this is the Code portion :
Serial.println(“Begin receive packet from api.thingspeak.com!”);
ping_at(“AT+QPING=1,“api.thingspeak.com””);
Serial.println(“connecting to server”);
bg77_at("AT+CEREG?",1000);//Confirm that the network access is successful.
// bg77_at(“AT+QICFG=“dataformat””,1000); //set dataformat to send data
bg77_at("AT+QIDEACT=1",1000);
bg77_at("AT+QIACT=1",1000);
bg77_at("AT+QIACT?",1000);
bg77_at("AT+QHTTPCFG=\"contextid\",1",1000);
bg77_at("AT+QSSLCFG=\"sslctxid\"",1000);
// bg77_at(“AT+QIOPEN=1,0,“TCP”,“api.thingspeak.com”,80,0,0”,6000);
Serial.println(“Starting to send data to server”);
bg77_at("AT+QHTTPURL=75,30",8000);
// bg77_at(“CONNECT”,1000);
bg77_at(“https://api.thingspeak.com/update?api_key=ZXCZJ7IERO0F0GAZ&field2=49”,100);
bg77_at(“AT+QHTTPGET=20”,1000);
When i run the command at the end of sequence “AT+QHTTPGET=20” means send get request
i get this error >> +CME ERROR: 711
some suggest ?
thank you in advance
