Re: Troubleshooting my wifi connection

You can try to call "erasesdkwifi", wait a few seconds and then power cycle the ESP.
This will try to perform a new RF calibration as the calibration data is related to the voltage applied to the ESP.

Re: Troubleshooting my wifi connection

Bad WiFi can be a symptom for sketchy power supply, especially when you didn't change anything else.

Measuring an analog value will be way more stable on an ESP. Especially on ESP8266.

And please don't use ESP8266 for new projects. ...

Please note you can't update via OTA on an 1MB flash unit.

You could consider replacing the flash chip for a 4M version, which makes updating a lot (!!) easier.
Also 1M builds are quite limited to make it all fit.
