For my application it is important to get a PWM active as soon as possible after power on.
Some measurement we just did puts the time between power on and PWM active at around 2.2 seconds. That’s a bit long. Is there a way of speeding this up?
Is there some documentation that describes just what exactly the photon does upon power-on? For example, does it attempt to connect to WiFi before running application code? (We didn’t attempt to measure that)
Some of the info you want is in the docs under System Modes. Did you test in Automatic mode (that’s the default)? In Semi-Automatic and Manual modes, the application software runs immediately before the device connects to the cloud.
