3.1.2 Using AP Mode
The following sections describes how to use AP mode, including connecting to the
module, checking for the last device connected over TCP, viewing associated devices,
enabling the link monitor, and routing data between clients.
3.1.2.1 CONNECT TO THE MODULE
Once the module boots up in AP mode, any client device can associate with the net-
work the module is broadcasting. Once associated, the module’s DHCP server assigns
an IP address to the client device.
The default lease time is 1 day i.e., 86,400 seconds. You can configure the lease time
using the set dhcp lease <value> command, where <value> is the time in seconds. To
view a list of devices associated with the module, use the show lease command. The
command output is in the following format with commas delimiting the fields:
Figure 3-1 shows example output from the show lease command.

Once a client is associated to the network, it can open a TCP connection to the Roving
Networks’ module. After successfully opening a TCP connection, the client receives a
*HELLO* message. The Roving Networks’ module prints *OPEN* on the UART, indi-
cating an open TCP connection.
Note: This command does not survive power cycling. After a power cycle, the
module behaves according to the wireless join policy determined by the set
wlan join <value> command.

Note: In AP mode, the module can assign a DHCP lease to 7 clients. However,
not all clients report the host name. In this case, the module reports the
name as an asterisk (*).
