Bluetooth LE / Mi Flora #9048

Closed adrian-ludwig closed 6 years ago

adrian-ludwig commented 7 years ago

Home Assistant release (hass --version): 0.51.2 - hass.io

Python release (python3 --version): 3.6

Component/platform: Bluetooth / BT LE tracker / Mi Plant/Flora

Description of problem: /bin/sh: gatttool: not found Result: Bluetooth LE and Mi Flora are not working at all gattlib python package is not installing because of its dependencies to glib

Expected: gatttool to exists in system

Problem & Investigation The problem is bluez package on Alpine distribution do not have "utils" like hcitool or gatttool I was trying to fix it by building from source.. I ended up with this (or something similiar):

wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://raw.githubusercontent.com/sgerrand/alpine-pkg-glibc/master/sgerrand.rsa.pub
wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.25-r0/glibc-2.25-r0.apk
apk add glibc-2.25-r0.apk
apk add boost-dev bluez-dev g++ glib-dev
apk add python3-dev

pip3 download gattlib
tar xvzf ./gattlib-0.20150805.tar.gz
cd gattlib-0.20150805/
sed -ie 's/boost_python-py34/boost_python-py36/' setup.py
pip3 install .

But this is also not working due to requirements of header for boost-python and boost-thread. But those packages are installed by boost-dev - in different versions than required (that is my assumption). Alpine packages website reports that those packages should be included in boost-dev.

TL:DR: Problem installinggattlib for python, because no glib on Alpine (because of missing deps), and no gatttool because of missing utils in bluez package on Alpine distro..

I have no idea what to do next..

Add this into that (at the end): https://github.com/home-assistant/hassio-build/blob/master/homeassistant/base/Dockerfile

adrian-ludwig commented 7 years ago

Sorry @pvizeli ! I did not explain myself clearly: The snippet I have here does not work in the end.. Still needs some deps to work. I'm out of ideas what to do next with it.

pvizeli commented 7 years ago

It look like sed -ie 's/boost_python-py34/boost_python-py36/' setup.py it not Support python 3.6. I think that need fix on gattlib

adrian-ludwig commented 7 years ago 
apk update

wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://raw.githubusercontent.com/sgerrand/alpine-pkg-glibc/master/sgerrand.rsa.pub
wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.25-r0/glibc-2.25-r0.apk
apk add glibc-2.25-r0.apk
apk add bluez-dev boost-dev glib-dev g++
apk add python3-dev

pip3 download gattlib
tar xvzf ./gattlib-0.20150805.tar.gz
cd gattlib-0.20150805/
sed -ie 's/boost_python-py34/boost_python3/' setup.py
sed -ie 's/boost_thread/boost_thread-mt/' setup.py
pip3 install .

This fixes problem with installation of gattlib.

The only thing left is missing gatttool

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates.

Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment :+1:

ChristianKuehnel commented 6 years ago

Hey @adrian-ludwig,

does this still exist in the current hassio version?

If you're using Alpine: gatttool seems to be available as part of the bluez-deprecated package: https://pkgs.alpinelinux.org/contents?file=gatttool&path=&name=&branch=&repo=&arch=

callekla commented 6 years ago

I migrated from the AIO to Hass.io today and experience the same problem with the MiFlora BLE sensor. So I can confirm that the problem persits.

ChristianKuehnel commented 6 years ago

looks like a duplicate of https://github.com/home-assistant/home-assistant/issues/3458 which will be fixed in the next release of hassio

escoand commented 6 years ago

The problem still exists in 0.61.1. I think there referenced issue if just for gattool which was added.

ChristianKuehnel commented 6 years ago

Hey @escoand ,

the point of the ticket was that gatttool was missing and that was fixed. So what exactly is the problem you're having? Can you please provide a description/error message?

escoand commented 6 years ago

As the initial comment stated it is not possible to install gattlib out of the box. There are some packages missing and the installation (exactly compilation) of gattlib on the RPi3 lasts nearly hours...

escoand commented 6 years ago

Maybe this has to be an issue at hass.io

ChristianKuehnel commented 6 years ago

Sorry I dont understand your problem. Gatttool is installed by default with hass.io version 61. It is installed from the alpine package repo. So you do not have to compile it.

And with haas 61 miflora is uaing bluepy instead of gatttol. So either way, the problem should be resolved.

So I'm a bit confused that you still have a problem there. Can you please post an error message of what is going wrong?

escoand commented 6 years ago

Ok, the point seems to be that the issue creator wants to use miflora and I try to use bluetooth_le.

escoand commented 6 years ago

Should I create a separate issue for the bluetooth_le and gattlib problem?

ChristianKuehnel commented 6 years ago

@escoand , yes please create a separate issue.

Assuming that you're talking about the Bluetooth LE device tracker, I just checked the code and it's using the gattlib library, which I'm not familiar with. Also, the solution is probably a different one than for the miflora component.

getting the following error on the latest hassio (0.62.0):

ChristianKuehnel commented 6 years ago

@rockinglama This was already fixed: https://github.com/open-homeautomation/miflora/pull/80 Will be part of the next release of the miflora library.

This only happens when the Sensor has bad reception and/or is almost out of range of your bluetooth dongle.

frog32 commented 6 years ago

This also breaks for me using hassio and 0.62.0 since the release that fixes it is not yet out should we consider rolling back to gatttool as a fix? Does that work under different environments?

ChristianKuehnel commented 6 years ago

I guess as a quick workaround, we could also just catch the bluepy.ble.BTLEException and the miflora.backends.BluetoothBackendException: https://github.com/home-assistant/home-assistant/blob/323992e224be72b9bd4af33a659eb95edee519d5/homeassistant/components/sensor/miflora.py#L144

If the connection to the device fails, there is not much that we can do, except trying again later. I did not have the time to check, if this really solves the problem...

After more investigation: The bug reported by @rockinglama is not yet fixed in the miflora library :cry:

I just opened a bug ticket there (probably for me to fix): https://github.com/open-homeautomation/miflora/issues/84

Yevgenium commented 6 years ago

@rockinglama I got the same error in versions 0.62.0 and 0.62.1
