For an in-field device, is there the same kind of cloud access for both WiFi (Photon) and cellular (Electron)?
ie. Management of Photon through WiFi to Particle’s cloud to Particle SDK on an iOS device
and
Electron management through cellular to Particle’s cloud to Particle SDK on iOS?
Yes. From the user/developer’s point of view they work the same with regards to cloud functions, variables, publish/subscribe, etc… Both can have software updates done over-the-air and in many cases they can run the same source code.
Setup may be different if there’s a need to set up SIM cards and billing, however.
Behind the scenes it’s different (Wi-Fi vs. cellular, TCP vs. UDP transport, RSA+AES vs. DTLS encryption), but these differences are essentially hidden.
