怎么用一個模塊控制兩個LED

照著kaiguan.lua改的，兩個倒是都能控制，不過LED1打開關閉一次，設備就離線了，是我想法不對嗎？
--use sjson
_G.cjson = sjson
--modify DEVICEID INPUTID APIKEY
DEVICEID = "10xxx"

APIKEY = "88xxxxxx"

INPUTID = "8xxx"
host = host or "www.eqytg.org"
port = port or 8181
LED = 3
LED1 = 4


isConnect = false
gpio.mode(LED,gpio.OUTPUT)
gpio.mode(LED1,gpio.OUTPUT)
local function run()
local cu = net.createConnection(net.TCP)
cu:on("receive", function(cu, c)
print(c)
isConnect = true
r = cjson.decode(c)
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="LED 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="LED turn off!"})
cu:send( stop1ed.."\n" )
end
end
end)
cu:on('disconnection',function(scu)
cu = nil
isConnect = false
tmr.stop(1)
tmr.alarm(6, 5000, 0, run)
end)
cu:connect(port, host)
ok, s = pcall(cjson.encode, {M="checkin",ID=DEVICEID,K=APIKEY})
if ok then
print(s)
else
print("failed to encode!")
end
if isConnect then
cu:send(s.."\n")
end
tmr.alarm(1, 60000, 1, function()
if isConnect then
cu:send(s.."\n")
end
end)
end
run()

LED = 1
LED1 = 2
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，我的到現在還沒頭緒呢

我已經成功用一個模塊控制 多路
