We have issue in dhcp server which is hosted by Jetson Nano. Our setup consists of Jetson Nano as Access Point, has dhcp server and Android Tablet as a client.
We have tried to increase the lease time in /etc/dhcp/dhcpd.conf
But it does not have any effect on lease time
Then we tried to limit the dhcp range by configuring /etc/dhcp/dhcpd.conf
I can’t answer the specific information you need, it has been a long time since I’ve worked on DHCP setup and there is much I no longer remember. However, this is not specific to a Jetson, and is in fact part of the DHCP server setup itself. Lease time is only a “suggestion”, combined with perhaps rules to attempt to allow reassignment of the same IP address during a renewal. In order to get what you want you would need to add a rule to match the MAC address of the tablet to a specific IP address. This is still “dynamic” addressing and not “static”, but it is dynamic from a pool of a single reserved IP address. To be “static” this would require the address to be set from the tablet (which I doubt is possible for Wi-Fi).
Incidentally, even if you have a pool of addresses with a range of only one, there is likely to be a conflict between disconnect and reconnect because the server does not know this is the same device without the MAC address assignment.
