9 months ago The programmatic way is probably the best as we can be more flexible and no need to mess around with docker container changes. The problem is that this is hidden behind the layers of bless somewhere and could require us to change things in bless or work around this in some way.

9 months ago Here is an alternate ble docker that seems to work:
FROM python:3.12.1-bullseye
RUN apt-get update -y
RUN apt-get upgrade -y
RUN apt-get install -y build-essential bluetooth libdbus-1-dev libgirepository1.0-dev libudev-dev libical-dev
RUN apt-get install -y libcairo2-dev
#RUN apt-get install -y glib
#RUN apt-get install -y python3-pip
#RUN apt-get install -y python3-venv
ENV DBUS_SYSTEM_BUS_ADDRESS=unix:path=/host/run/dbus/system_bus_socket
WORKDIR /code
COPY requirements.txt requirements.txt
# this is needed as packages are now installed in the venv
ENV PATH="/code/venv/bin:$PATH"
ENV PKG_CONFIG_PATH="/code/venv/lib/pkgconfig:$PKG_CONFIG_PATH"
RUN python3 -m venv /code/venv
RUN /code/venv/bin/pip install -r requirements.txt
RUN /code/venv/bin/pip install dbus-python pycairo PyGObject
RUN /code/venv/bin/pip install python-networkmanager
COPY . .
ENTRYPOINT sh docker_entrypoint.shleaving this here as I spent most of the day getting it to work. But then it turned out to be a balena flag in the compose that was needed:
io.balena.features.kernel-modules: 1
should be set to 1 if we want to access the hci0stuff as per above...
The ble container could probably need some slimming as it is 1GB in size compared to the web that is 375MB and does a hell of a lot more...

9 months ago Spent a lot of time experimenting. Alas no real progress what ha been tried is setting of hci0 parameters:
adv_channel_map
adv_min_interval
adv_max_interval
conn_min_interval
conn_max_interval
This has possibly helped in the gw showing up faster in the pairing dialog. But not much else.
I have tried the basic example from bless, and also implemented a new version based on Nebras ble implementation (based on this repo https://github.com/Douglas6/cputemp)
One hypothesis was that the characteristics needed proper descriptors and this could not be set easily in bless. But that also did nothing.
The symptoms are a disconnect after 30 seconds and trouble subscribing to the gatt characteristic (it works sometimes). The disconnect seems to happen even in bluethooth internals (chrome://bluetooth-internals/) However other ble devices seem to work fine on my computer. Eg accessing through chrome ble internals keeps the connection indefinitely.
It also works fine on Chrome on android...
This leads me to conclude that the GW is somehow damaged and for some reason the win 11 chrome ble is sensitive to this particular flaw.
The suggested strategy forward would be to change the GW and/or possibly reinstall the current GW (Huge Walnut Hawk)

9 months ago A complete reinstall did not improve the situation. Could there be a hw issue on this GW?

We can note that on Android there is no paring request, and there is thus no failed authentication.

9 months ago using bluetoothctl in the bluethooth container some interesting stuff appears. Apparently windows sends a request to pair using a passkey. This does not happen when pairing from mobile.
One possibility that seems to work is to adapt the bluethoot agent in different ways. The NoInputNoOutput agent capability seems important. Possibly the agent should not allow for pairing.
When adding this the computer got paired to the raspberry pi (even spotify now seems to send to the rpi via some sound GATT standard)

9 months ago slow progress - but it is def related to the fact that windows want to properly pair with the gw (the whole dialog thing going on). If that succeeds then the connection is stable.
The problem is the actual paring - this does not seem to happen in the usual smooth way bur rather manual codes need to be exchanged. This seems to be related to what agent for authentication is used on the rpi. https://raspberrypi.stackexchange.com/questions/107400/what-bluetoothctl-agents-are-there
Successfull pairing has been done with the tool blutetoothctl agent command. Problem is that this in interactive tool intended for diagnostics and testing. The agent will not run if this tool is not executed via ssh etc.
Some attempts have been made to install an agent via bluez-tools (bt-agent) it seems to work but no paring has been successful. Windows at mist shows a dialog "tap to configure your bluethoot device" but after that nothing happens.
I also tried to write my own agent based on https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/test/bluezutils.py This also seemed to work but no pairing has been done using the NoInputNoOutput capability
Another step in this direction worth trying is to use https://github.com/spacecheese/bluez_peripheral where the whole service can be build... yay third implementation...
There is also information from m$ regarding their swift paring https://learn.microsoft.com/en-us/windows-hardware/design/component-guidelines/bluetooth-swift-pair
All in all productive but no real solution up and working as of yet...

