I am trying to create a WiFi hotspot (from the int connection) on a small test file server running a near stock CentOS 7 (the sort of unsupported 32bit AltArch version), but NetworkManager does not seem to want to manage the device:
$ nmcli dev status
DEVICE TYPE STATE CONNECTION
enp0s2 ethernet connected ext
enp3s1 ethernet connected int
lo loopback unmanaged --
wlp0s2 wifi unmanaged --
I have tried adding managed=true to /etc/NetworkManager/NetworkManager.conf, and /etc/network/interfaces does not exist. I have tried creating various ifcfg files manually using nano, vim, nmtui and other methods (no GUI is currently available) - it does not recognise it automatically.
How can I get NetworkManager to use the wifi device? It works on other computers, and though I could reconfigure the network with something else, there doesn't seem to be any obvious solutions I have found to get it to work (I have found lots of stuff on getting it to NOT manage devices).
EDIT: Network manager does sort of recognise the custom ifcfg profile - it shows in nmtui profile editor (but not in the 'Activate Connection' bit), and when restarting the process it shows:
Oct 21 18:05:53 HOSTNAME network[6076]: Bringing up interface USB-Hotspot: [ OK ]
but does not seem to associate with the device despite having the correct MAC and interface addresses.
EDIT2: Here is one of the inital files (/etc/sysconfig/network-scripts/ifcfg-USB-Hotspot - MAC etc blanked)
HWADDR=XX:XX:XX:XX:XX:XX
ESSID="26-3"
MODE=Ap
KEY_MGMT=WPA-PSK

I have just tried various other incantations of it as well, including this (based on the working config file off another computer, using the same wifi adapter):
HWADDR=XX:XX:XX:XX:XX:XX
ESSID="wtop"
MODE=Ap
SSID_HIDDEN=yes

I when I first installed this ages ago I also had a problem that the NIC added post install was also not managed, but I reinstalled CentOS for something else and it worked then. I have got this sort of thing to work using NetworkManager and other things (hostapd, udhcpd, etc), but this is a bit odd.
Also, nmtui:

And when created manually I did do the required /etc/sysconfig/network-scripts/keys* files.
