Do you get any errors? Here it compiles just fine..
No, installing does not give any errors. But as I said bluepy-helper is not being build with the setup.py
hosted in pypi.
When you pip install bluepy
you will have the following files in the site-package/bluepy
folder of your python distribution:
blescan.py bluepy-helper.c bluez-src.tgz btle.py get_services.py __init__.py Makefile __pycache__ sensortag.py uuids.json
You can see already that there is a bluepy-helper.c
file but no object. If I run make within the folder the objects are created and the folder contains:
blescan.py bluepy-helper.c bluez-src.tgz get_services.py Makefile sensortag.py bluepy-helper bluez-5.29 btle.py __init__.py __pycache__ uuids.json
That is a setup script bug.
Ah, good catch! Actually it seems to be fixed in git already:

No, it is not fixed in in git. pip3 in Debian jessie behaves differently for a install from pypi and git url.
For pip3 -v install bluepy
it runs setup.py bdist_wheel which runs 'build' before 'install'. Compiling bluepy-helper works as expected but it is not copied to the build directory and thus not installed.
See PR #162
progress please?
I am also seeing this on X64 arch under Ubuntu 16.04.2. For the 1.1.0 release the helper is not compiled. When downgrading to 1.0.5, same thing except the ARM binary for the helper was pre-packaged as described in #127.
Note, going the non-pip route and compiling from source worked fine.
Same problem. I had to compile by hand in order to make it works (bluepy.Helper was missing, on my debian, module installed with pip3, for python3.5)
I'm having the same problem here on Debian jesse. I'm not a programmer so I'm looking for help with some details on how fix this. How do i compile bluepy-helper.c without breaking anything. Thanks
Hi guys,
You're going to have to give me some clues here. Please post a transcript of what you tried, and what the resulting messages were. If pip install
or pip3 install
methods don't work, can you try cloning the repo and doing python setup.py install
.
The helper itself can be built by going into the bluepy/bluepy
directory and just running make
.
I really can't help if I don't know which stage is failing. It works for me...
Cheers Ian
Ian, I got helper to build.
Still getting the same error.
I want to try a couple more things before I give you the rundown of what I have.
Right now I'm bouncing back and fourth between two raspberry pis and I think I'm causing myself more confusion.
Let me sort it out and I'll get you more to help me with.
Thanks for your response.

It seems that pip builds a different setup.py target by default:

Note that setup.py gets passed different targets: in the non-working case it uses bdist_wheel, while in the working case "install" is used as the target.
So I'm still struggling to reproduce this. What platform is this on, please?
And what's the output from pip3 --version
?
Thanks Ian
This is on debian unstable, the version is
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.5)
Thanks for looking into this.
Hi Ian !
Thanks again for your great work !
Well, i don't have my computer here, but i remind that it was a debian stretch up to date, with pip3 installed (i think that it was the official debian version, but maybe i did an update for a newer one, if needed by one of my python module).
I'm going to check this as soon as possible.
Cheers

So..
I did a fresh install of raspbian (debian stretch).
I have installed python3-pip (pip3 version 9.0.1)
install of bluepy (pip3 install bluepy)
Then, when i run my program (that uses bluepy), i had trouble to access the device (a TI CC2650)
So, i went in /usr/local/lib/python3.5/dist-packages/bluepy
i run make
some compilations are done
then, i restart my program : it works well.
Cheers, Sylvain

