How to create adhoc network on Raspberry pi ZERO W?

Question

I am trying to make adhoc network connect mobile phone and other pc devices to Raspiberry pi zero w

• Device :: Raspiberry pi Zero W
• Release :: 10
• Codename :: buster

I followed below steps to try to make adhoc nw on my Raspiberry pi zero w

cd /etc/network 
sudo cp interfaces interfaces.backup 
sudo nano adhoc-interface

added below in my adhoc-interface file

auto lo
  iface lo inet loopback
  iface eth0 inet dhcp

  auto wlan0
  iface wlan0 inet static
  address 192.168.2.1
  netmask 255.255.255.0
  wireless-channel 4
  wireless-essid RPitest
  wireless-mode ad-hoc

Installed dhcp

sudo apt-get install isc-dhcp-server
sudo nano /etc/dhcp/dhcpd.conf

Added below to my dhcpd.conf

  ddns-update-style interim;
  default-lease-time 600;
  max-lease-time 7200;
  authoritative;
  log-facility local7;
  subnet 192.168.2.0 netmask 255.255.255.0 {
   range 192.168.2.5 192.168.2.150;

Added my wlan0 interface to

INTERFACESv4="wlan0"

After all above on reboot, my device is able to get 192.168.2.1 ip , but its not visible on other mobile and computer devices.

Answer 1

Finally i was able to do that , i followed as below

sudo apt update  
sudo apt install network-manager network-manager-gnome openvpn openvpn-systemd-resolved network-manager-openvpn network-manager-openvpn-gnome -y 
sudo apt purge openresolv dhcpcd5 -y 
sudo ln -sf /lib/systemd/resolv.conf /etc/resolv.conf

After above i got an icon in taskbar to create a hotspot to which I was able to connect other devices.
