Motor don't run... #15

Closed GianCann closed 5 years ago

GianCann commented 5 years ago

I have one Smart Hub and one train motor from LEGO City Train. I haved used Raspberry 3 B+ with last Raspbian version. After installed Noble Library (https://github.com/noble/noble), and Node-Poweredup, i have activate the BT and execute the example to start/stop motor for 2 second with this command: node lego.js

The Led on Smart Hub becomes fixed, but the motor (connected to port A) don't start.

The console report: noble warning: unknown peripheral 90842b00420c noble warning: unknown peripheral 90842b00420c noble: unknown peripheral null connected! noble: unknown peripheral null connected! noble: unknown peripheral null connected!

What am I doing wrong?

Could you tell me which version you have (in the package.json)? And then could you set "export DEBUG=poweredup,lpf2hub,puphub" in your console before you run node, and send me some more debug from that?

Thanks!

(I've first restart the Raspberry)

Now i see:

But the motor always don't run

Thanks. I think I see the problem, and it's related to a change I made just yesterday. Could you try v1.7.4?

I think the problem might be related to a delay I added to discovery to wait for all Bluetooth advertisement packets to arrive. Introducing this delay added asynchronicity to the discovery process. This conflicts with a restart of the noble discovery process I have to get round some discovery issues on some platforms (Which I might have to fix some other way!)

Please explain how to do this (I'm new on node.js)

nathankellenicki commented 5 years ago

How did you install the original version you have? :) Either:

a) git clone this repo again (which will get you latest) b) Delete your node_modules directory and re-run npm install node-poweredup (which will also get you latest)

See here for more info: https://docs.npmjs.com/downloading-and-installing-packages-locally

nathankellenicki commented 5 years ago

I think the easiest route for you to get started with this project is:

  1. Create a new directory to put your project in, and change to that project.
  2. Run "npm init -y" to initialize the project with a package.json file.
  3. Run "npm install node-poweredup --save" which will pull this library into your project's node_modules directory, and save the version to your package.json.
  4. You can now write code in that directory that uses node-poweredup.

Ok, now it's work well!. Thank you.

Can you tell how can integrate this node in Node Red to send command to start/stop/change speed?

nathankellenicki commented 5 years ago

I'm afraid I don't use Node-RED, however from a cursory look at the documentation, you want to follow these guides for creating a "node" which you can use in your Node-RED pipeline - https://nodered.org/docs/creating-nodes/
