I have some generic questions about how the Particle Cloud server works and how it deals with retries / timeouts when you try to do a function call:
- Does the Particle cloud actually use the spark-server and/or spark-protocol libs? Can I use those for reference for how the Particle REST API internally works? (So that I can answer questions like these without bugging yall
- What are the timeout/retry semantics of remotely calling a Particle function (e.g.
particle call device ...)? Does it just fire off a single CoAP request to the last known device IP and wait for a response within that timeout? Or does it retry a few times (I’m guessing if this were the case there’d need to be some kind of idempotent key to prevent calling a function twice - or perhaps there’s some kind of sequence number in CoAP that prevents this)?
