Greg Young - trying to update older but working...
trying to update older but working sensESP
working unit, built on 2.6.0 , i want to change to wifi etc credentials (which at the time i hardcoded into main.cpp)
cant get it to update?
ive changed the credentials in main.cpp under app builder section..
Have erased ESP32 (using both platformIO tool, also tried using python esptool - both report success, but i continually find the ESP trying to
access the "old"wifi network ( using serial monitor, i can see it working and trying to access old incorrect SSID etc)
Then decided to build a new project .. using same (previuosly working ok) platformIO.ini file (with 2.6.0)
... after doing this, it does a bunch of platformIO stuff, and then when i try to build, i get following error
I also tried using the very latest example main.cpp and platformIO.ini files that are on github "example page" .. and also getting same below error

its a red colored fatal error that stops the build process.
ok .. solved above,
made a copy of the older working folders etc , renamed and then changed the main.cpp file only.
this presumabky picked up all the background stuff preserved from 1 year ago, and allowed it to build and load the file again to ESP.
im sure there is a better way, but after3hrs of messing around with vs code and platformIo this was my solution.
The ESP32 Arduino framework stores the wifi credentials on the device EEPROM (if I remember correctly). I've tried my best to ignore those and always use the hardcoded or filesystem values instead, but it can be a bit wonky.
I don't quite remember when the push button interface was implemented, but if your device has a button connected to GPIO2, a long button press should reset the device configuration, hopefully the WiFi stuff as well.
