照著kaiguan.lua改的，兩個(gè)倒是都能控制，不過(guò)LED1打開(kāi)關(guān)閉一次，設(shè)備就離線了，是我想法不對(duì)嗎？

你試一試，D4好像是串口

改為以下就可
if r.M == "say" then
if r.C == "play" then
gpio.write(LED, gpio.HIGH)
ok, played = pcall(cjson.encode, {M="say",ID=r.ID,C="LED turn on!"})
cu:send( played.."\n" )
end

if r.C == "play1" then
gpio.write(LED1, gpio.HIGH)
ok, played = pcall(cjson.encode, {M="say",ID=r.ID,C="LED1 turn on!"})
cu:send( play1ed.."\n" )
end

if r.C == "stop" then
gpio.write(LED, gpio.LOW)
ok, stoped = pcall(cjson.encode, {M="say",ID=r.ID,C="LED turn off!"})
cu:send( stoped.."\n" )
end

if r.C == "stop1" then
gpio.write(LED1, gpio.LOW)
ok, stoped = pcall(cjson.encode, {M="say",ID=r.ID,C="LED1 turn off!"})
cu:send( stop1ed.."\n" )
end

很厲害了，我的到現(xiàn)在還沒(méi)頭緒呢

我已經(jīng)成功用一個(gè)模塊控制 多路
