ESP8266 Community Forum

- Sat Jun 20, 2015 7:25 pm #21061 The ESP options disappeared from the IDE this morning so I went into board manager and sure enough it wasn't showing as installed. Long story short, it installed v-835 and now nothing that was working yesterday is working today. Everything throws an Exception (28) - sometimes it gets out of setup() but mostly it dies there. I've tried with two different boards using known working good setups and code.

I'd like to go back to one of the earlier versions to see what problems, if any, follow; how do I point it back to one of the earlier versions that I was using (816 for example)?

Thanks,
Brad

Goes to where they are kept .go to packages and see whats listed . If you have 2 delete the last and see if that works . I think it should but I have not done it

I am not sure its working ! but if you delete them all and have preferences update turned on its supposed to automatically update when you open Arduino again

Get you modules here:

There's a buildprefs.txt file in the temp directory where it does the build but for the life of me I can't find where it's pulling that data from.
