Hey Jeff,
there is this library from @Dan-Kouba that allows you to set the Wi-Fi credentials from an app, browser or your own app.
One thing that was discovered during the testing of such library, was that the Argon had to be running, meaning connected to the internet, or the library and settings wouldn’t work.
One thing I noted in this post here is:
The trick is to create a hotspot on your phone (with credentials sensor/sensor123 ), so the Argon can connect and the library can run.
Heads up, then.
Cheers,
Gustavo.
