readFile function with ESP32 --Solved
Posted: Thu Mar 14, 2019 1:50 pm
Thank you martinayotte for your readFile function for ESP8266.
Is there a reason it drops characters; when used with ESP32. No matter the file, this is happening.
Here is file downloaded with Filezilla:
Tried adding a delay before closing webFile and flushing webFile; both produced no change in output.
readFile function works perfectly with the ESP8266.
