Hi, I am new to this ESP8266.com site and I thought I had posted a message yesterday but I do not know how to verify if it was really posted and answered. Can you educate me on how the forum works and what I may have done incorrectly? Thank you

OK, I see that I am the only one in the chat room and the session will end in a few minutes. So I may check another day. Thank you

Has someone any idea?

i am looking for firmware of the esp8266 01 boards - the original ones. any assistance and/or pointers welcome.

Hi everyone… I am able to successfully connect to owncloud from my esp device making http/https request using webdav and also able to download and upload files. But the problem is i am unable to create new folder directly from the esp. when i give new folder path in url it returns the answer which is logical that path does not exist. But i was hoping as i am able to create new file name similar way i could also create new folder. Any help will be appreciated i can share the code upon request. i am using arduino ide and c language.

hi i am calling webdav library url e.g http://ip/remote.php/webdav/folder below is my code for uploading a file in my cloud…

#include <ESP8266WiFi.h> #include <ESP8266HTTPClient.h> #include <FS.h> #include <ArduinoJson.h> #define FILE “/testfile8.json” //file which i want to create const char* ssid = “ssid”; // network ssid const char* password = “pass”; // network passphrase const char* apiUrl = “http://ip/remote.php/webdav/testproject” FILE; /testproject folder already exists but when i give new path e.g testproject/testfolder which does not exist but i was hoping it will be automatically created as http creates new file too/

HTTPClient http; http.addHeader("Content-Type", "application/json"); http.addHeader("Content-Length", String(f_size, DEC)); http.setAuthorization(username,token); http.begin(apiUrl); int http_code; const auto A = millis(); http_code = http.sendRequest("PUT", &f, f_size); DBG.printf("\n time-keep: %lus", (millis() - A) / 1000); http.writeToStream(&DBG); http.end(); f.close();
