The Photon Guide explains how to go into safe mode. One reason – perhaps the ONLY reason? – to enter safe mode is when you are in, say, Manual mode in your application and you cannot get to the cloud to allow a re-flash. I understand that and wonder if there are more reasons for entering safe mode.
My real question is: What happens now that you are in safe mode? Is it true that the only thing you can do, or would want to do, is flash a new application?
Normally I would just play around with the Photon and try to discover how it works. But there are too many forum posts discussing “stuck in safe mode”.
I only use the web IDE, Particle.build.
Our application uses Manual mode. We added a button on an unused Photon pin such that, when pressed, it forces the app to connect to cloud so we can re-flash. But I would prefer not to sacrifice a pin if safe mode really works properly. There are only so many pins!
