NMCLI AP Mode config error | Connection activation failed: No suitable device found for this connection | Raspberry Pi 3 Model B Rev 1.2

[rafitc99]

I was trying to configure AP mode in Raspberrypi by using Network Manager. I'm using the below script. but it is throwing some errors.

Bash Script to set AP Mode

host="MyRPiAPMode"
sudo nmcli con add type wifi ifname wlan0 con-name $host autoconnect yes ssid $host
sudo nmcli con modify $host 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared
sudo nmcli con modify $host wifi-sec.key-mgmt wpa-psk
sudo nmcli con modify $host wifi-sec.psk "SomeRandomPassword"
sudo nmcli radio wifi on
sudo nmcli con up $host

Error ----

Connection 'MyRPiAPMode' (60965f2a-f510-48ef-afaf-0864242d0c06) successfully added.
Error: Connection activation failed: No suitable device found for this connection (device eth0 not available because profile is not compatible with device (mismatching interface name)).

nmcli con (After script execution)

NAME                UUID                                  TYPE      DEVICE

nmcli dev

I tried to make it availble via sudo nmcli radio wifi on
But not working.

Hi @rafitc99, Are you able to set up the AP when trying the commands individually?
