Return to Question

Very broad question here. I don't know exactly what the problem is but I'll edit this post as we narrow down the possibilities.

I think I'm running into memory constraints.

I'm running a sketch that records two temperature values every 60 seconds and transmits them to an AWS RDB via wifi. It works well for about two hours then stops. I don't know if it's a memory constraint but I suspect that it is. What other common problems (often overlooked by newbies) can cause a sketch to end after a couple hours of run-time?

Is there a simple way to add an instruction to a loop to clear the SRAM?

It's the WiFi board. It happily remains connected to my phone's hotspot but only lasts an hour or two on my home network. Working on root cause...any ideas are welcome!

Tried to Wifi.disconnect() and reconnect with no luck. Why do some networks kick the board off while others work just fine? Will look into the watchdog.
