Raspberry Issues

[justanotherstark]

Hi, I am trying to make this project work so that I can control my R2-Q5 from a Raspberry 4.

I solved a problem in yarn install with the dependency that wasn't for Linux (xpc-connection) and made it to rebuild by commenting a line in scanner.ts that had a problem with declarations (import { IToyDiscovered } from './scanner';).
After fighting with the bluetooth-hci module I managed to have everything ready but it still doesn't work.

Can someone help me?

This is the error:
sudo yarn server
yarn run v1.19.2
$ ts-node src/server

/usr/lib/node_modules/ts-node/src/index.ts:293

Try building using my forked version https://github.com/hanbang-wang/sphero-project. You can reference build.sh (but don't directly execute it since I hard coded build directory).

[justanotherstark]

Nope, the same issue.

At first yarn server says that it hasn't found bluetooth-hci and when I installed it the same error appears

[superfashi]

Did you follow every step and make sure you yarn install and yarn rebuild?

[justanotherstark]

absolutely, also checked build.sh for reference. I hoped the apt install would have installed all that was needed for the Bluetooth part

[callison-burch]

It might be worth you two doing a quick Google Hangout to walk through this issue?

I will try to install it on my laptop with windows, maybe I will have more luck

[superfashi]

Windows doesn't work for sure. Try installing docker and directly use my pre-wrote docker file. It should work with that on your RPI.

[justanotherstark]

Ok, with Docker the server works (YAY).
I have a question, am I supposed to do the python part from inside docker?
I am new to this program and I don't know how to do stuff with it.

[superfashi]

After the docker starts running, you can just run python on your local machine and it should automatically connect to docker.

[justanotherstark]

Ok, running python and "from client import DroidClient" inside one of the folder that I downloaded shows this:

Python 3.7.3 (default, Apr 3 2019, 05:39:12)
[GCC 8.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy c-extensions failed.

• Try uninstalling and reinstalling numpy.

• If you have already done that, then:

  1. Check that you expected to use Python3.7 from "/home/pi/Q5/sphero-project/r2d2/bin/python",
     and that you have no directories in your PATH or PYTHONPATH that can
     interfere with the Python and numpy version "1.17.4" you're trying to use.
  2. If (1) looks fine, you can open a new issue at
     https://github.com/numpy/numpy/issues. Please include details on:
     • how you installed Python
     • how you installed numpy
     • your operating system
     • whether or not you have multiple versions of Python installed
     • if you built from source, your compiler versions and ideally a build log

• If you're working with a numpy git repository, try git clean -xdf
  (removes all files not under version control) and rebuild numpy.

Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.

Original error was: libf77blas.so.3: cannot open shared object file: No such file or directory

Running it any other place (/home/pi) it won't find the module.

I think I am missing something here, Am I suppose to git clone at all using Docker?

[superfashi]

This is a numpy issue.

[justanotherstark]

Ok, I searched on google and after a while, I tried these commands and now everything works.

sudo apt install libffi-dev
sudo apt-get install libatlas-base-dev

Thanks for the assistance from me and my little buddy Q5
