The udhcp server is used to assign the IP to the client devices that are associated with
the access point.

• Create the configuration file udhcpd.conf in etc repository
root@imx8mqevk:~# nano /etc/udhcpd.conf
• Add the following content to udhcpd.conf file
start 192.168.1.10

interface uap0
Step 2 - Create udhcp client lease database file
udhcp server uses the database file to store all the leases that is has assigned.
• Create the lease database file udhcpd.leases in /var/lib/misc/ repository so udhcp
