GPS tracker - TK103/TK10x
This flow is for GPS tracker devices that require a "logon" and "heartbeat" response, these have to be answered upon connection.
Change the TCP port to your liking.
In the Switch Node, decisions are made based on incoming traffic. The GPS tracker usually sends eg.:
Logon request: ##,imei:359586015829802,A;
Flow sends: LOAD
Heartbeat requests: 359586015829802;
Flow sends: ON
Change the switch node to match your imei.
End result is an object with converted longitude/latitude coordinates, speed etc. The format works with node-red-contrib-web-worldmap
Example sql statement is in the function node.
Send an SMS to your tracker: imei<passcode> to determine your imei
