can i save this firebase config on sd card and then on booting process esp8266 read config from sdcard?
#define USER_EMAIL "firstname.lastname@example.org"
#define USER_PASSWORD "mypassword123"
#define STORAGE_BUCKET_ID "mybucket.appspot.com"
#define DATABASE_URL "default-rtdb.firebaseio.com/"
so the goal is when we change the firebase configuration at any time, there is no need to do hard programming, just change the configuration stored in the SD card file.
