Hi!
I have a question. I currently am logging my GPS data to a .txt file in this format:
{"name":"8XEhx", "lat":40505, "lon":16, "time":"16:33:45"}
{"name":"6YgrX", "lat":40505, "lon":11296, "time":"16:33:45"}
{"name":"Ihg8J", "lat":5, "lon":196, "time":"16:33:46"}
{"name":"WvFme", "lat":430505, "lon":16, "time":"16:33:46"}
{"name":"Hn8TA", "lat":40505, "lon":161667, "time":"16:33:47"}
{"name":"ieLH7", "lat":40505, "lon":192961667, "time":"16:33:47"}
Now I would like to have a function to show those Points on a map.
Somehow it doesnt work properly.
What I thought is, that if you want to put points to a map you have to have something like this:
msg.payload = [
{"name":"8XEhx", lat:45, lon:19296},
{"name":"6YgrX", lat:8.130505, lon:1296},
{"name":"Ihg8J", lat:0505, lon:19296},
{"name":"WvFme", lat:0505, lon:1296},
{"name":"Hn8TA", lat:4505, lon:167},
{"name":"ieLH7", lat:48505, lon:11667}]
return msg;
Note that those are not my actual coordinates in the example.
this is my flow:

Maybe my function is not correct or I am thinking the wrong way.
Another question would be, if there is a maximum for input arguments for the worldmap?
Thanks in advance!!
