Maybe everyone else knows this, but I just discovered that you can connect to the M5stickC over the serial connection and get a python prompt!

I want to access the pre-existing WiFi config from micropython, the one you setup with M5burner.

On 1.4.5, on the M5StickC, the SSID + password are stored in apps/config.json. This is cool, as I don't have to hard-code it into my apps.

On 1.5.1, on the Core/Gray, there does not appear to be any equivalent file, yet it still knows the information. How do I access it?

I tried wifi_history = machine.nvs_getstr("history") from WifiCfg.py, but machine doesn't have nvs_getstr().

Is there any way to get this now? I really don't want to go back to hard-coding!

It there a more recent version of the micropython source than https://github.com/m5stack/M5Stack_MicroPython, which appears to be fairly old? (last updated on Aug 11, 2019). Or is that what's being used currently?

I found https://github.com/m5stack/micropython, which is more recent (Oct 31, 2021), but it doesn't seem to be as complete: For example, the tft code doesn't seem to be there.
