dirt on top of the piston, still nothing.
We typically play from our iPhones, but I tried from Windows 10 MS Store version and have the same problem.

SOLUTION: As @SF. noted in the accepted answer below, Nukkit is lacking support for pistons and is missing some items in inventory.
In investigating a replacement that would run on a Raspberry Pi 3B+, I stumbled upon a maintained fork of Nukkit, called PowerNukkit. This appears to solve the redstone-powered issues (at least piston operation) that are present in Nukkit. It also adds additional items for your building pleasure.
I simply backed up my nukkit directory, downloaded the latest JAR for PowerNukkit, placed it in the nukkit folder, renaming it to nukkit.jar, and then restarted my server.
Pistons now work.
Pistons don't work on Nukkit and it's going to be a good while until they do. It's a minimalistic server missing some quite important features. You may try your luck with vanilla server for Bedrock which is currently in alpha, or run a Java Edition server with GeyserMC which is a bridge/converter software that allows Bedrock Edition players to play on JE servers.
4How to: Activate a piston.
The first thing you need to know is where the red stone dust or block (also known as “input”) needs to go. An input must face any side except the top piston part (ie the thing that pushes the block).
In addition, if you are using red stone dust, you need to make sure that it is facing directly into (not beside) the piston. This can be confirmed if the dust suddenly stops in a line facing into the piston.
If that doesn’t work…
• Make sure that the piston is not pushing >=12 blocks.
• Make sure that the piston is not trying to move an immovable object (think obsidian, bedrock, chests)
• Try placing a repeater facing into the piston, then power it.
