I would prefer to use the AtWiFi library.
But, AT commands I used with a SIM800 module.
Below is an update function which sends data to Thingspeak “GET https://xxx.xxx.xxx.xxx/update?xxxxxxx&field1=25.5”. Is there a similar way to do this for WIO600 lite?
</s>void sendUpdate()
{
if (DEBUG) Serial.println("Prepare Connection to Thingspeak...");
SIM800_Serial.println("at+csq");
delay(minZ);
getResponse();
SIM800_Serial.println("at+cipshut");
delay(maxZ);
getResponse();
SIM800_Serial.println("at+cstt=\""+ APN +"\",\"\",\"\"");
getResponse();
SIM800_Serial.println("at+ciicr");//start wireless connection cellular network
getResponse();
SIM800_Serial.println("at+cifsr");//enquire regarding the IP address allocated
getResponse();
SIM800_Serial.println("at+cipstart=\"TCP\",\""+ URL +"\",\"80\""); //connect to the ThingSpeak update URL (https://api.thingspeak.com)
getResponse();
SIM800_Serial.println("at+cipsend=80");//declare the number of bytes (characters) I want to send
getResponse();
SIM800_Serial.print("GET https://"); //this is a constant beginning for the GET command and is as provided by ThingSpeak
SIM800_Serial.print(URL);
SIM800_Serial.print("/update?");
SIM800_Serial.print(APIKEY); //the channel API key provided by ThingSpeak
getResponse();
SIM800_Serial.print("&field1=");
getResponse();
SIM800_Serial.println(String(temp));//the value to post to field
getResponse();
SIM800_Serial.println("at+cipack");//ask for acknowledge details
getResponse();
SIM800_Serial.println("at+cipclose");//close the IP connection
getResponse();
