Hi Jean,

The network management library is provided by Zephyr project. You can find its document here:

Network Management — Zephyr Project documentation (nRF Connect SDK) (nordicsemi.com)

Hi, Yes I take the informations with this sample and others. But there is one big thing that annoy me: Why to search in samples and not in a documentation . I attempt to find a documentation like : net_mgmt(_mgmt_request, _iface, _data, _len) needs [list of _mgmt_request], and foreach _mgmt_request the structure of data, and so on.

Finally I do not find in the samples a way to get the ip address without to save it myself listening an event, I do not know if it is possible while I do not find it in a sample or I read it in a good documentation.

Is there a such documentation for net_mgmt(_mgmt_request, _iface, _data, _len) exists ?

Hi Jean,

Have you played with Wi-Fi: Station — nRF Connect SDK 2.5.1 documentation (nordicsemi.com)?

It can provide the following information about WiFI and Network connection state and information.