9 months ago Windows now seems to give a connection failed regardless of agent.... baybe a reboot is in order soon...
h0bb3
commented
9 months ago Reboot did not help much. The device seemed to remember the connection to the computer in some strange way.
This could be fixed using bluetoothctl remove device.
Interestingly after this the custom ble agent worked and the computer and pi could be paired normally.
Another interesting find is the use of custom ble agent in the balena Bluetooth image: https://github.com/balena-labs-projects/bluetooth
They seem to have a pretty massive block for ble - unfortunately based on python 3.9 it seems. nevertheless this could be an important inspiration.
h0bb3
commented
9 months ago Yes, this finally seems to work ok on Windows 11. There could be some quirks to iron out for cases like rebooting the gateway, computer, and removing the gateway from the computer ble connections.
It also seems to work well on android chrome.

commented
9 months ago hciconfig is a handy tool https://manpages.ubuntu.com/manpages/trusty/en/man8/hciconfig.8.html
so the final thing is managing when either side unpairs the other. If windows unpairs the windows computer is remembered as paired on the gw (for some reason - but we can imagine removal happens when the laptop is not near the gw so the case still remains) This unfortunately means that a new pairing will not be allowed (this seems to be for security reasons).
The option now is to remove the computer from the gw. But the problem is when to do this. As we do not have a button for ble (yet) I opted to do this at start of the ble service. When booting the gw will check for any paired devices and try to reconnect to them, if reconnection fails then the device will be removed.
The downside is that you can end up with a computer that thinks it is still paired to the gw. This can happen if eg the gw is rebooted and the computer is not near the gw startup. The user will then need to remove the gw from the paired ble devices and then it should work.
When we get a button this behavior can be moved to some paring mode initiated by a button press.
h0bb3
commented
9 months ago So in general this seems to work. There are some scenarios:
Scenarios 4 and 5 are the tricky ones. It seems that windows sometimes remembers the gw even that it is removed (this can bee seen in the ble tray as a connection coming and going and you need to click the gateway label that shows (this is not very intuitive) Possibly this can be solved by turning ble on and off - or by looking at more windows specific pairing stuff as in the documentation.
h0bb3
commented
9 months ago So the gw does not seem to be able to reconnect when the gw is rebooted (works fine if the service is just restored) This could be caused by ble services not fully started yet etc. Have tried some different approaches here including simply just waiting for 60 seconds but it does not seem to change things.
h0bb3
commented
9 months ago So there seems to be no good way of actually coping with the need for repairing of a device when it has been removed from windows. This seems to be the major reason for having a button on all ble devices. You can throw away the old pairings and start over from scratch.
My proposal now is that we have some special commands in the ble client for this. Then you can at least log in via an android phone and hit reset. Then you should be able to pair again on Windows.

9 months ago But there is a button for BLE on the RAK GW, Helium FW. Maybe this can be utilised?
h0bb3
commented
9 months ago Yes that we will definitely do. Basically that is why it is there :)
h0bb3
commented
9 months ago Some more tests. I had an hypotheses that pairing is caused by additional ble services added as a default by bluez in the balena host os. Removing all plugin services seem to remove the need for pairing in windows.
The fix is somewhat ugly and involves stopping ble in the host os, and then restarting it in the container whit the correct parameters. This seems somewhat cumbersome and inconvenient.
There should be a dropin configuration available but idk where and how this should be edited. Tried to create it in /lib/systemd/system/bluetooth.service.d/bluetooth.service
but that did not seem to make any change.
some info here: https://forums.balena.io/t/balena-sound-bluetooth-volume-synchronisation/40901/25
At this point ther have been some instances where the connection works well, but also some where the subscription does not work and is terminated after ~30 seconds. More testing is likely needed here preferably on a computer that has not been fiddled with as much as mine...
h0bb3
commented
9 months ago This seems to work very well. I will create a new branch where this will be cleaned up to the current solution and then it will be merged with beta.
h0bb3
commented
9 months ago Some concluing remarks. It seems the agent is needed on windows and it is in general a good idea to disable Bluetooth (and enable) to get a reset ble driver on windows.
phew....
h0bb3
commented
9 months ago for some reason this has stopped working again (at least on my computer) basically from one build to another (and going back does not seem to help). Debugging the ble suggests windows terminates the connection with a timeout for some reason.

6 months ago Try this: /etc/bluetooth/main.conf the option ReverseServiceDiscovery.
ReverseServiceDiscovery = false
In general the web-ble works poorly on windows 11 and chrome browsers.
It seems there are frequent disconnects (this causes messages to not be delivered and responses to not be triggered). Even if just connecting and doing nothing the connection does not seem stable.

It seems the approach is to set the connection parameters.
This can maybe be done programmatically: https://github.com/colin-guyon/py-bluetooth-utils/blob/416a8925682d6ee4ad607936d897646a3a83a331/bluetooth_utils.py#L233
or in the container os itself (though not supported in image python:3.11)

One interesting note is that the above Nebra container also needs to wait for dbus to respond (we also have this problem but the container is simply restarted until it works it seems)
