I've been trying to synchronize time with ntp servers, however, nodemcu seems to ignore the server parameter. -- sync.lua sntp.sync("fr.pool.ntp.org", function() tm = rtctime.epoch2cal(rtctime.get()) print(string.format("%04d/%02d/%02d %02d:%02d:%02d", tm["year"], tm["mon"], tm["day"], tm["hour"], tm["min"], tm["sec"])) end) Execution.. > dofile('sync.lua') > 2017/05/22 21:38:39 The time response is the unix epoch time ( https://www.epochconverter.com/ ). Is it supposed to be the server parameter time (in this case, France)? I tried several different servers (i.e http://www.pool.ntp.org/zone

Im trying to detect when the module actually connects to my wifi AP, since .connect does not have a callback im doing something simple like this: wifi.sta.config("SSID","password") wifi.sta.connect() tmr.delay(1000000) i = 0 while(wifi.sta.status() ~= 5 and i < 10) do print("Waiting") print(wifi.sta.status()) i = i + 1 tmr.delay(1000000) end But the output of .sta.status() is always 1 inside the loop. When it finish, if I send the command =wifi.sta.status() manually from the IDE it tells me 5. Why? Using tmr.delay doesnot let run the event loop, you should use a timer callback. Then the code

I have built the ESP8266 SDK according to this document . But the compile report shows the error below. Attachemnt is the ld file. Would you please help me to resolve it?

通过ESP8266调节继电器时间 1、继电器选择（可调节时间的继电器） 2、继电器与esp8266的接线【set --- D6，UP --- D5，DOWN --- D1】 3、Arduino 程序 void changeTime(int change_type) { // 长按 SET 2s pinMode(D6, OUTPUT); digitalWrite(D6, LOW); delay(2300); digitalWrite(D6, HIGH); Serial.println("长按 SET 2s 。。。 "); pinMode(D6, INPUT); delay(800); // 按一下 SET pinMode(D6, OUTPUT); digitalWrite(D6, LOW); delay(200); digitalWrite(D6, HIGH); Serial.println("按一下 SET 。。。 "); pinMode(D6, INPUT); // 等 2s delay(4000); Serial.println("等 3s 。。。 "); // 按一下 UP if (change_type == 1) { pinMode(D5, OUTPUT); digitalWrite(D5, LOW); delay(200); digitalWrite(D5, HIGH)

Is it possible at all to use map with ESP8266 for Arduino package? Here is my code: #include <map> typedef std::map<int, int> Items; void setup() { Items items; items[2]=5; //items.emplace(4,5); } void loop() { } Here is compilation/linking erorrs: Arduino: 1.6.5 (Windows 8.1), Board: "Generic ESP8266 Module, Serial, 80 MHz, 40MHz, DIO, 115200, 512K (64K SPIFFS)" sketch_oct31a.cpp.o: In function `loop': C:\Program Files (x86)\Arduino/sketch_oct31a.ino:11: undefined reference to `std::_Rb_tree_insert_and_rebalance(bool, std::_Rb_tree_node_base*, std::_Rb_tree_node_base*, std::_Rb_tree_node_base

I have a raspberry pi 3 with raspbian stretch as its operating system. I have installed and fully configured a MQTT broker on the raspberry pi following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-install-and-secure-the-mosquitto-mqtt-messaging-broker-on-ubuntu-16-04 Everything works fine and well on the broker's side. The certificates get renewed after 60 days and you can only connect to port 1883 via the localhost and the other ports (8883 and 8083) are open but can only be accessed using TLS version 1.2 and for the latter also using websockets.
