Hi guys, I successfully installed standalone Thingspeak on Ubuntu. Unfortunatelly I'm stuck little bit just now. As a newbie I have been searching any usuable tips to upload data by enc28j60 into the local thngspk for last 3 days and - nothing usuable. Every sketch for enc28j60 with ethercard library I've found contains definition of server like this: const char website PROGMEM = "api.thingspeak.com"; (for example here) I need to replace this domain address by IP local 192.168.0.159:3000. A plain substitution of text in brackets doesn't work. Could anybody suggest me any hint at least? How and where shall I change a mentioned code described on the hyperlink? Eventually, this joined sketch for ESP8266 with AT comands is workable - hence I'm sure the local server is OK. Thank you very much Tom . . . String password = "xxxxx"; // hidden #define IP "192.168.0.159" // IP address of thingspeak.com String GET = "GET /update?key=xxxxxT"; // hidden . . . String cmd = "AT+CIPSTART=\"TCP\",\""; cmd += IP; cmd += "\",3000"; esp8266Module.println(cmd); Serial.println(cmd); delay(5000); if(esp8266Module.find("Error")){ if(DEBUG){ Serial.println("ERROR while SENDING"); } return; } cmd = GET + "&field1=" + voltage1 + "&field2=" + voltage2 + "&field3=" + voltage3 + "&field4=" + voltage4 + "\r\n"; esp8266Module.print("AT+CIPSEND="); esp8266Module.println(cmd.length()); delay(15000); if(esp8266Module.find(">")) { esp8266Module.print(cmd); if(DEBUG){ Serial.println("Data sent"); } }else { esp8266Module.println("AT+CIPCLOSE"); if(DEBUG){ Serial.println("Connection closed"); } }
