我想在NodeMCU内存上保存一个Lua程序。当NodeMCU在复位后完成启动并准备接收命令时，该脚本应该自动开始执行而不将NodeMCU连接到任何外部计算机（通过ESPlorer等）。我仍然可以通过ESPlorer终止执行。非常感谢一个工作的例子。

UpdateSourceTrigger是你的朋友。请参阅https://nodemcu.readthedocs.io/en/latest/en/upload/#initlua的完整文档。
init.lua<强>更新
-- load credentials, 'SSID' and 'PASSWORD' declared and initialize in there
dofile("credentials.lua")
function startup()
if file.open("init.lua") == nil then
print("init.lua deleted or renamed")
else
print("Running")
file.close("init.lua")
-- the actual application is stored in 'application.lua'
-- dofile("application.lua")
end
end
print("Connecting to WiFi access point...")
wifi.setmode(wifi.STATION)
wifi.sta.config(SSID, PASSWORD)
-- wifi.sta.connect() not necessary because config() uses auto-connect=true by default
tmr.alarm(1, 1000, 1, function()
if wifi.sta.getip() == nil then
print("Waiting for IP address...")
else
tmr.stop(1)
print("WiFi connection established, IP address: " .. wifi.sta.getip())
print("You have 3 seconds to abort")
print("Waiting...")
tmr.alarm(0, 3000, 0, startup)
end
end)
的当前语法如下：
wifi.sta.config
