You will have to excuse my lack of knowledge … I am really concentrating on the product and getting updated prototypes into the field as fast as possible. Previously I used Arduino Pro Mini’s so a switch to spark kept the same form factor with the benefit of remote software update. I am not a networking expert.
My 2D array is in the order of 600-800 slots at present and would be updated once/day at the most.
Not sure how that would work with Spark.function() which looks to me to be more about initiating an action in the remote.
Webhooks sounds interesting, when will it be available?
I am just about to build a buddy unit that will use a second spark to provide local control of the remote (speed, mode etc) and I plan to use Spark.subscribe() for that but I did not see the function as a major data passing tool.
Consequently it looks as though the low level approach is going to be the way forward. Any examples would still be welcome.
Thanks for your help.
