I’m surprised that I haven’t been able to find a technical description of how the “Listen Mode” of the Spark works - apologies if I didn’t look in the right place and this has already been answered somewhere.
I’m totally curious how the “Listen Mode” works. Somehow, without being connected to the WiFi network, the Spark can receive the wifi SSID and password entered via the application on my smart phone. How does it do this? How can it do that securely? I’d love to know the protocol/technique employed.
