I’m a beginner to c++ for esp8266 / platformIO. I’d like to put some initializations and declararions for a websockets-Server class into an .h / .ccp file, so I can reuse this module in future without putting all the code into my main.cpp file. But I’m running into initialzation errors, no matter which way I ..
I’m trying to build a feeder machine on a pig farm by using the Infrared photoelectric switch Sensor E18-D80NK to control relay then send notifications to line and mqtt broker when it’s working. I have been testing for 2 days, it’s working normal, but third day, it’s not responding then I just press reset so ..
i have an ESP and sending data to a C++ Terminalprogram to my PC. I need a transmissionspeed of at least 100packets per second. Right now I am only receiving 1000packets per 60s -> 16-17 Packets per second. Network Setup ist a Socket connection: ESP-Server, Terminal-Client, Transmissionprotokoll->TCP/IP TCP/IP is necessary! No UDP! Nagle is already ..
this is a theoretical question. I am doing a project right now where I get Sensordata every 10ms and send them to Matlab via TCP over Wifi. Its working but its unstable.That means im senind 4 bytes at one time but sometimes it send 24 bytes or 40 bytes at one time and sometimes the ..
I’am trying to iterate over a nested JSON-Object which i get as a HTTP-GET Response from my Hue-Bridge. The Response is something like this: { "name": "ViKo", "type": "GroupScene", "group": "2", "lights": [ "1", "2", "6", "9", "11", "17", "18" ], "recycle": false, "locked": false, "picture": "", "version": 2, "lightstates": { "1": { "on": false, ..
I’m working in garage door project and my desire is to implement some codes in sinric-pro garage door example to allow me to input the wifi, password, app key, app secret and garage door ID all through a web page so the Same code can be installed in multiple esp8266 and the variables can be ..
I use example of mDNSResolver library to resolve a local Host name to IP address . It work as i expect But when i change resolve object to a pointer as follow, the program can’t resolve any local host name anymore. #include <ESP8266WiFi.h> #include <WiFiUdp.h> #include <mDNSResolver.h> #include <WiFiClient.h> #define WIFI_AP "myap" #define WIFI_PASS "mypass" ..

I’m codding for Arduino (ESP8266), and have to read a string from a file, to use it. I don’t know how long is that file, so I have to create a char* and pass it to the readConf function so that malloc decides for the memory size. void readConf(char path[], char **buff){ SPIFFS.begin(); if (SPIFFS.exists(path)) ..
