Hi,

Given the high profile of iwd and advocating connman with iwd, I
believe someone have already built Yocto connman and iwd,
surprisingly, I could not even find an iwd recipe in
https://github.com/openembedded/openembedded/tree/master/recipes, nor
can I find connman document and instructions to replace wpa_supplicant
by iwd, what could I be missing here?

Appreciate your kind advice.

Thank you.

Kind regards,

- jh

Thanks Tim for the link, I have built the iwd.

According to Daniel's advice to configure with "--disable-wifi,
--enable-iwd", I added PACKAGECONFIG[wifi] = "--disable-wifi,
--enable-iwd", to override PACKAGECONFIG[wifi] in oe-core
connman_1.40.bb. The intention is to remove wpa-supplicant and to add
iwd to connman_1.40.bbappend, it built the image without error, I
believe that the syntax is OK, but the wpa-supplicant was still built
and packaged. Any idea from OE/Yocto insiders why PACKAGECONFIG[wifi]
in bbappend is not effective?

Daniel, how can I verify in the Linux console if the connmand is
running with iwd or with wpa_supplicant? I have disabled
wpa_supplicant.service, and I'll remove wpa_supplicant completely when
I find a way to do it.

Thank you.

Kind regards,

ConnMan will only show the WiFi technology when the wpa_supplicant or
iwd is running the background. So it's pretty simple, if iwd is running
and ConnMan knows about WiFi, things are setup correctly.

Allright great, much better.

We have been using Yocto with ConnMan and wpa_supplicant  for many years
(since Jethro I think), and it worked pretty well each time (except few 
regressions, sometimes).
I have started the integration of iwd, and started to contribute some fixes.
Unfortunately, as it is not my priority, I have stopped working on it, and 
I have still not reached the same behavior as with wpa_supplicant, for now.

There where some major changes with Honister, maybe you should 
update to Hardknott, as first step, and add the 1.40 recipe on it
as second step.

B.R.

Hi Emmanuel,

Yes it worked on 1.37 with wpa_supplicant built by Zeus if you would
like to see the result, sorry very lengthy :-):

I don't think it is a connman issue, it seems to me my Yocto build
problem, something wrong with the libraries, dbus, wpa_supplicant, and
other network things, as per Daniel's advice, it is better to move to
use iwd, but I have the same problem for both connman with
wpa_supplicant and connman with iwd, both broken dbus and could not
get WiFi IP address, I think that dbus failure could be related to the
failure of IP address, I'll keep digging.

Are you using connman with wpa_supplicant or iwd when you built
Hardknott? If your connman works on Hardknott, it should also work on
Honister, just be careful the syntax has been changed to use : not _,
for example do_install::append, FILES:${PN}, it took me a while to
lean the new syntax.

Thank you.

I have no idea about the integration of ConnMan 1.40 on Honister, I have updated
it by myself on Hardknott with additional patches, integrated after the 1.40.

> Could you please elaborate how the DHCP works in connman with iwd and

I think normally it shall work directly, no need to configure something special to
activate it by default. My meaning was to (re)activate it dynamically to check
if it worked in that case, for example by calling:
gdbus call --system -d net.connman -o ${SERVICE_PATH} -m net.connman.Service.SetProperty IPv4.Configuration "<{'Method': <'dhcp'>}>"
after a
gdbus call --system -d net.connman -o ${SERVICE_PATH} -m net.connman.Service.SetProperty IPv4.Configuration "<{'Method': <'manual'>}>"

Pretty strange... Can you confirm it worked with your former configuration on 1.37?

To keep moving, I propose you to test the following configurations,
and check if you get back a coherent service list:
1. PreferredTechnologies=wifi in main.conf, 
2. ConnMan HEAD on Honister
SRCREV = "0ef47336dc92b101c6d87ed3a9fff4db36096007"
3. ConnMan 1.37 (from Zeus ?) on Honister
4. ConnMan 1.39 on Hardknott 

By our side we will migrate to Honister next weeks / months, but I hardly
doubt your problem is related to Yocto integration.


Best Regards,

Emmanuel

Hi Emmanuel,

Thanks for your advice.

> Have you checked that your IP configuration method is hdcp?

When I built connman 1.37 with wpa_supplicant on Zeus, it managed both
WiFi and 4G LTE network interfaces well. I did not configure anything
for DHCP, I did not even find DHCP package and running dhcpd service,
I thought that wpa_supplicant managed DHCP server and connman managed
DHCP client, is it correct? I only had DHCP issues when I upgraded to
Honister connman 1.40.

Could you please elaborate how the DHCP works in connman with iwd and
how to configure DHCP?

> Maybe checking the services list will give a clue:
> dbus-send --system --print-reply --dest=net.connman /
> net.connman.Manager.GetServices

The dbus is indeed broken, any clues how to debug it further?

