You can get IP address of ESP8266 using WiFi.localIP() when esp is connected to WiFi Router. How do you find your IP address of ESP8266? For communications within a network segment, it is used as a network address for most IEEE 802 network technologies, including Ethernet, Wi-Fi, and Bluetooth. What is MAC Address?Ī media access control address ( MAC address) of a device is a unique identifier assigned to a network interface controller (NIC).

There is simple way to convert IP address to string is using toString() function.Īn Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. That way the only way it can go wrong is if the domain gets hijacked which to be fair isn't your problem.Converting ESP8266 IP address to string or character array. When receiving a new key the endpoint immediately checks with the server that its actually a genuine update request, this will stop people bricking installations by submitting bogus key updates.ģ) during the normal course of operation the software it'll check if it has a valid key by contacting the server You can get fancy here by having private keys that only the installation and the server have, then decryption the hash with that private key, obviously if one of your customers gets hacked your going to need to change the private keys but thats simply a matter of building in an update mechanism. 1) Have your license server expire the keys every 24/72 hoursĢ) When its due to expire your license server gives domains a new key by looking up the domain name and executing a script that comes with your installation: ![]()
