Re: New ESP-12S Module

Re: New ESP-12S Module
Posted: Thu Jan 05, 2017 11:22 pmI would think it would be the same as all the ESP-12s. Which would be 4MB. The 07's are 512kb as I recall. Depending on what firmware you're using there are several ways to query the module.

I am a bit perplexed.
Using the Arduino framework, ESP.getFlashChipRealSize() returns 1048576 bytes and my compiled sketch is 250016 bytes. However, I am unable to perform an OTA update, with the default sketch (OTA_BEGIN_ERROR) leading me to question what flash I have on this module.
