Q6: How to avoid IP address confliction when apply DTU?

The following address allocation method can avoid the IP address confliction for dynamic and
static IP address mixed application.

DTU dynamic IP address range from 100 to 200 for last IP address segment.

Such as default IP: 10.10.100.254. When DTU works as AP, the IP address DTU can
allocate to STA is from 10.10.100.100 to 10.10.100.200;

So, if user needs to set static IP for dedicated STA internal network, the available IP address
range can start from 10.10.100.1 to 10.10.100.99.
Q7: PC works as server, all DTUs works as data acquisition card and connect
with PC, how to configure this application?

Network structure as below figure: Three DTU setup 3 TCP links with PC server. DTU 1# works
as AP and all devices connect to DTU 1# through WiFi interface;

PC Setting:

IP address: 10.10.100.100;

Network Protocal:TCP/Server, Port ID: 8899;

DTU 1# Setting:

Works as AP mode;

LAN IP address: 10.10.100.254;

Network Protocal:TCP/Client, Port ID: 8899; Application IP address:10.10.100.100;

DTU 2# Setting:

Works as STA mode;

WAN connection type: Static IP: 10.10.100.101;

Network Protocal:TCP/Client, Port ID: 8899; Application IP address:10.10.100.100;

LAN IP address: 10.10.99.254 (Different net segment with WAN port);

DTU 3# Setting:

Works as STA mode;

WAN connection type: Static IP: 10.10.100.102;

Network Protocal:TCP/Client, Port ID: 8899; Application IP address:10.10.100.100;

LAN IP address: 10.10.98.254 (Different net segment with WAN port);
