Q6: How to avoid IP address confliction when apply HF-A11 module?
¾
The following address allocation method can avoid the IP address confliction for dynamic
and static IP address mixed application.
Module dynamic IP address range from 100 to 200 for last IP address segment.
Such as default IP: 10.10.100.254. When module works as AP, the IP address
module 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 HF-A11 modules works as data acquisition card
and connect with PC, how to configure this application?
¾
Network structure as below figure: Three HF-A11 module setup 3 TCP links with PC server.
Module 1# works as AP and all devices connect to module 1# through WiFi interface;
