An IoT profile provides the following communication parameters between an AP and a host computer:
Domain name, IP address and port number of the host computer:
Before the AP reports data to the host computer, configure the IP address, domain name, and port number for the host computer. If these parameters are not configured, serial port data reported by the AP will be discarded.
Host computer trusted by the AP:
Configure a trusted host computer. So that only hosts with specified IP addresses can communicate with the AP and deliver configurations, protecting the AP against attacks. If no trusted host computer is configured, other hosts can also deliver IoT card configurations to the AP.
To enhance communication security, you can configure a shared key for encrypting communication data between the AP and host computers. The shared key must be the same on the AP and host computers.
The port number identifies an IoT card slot and is used for the AP to communicate with host computers.