As a temporary workaround, I've changed the installation instructions to use pip install --no-binary :all: bluepy
, which seems to force it to rebuild the helper on installation.
I'm not sure whether it's possible to build wheels which have multiple architectures (i.e. various ARMs and x86's) in them; the 'net seems rather quiet on the topic.
Hi Ian,
I've seen @bennuttall talk on the topic of piwheels and he says "wheels for packages implemented in C are architecture-specific". There is more information at: http://bennuttall.com/piwheels-building-a-faster-python-package-repository-for-raspberry-pi-users/ Which references: https://www.python.org/dev/peps/pep-0425/
Hope that helps
It seems bluepy is a platform-agnostic wheel (the any
tag in bluepy-1.1.1-py2-none-any.whl
), so that doesn't make any difference. However, the lack of a Python 3 wheel means Python 3 users won't get the wheel and will have to build from source. You can upload a Python 3 wheel in addition.
Regarding piwheels, we built Python 3 wheels on a Raspberry Pi 3, which you can find here: https://www.piwheels.hostedpi.com/simple/bluepy/
Note that packages which require compilation get tagged with armv7l
(e.g. numpy)), and those that don't get tagged with any
.
In the setup.py, a compile of the C module is run so I suspect that any
is not correct value and should in fact contain the output of:
import distutils.util
distutils.util.get_platform()
As Bluepy is built on BlueZ it should indicate Linux as a minimum.
My current theory is that, because I'm not actually building a .so
extension module (I'm just happening to run make
), the system isn't figuring out that it's platform-dependent. I tried building a wheel on ARM and pushing it to PyPI, but then found that pip install
on an x86 box ended up installing the ARM executable, which it couldn't then run.
I'm guessing there's a magic config item I can override here.
Ian, I am all set. I figured out how to properly run a program as root.
It works great. Now I can move on to the intended applications.
Thank you for the support. I've read several of your posts and learned so much.
Your dedication is commendable.
Thank you
Bob

I've now made a 1.1.2 release, and build some 2.7 and 3.4 wheels for it on my Pi.
It's possible I made earlier releases with an old version of setuptools
- the hack in 6af5c30 didn't appear to work until I updated them.
Anyway, if anyone reading could confirm or deny that 1.1.2 installs for them with modern pip
, on any platform, that would be useful.
Thanks Ian
Interesting. What method did you use to upload arm wheels to pypi?
It's also been picked up by piwheels: https://www.piwheels.hostedpi.com/simple/bluepy/
Note that the wheels are for Python 2.7 and 3.4 only, so this will not work on Python 3 in Raspbian Stretch (as it's Python 3.5), or other Python 3 versions.
Are you going to upload a manylinux wheel too?

I don't quite understand what cache this refers to - since I've cleared the local pip cache in both cases... (Maybe it tries to build a local wheel in the 1st case, and building a wheel works differently from installing?)
But yeah, some improvement I'd say...
@bennuttall - I uploaded with twine
(1.9.1). setuptools
was upgraded to 36.4.0, and wheel
is 0.30.0. I'd like to get the not-building-from-source problems sorted before I start making manylinux wheels.
@simon-budig - hmm. It's possibly not picking up the wheel from PyPI because I built it for Python 3.4 (bluepy-1.1.2-cp34-cp34m-linux_armv7l.whl
) and you have 3.5. I don't know why the cache should make a difference, though, there shouldn't be any 1.1.2 wheels out there with the "pure python" flag set. Are you on ARM or x86, by the way?
This is all making a pure-Python rewrite look much more appealing...
This is on x86_64
I uploaded with twine
@IanHarvey but where did you upload it to? I believe PyPI doesn't allow uploading ARM wheels but warehouse (next-gen PyPI) does. See https://github.com/pypa/warehouse/issues/2003
On my raspbian (stretch, latest version)
apt install python3-pip libglib2.0-dev pip3 install bluepy then the same test as @simon-budig works perfectly well

As this is an x86_64 machine (a regular laptop with Bluetooth), something goes very wrong as it installs an ARM executable.
OK. Let's try again.
There's now a version 1.1.4 up on PyPI (https://pypi.python.org/pypi?:action=display&name=bluepy&version=1.1.4) which has a revised setup.py
, which invokes make
in the build_py
phase instead of install
. This works for me for both setup.py install
installation and pip install
, on two flavours of ARM.
Please note, this is an sdist
-only version for now - please don't ask for a wheel upload as I simply don't have the time to debug it.
Thanks Ian
Works on my Pi Zero W (aka the other flavour of ARM). sdist
is completely fine.
On to figuring out notifications.
piwheels isn't building at the moment, but when it kicks off again we'll pick this up and build for Pi (ARMv6 and ARMv7).
Hello guys, I have been desperately trying to install python-eq3bt on onion omega 2+ which has openWRT system. This package has bluepy as its dependency. But i've been unsuccessful at my attempts to install bluepy.
Upon research i found there is no 'make' on openWRT. And for that there is lengthy process. But I don't have that much of knowledge.
So it would be very, very helpful, if someone could help me out in this. All i want is to have an interface with the EQ3 bluetooth devices. Any help would be highly appreciated.