# dbus-send --system --print-reply --dest=net.connman / net.connman.
Manager.GetServices
method return time=1628090207.390874 sender=:1.3 -> destination=:1.39 serial=522

Thanks for tips, I added those and rebuilt them, but it does not make
any difference. here are more debug logs:

connman should send dhcp requests repeatedly, that seems another issue.

Hi Jupiter,

Pretty strange that you are facing such problems on dhcp,
which is a basic major feature.
By my side, I have been using wpa_supplicant, via yocto, for years,
on set-top-boxes deployed projects and it works perfectly, after few patches,
maybe you can try the HEAD.

Have you checked that your IP configuration method is hdcp?
Maybe checking the services list will give a clue:
dbus-send --system --print-reply --dest=net.connman / net.connman.Manager.GetServices

I have started the migration to iwd, which required some fixes, and I have still
not reached the same behavior as with wpa_supplicant (but I am close).
Unfortunately, I had no more time to spend on this activity, but I hope giving
a new try before Christmas.

To integrate iwd on yocto (hardknott), in connman recipe, we are using this line:
PACKAGECONFIG[iwd] = "--enable-iwd --enable-wifi, --disable-iwd, iwd, iwd"
And to activate it via the local.conf
PACKAGECONFIG_remove_pn-connman = "wifi"
PACKAGECONFIG_append_pn-connman = " iwd"

Best Regards,

Emmanuel

Hi Daniel,

I finally built and managed to run connman 1.40 with iwd, the
wpa_supplicant is disabled, but there is no WiFi IP address, who is
running DHCP, connman or iwd? Running  CONNMAN_DHCP_DEBUG=1 connmand
-n -d src/dhcp.c:src/network.c, it did not send DHCP discover
requests, something is broken or not configured properly.

Thank you.

Hi Daniel,

Greatly appreciate your kind response, please see my comments and
clarifications:

Yes, I indeed have issues with 1.40 after upgrading to OE Honister,
the WiFi connection is broken, the connman 1.40 assigned a
169.154.0.0/16 range IP address, no DHCP message received:

connmand[9988]: DHCP index 3: switch listening mode (0 ==> 1)
connmand[9988]: DHCP index 3: sending DHCP discover request
connmand[9988]: DHCP index 3: sending DHCP discover request
connmand[9988]: DHCP index 3: sending DHCP discover request

No DHCP packet response received.

Please correct me, but I believe dhcp server is managed by connmand as
I found dhcp.c in the connman source, the dhcp issue is not related to
wpa-supplicant, right?

I am running CONNMAN_DHCP_DEBUG=1 connmand -n -d
src/dhcp.c:src/network.c, please let me know if you need more debug
messages.

That is fine, I can see clearly the connman direction, I'll move to
using iwd for testing, I am still learning connman, not in the
position to contribute in development, but at least I can contribute
for testing and debugging :-).

> ./configure --disble-wifi --enable-iwd

I'll try it in Yocto build.

My IoT device is running both WiFi and 4G LTE network interfaces, I
definitely need connman to manage network switching between 4G LTE and
WiFi .

Thank you very much Daniel.

Indeed, I recommend to use iwd instead of wpa_supplicant. There is no
active development happening in ConnMan on the wpa_supplicant
plugin. That means the wpa_supplicant plugin might work perfectly fine
for your use case and there is no need to use iwd. But don't expect any
big help if there are problems with wpa_supplicant.

Hard to answer as there is not definition of 'stable enough'. The best
advice is to test your use cases and figure out if it fits your
requirements.

This is a question for the Yocto mailing(s) list.

> iwd?

There is none, but there is not much you need to do. During the
configure step you do something like

./configure --disble-wifi --enable-iwd

That's all.

There is no change in ConnMan's D-Bus APIs. Depending on your use cases
you might be able to remove the ConnMan from your design and only use
iwd. This is the case when you are only interested in WiFi networks. I
know some project went this way as it makes their system simpler and
more robust.

> My apology for FAQs.

No worries, I still hope someone with writing skill steps up at one
point and helps out at this front.

Please correct me, but it seems to me the connman is moving to a
direction to ditch out wpa_supplicant and to use iwd, but the Honister
still configure connman with wpa_supplicant by default, appreciate
your advice:

- Is connman with iwd stable enough?

- How can I create a connman_1.40.bbappend  to replace wpa_supplicant
by iwd configure?

- Where are the documents for configuring and building connman with
iwd? Where is the operational guidance to run connman with iwd? Can I
use the same connman dbus APIs or are there any dbus API changes to
run connman with iwd?

My apology for FAQs.

Thank you very much.

Kind regards,

- JH
