我正在使用NodeMCU在LUA中對ESP8266 wifi模塊進行編程。我能夠從一個iPhone應用程序連接到由wifi模塊創建的TCP服務器來發送3個浮點數。我將這個巨大的字符串解析成3個字符串，並使用uart將它們發送給Arduino。它工作得很好，但大約10次輸入後，它崩潰/凍結。我需要不斷的數據流來保持未來，但始終如一，我無法可靠地做到這一點。 我在每行之後打印以跟蹤實際發生的情況，甚至之後我仍然不確定發生了什麼。TCP連接在讀取僅幾個字符串後崩潰
代碼 `
print("11\n")
wifi.setmode(wifi.STATION)
print("22\n")
wifi.sta.config("WDTS03","Walker14!")
print("33\n")
elWiFi =(wifi.sta.getip())
if elWiFi ~= nil then
print(wifi.sta.getip())
end
print("44\n")
if srv~=nil then
print("444\n")
srv:close()
print("555 \n")
end
print("Create server \n")
srv=net.createServer(net.TCP)
print("1\n")
if srv ~= nil then
print("srv !=nil \n")
srv:listen(6969,function(conn)
print("listening \n")
if conn ~= nil then
print("incoming\n")
conn:on("receive",function(conn,numbers)
print("2\n")
print(#numbers)
print("chekcing for nil \n")
if numbers ~= nil then
print("3\n")
p = string.find(numbers, "x=")
print("4\n")
q = string.find(numbers, "&y")
print("5\n")
if p ~= nill then
print("6\n")
if q ~= nil then
print("7\n")
x = (string.sub(numbers,p+2, q-1))
print("x=" .. x)
end
end --p ~= nill
print("8\n")
p = string.find(numbers, "y=")
print("9\n")
q = string.find(numbers, "&z")
print("10\n")
if p ~= nill then
print("11\n")
if q ~= nil then
print("12\n")
y = (string.sub(numbers,p+2, q-1))
print("y=" .. y)
end
end --p ~= nill
print("13\n")
p = string.find(numbers, "z=")
print("14\n")
q = string.find(numbers, " H")
print("15\n")
if p ~= nill then
print("16\n")
if q ~= nil then
print("17\n")
z = (string.sub(numbers,p+2, q-1))
print("z=" .. z)
end
end-- p ~= nill
print("18\n")
end --numbers ~= nil
print("54\n")
--conn:send("test\n")
end)
print("55 \n")
end
print("66 \n")
end)
print("77\n")
end
print("666\n")`
