That was mapping fields 1 through 8…
Now I’m trying to use the channel lat and long to show the device’s current position and history, without ‘wasting’ 2 of the 8 fields available.
My understanding is this is possible, (including elevation).
I have a suspicion my json string may need to include an ‘update’ directive…?
Once i have that right, i then need to start using the device locator through Google, should i not be able to acquire GPS position. … (which is the other problem I’m busy with)
There are two types of locations in ThingSpeak. One is your channel location, which is set in the channel settings page or with the channel settings API. The other is the feed location, which is a location for each measurement in a channel feed. This is the one you probably might want to use to track a device location. But, there is not a built in map (like for the channel location) for that one. You can add a MATLAB visualization as follows:
You can also do this with multiple points. (set ‘numPoints’, x) to do x points.
