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

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.
