This should IMO go into a sub directory like e.g. lua_examples/eus/init.lua

I agree that this init.lua is "eus" specific. I have no problem moving it to eus. However, maybe we could group all examples of init.lua together... one with eus, one for waking up after deep sleep, other situations.... All I know is that when we need those examples, they are scattered around the docs, so a directory "starting up" might also work. Its up to you, I'll follow your suggeations and update the PR.

Good idea! Do you have a naming proposal? A directory called init_lua and then files like e.g. eus-init.lua?

https://nodemcu.readthedocs.io/en/latest/upload/#initlua -> move from docs to a file in that new folder, add reference to existing docs chapter.

@blobule still interested in following up on this?

--
-- Waits 10 sec to allow stopping the boot process, and get wifi activated
-- When wifi not activated, setup a portal to select a network
-- In all cases, wifi ends up activated and the main task main.lua is executed
--
-- module needed: enduser_setup

print("Waiting 10sec... use t:stop() to cancel init.lua")
t=tmr.create()
t:alarm(10000,tmr.ALARM_SINGLE,function ()
t=nil -- free the timer
if wifi.sta.getip() then
print("Wifi activated",wifi.sta.getip())
dofile("main.lua")
else
print("No Wifi. Starting portal...")
enduser_setup.start(
"SuperBidule",
function()
wifi.sta.autoconnect(1)
print("Wifi activated",wifi.sta.getip())
dofile("main.lua")
