Detecting IP and MAC address of Eriwin Nodes from EMS Device
Brief
Using ESP8266, we send UDP packet (IFOProbeDevice) to each IP address 192.168.xxx.1 to 192.168.xxx.255. For every Eriwin nodes, they will return MAC address, for example (IFOR00262903424eX2) is MAC 00-26-29-03-42-4E.
AT Command for ESP8266

IFOProbeDevice
+IPD,0,18:IFOR00262903424eX2 /response if the node is Eriwin nodes
