Re: How to change IP for MQTT Publisher sample for online kapua server
You can either use “west build -t menuconfig” command to open a configuration window, or modify the `prj.conf` file directly. I rather suggest the latter, as it’s clear then what exactly you’ve changed.

I’m assuming you’re using https://docs.zephyrproject.org/latest/guides/networking/qemu_eth_setup.html , in that case you need that overlay to enable appropriate Ethernet driver. There’s also an alternative way to enable networking in Qemu (https://docs.zephyrproject.org/latest/guides/networking/qemu_setup.html), in that case SLIP driver is used and you don’t need any extra overlay. This approach is considered slower though.
Genereally, I suggest to try and run the `net/sockets/http_get` sample, which should connect to the web server on the internet out-of-the-box. This should help you to verify that you network configuration is correct to reach the internet from Qemu.

Subject: [Zephyr-devel] How to change IP for MQTT Publisher sample for online kapua server
Hi, I am trying to connect the MQTT_Publisher via qemu to an online Kapua server.
I managed to connect mqtt_pub to a localhost kapua server using the "zeth" interface "./net-setup.sh"
I assume I need to change these 2 lines in prj.conf
If the kapua server is on "http://22.214.171.124:8080/" (altered ip)
1. How do I change my IP values?
2. I am currently compiling with "-- -DOVERLAY_CONFIG=overlay-e1000.conf". Do I need to change this?
