And sorry i am dead tired and don't have the bandwidth to read through all the nodeMCU posts :-/
I don't want to hook up the ESP via RX TX to a usb-serial. Only once to flash such a firmware:
1. On startup it checks "client settings" and if filled it flashes the lua code from the internet/intranet and executes it.
2. With no or faulty "client settings" (access point and url from where to download lua code) it goes into server mode offering a very simply form to enter the "client settings" or directly upload lua code.
The ESP will "always" be used either in client mode or server mode anyway.
Such a (forked) firmware would only take a few bytes more
and i would happily contribute $5-$10 to a $1000 kickstarter campaign.
And would be even more happy if such a firmware already exists :-)
the Roland
ideas welcome.
