Ack reception timeouts when trying to connect camera

1

I have a Basler a2A2590-22gmBAS that I’m trying to set up with aravis in link-local mode.

If I don’t set up a DHCP server on my system, it falls back to link-local, which is expected.
However, when I stop my DHCP server and reconnect the camera, I get Ack reception timeout messages when trying to connect to it:

Relevant output of ip a (the interface where my camera is connected to):

5: enp138s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 8192 qdisc mq qlen 1000
    link/ether 74:fe:48:68:a3:66 brd ff:ff:ff:ff:ff:ff
    inet 10.1.0.1/24 brd 10.1.0.255 scope global enp138s0f1

    inet6 fe80::76fe:48ff:fe68:a366/64 scope link 
       valid_lft forever preferred_lft forever

Is it not possible to communicate with this camera in link-local ip mode?

Right before pressing the ‘Create topic’ button I noticed the cause of the issue, decided to post anyway to share the solution:

I created the interface address 169.254.100.1 with a /32 subnet mask, but this should be /16:

ip addr add 169.254.100.1/16 dev enp138s0f1

The camera obviously cannot connect to this interface because it’s in another subnet (169.254.253.58/16, not /32)
