How to create connman_1.40.bbappend to enable and to build connman with iwd?

How to create connman_1.40.bbappend to enable and to build connman with iwd?

[Jupiter]

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,

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.
