Connect SIM5360 AWS server GET / POST calls
The sequence below is taken from the SIM5360 AT command manual, chapter 18.5.

Make sure you have good network by checking it from

AT+COPS?


Now we're going to use the Secure Hyper Text Transfer Protocol Service.
Start by sending

AT+CHTTPSSTART


wait for OK, then send

AT+CHTTPSOPSE="&lt;host&gt;",&lt;port&gt;[,&lt;server_type&gt;]


and wait for OK, then send

AT+CHTTPSSEND=&lt;len&gt;[,&lt;filename&gt;]


len is the length of request in bytes and filename is the name of the file you want the data to upload from.
After this command you will receive &gt;, now send your GET request

GET /xxxx.xxx
Host: xxx.xxxx.xxx    
User-Agent: curl/x.xx.x    
Content-Length: x


Once your request matches the length you specified, SIM5360 will send your data and return 

OK
+CHTTPS: RECV EVENT


indicating that the server responded. 
You can read the response by giving the command:

AT+CHTTPSRECV=&lt;len&gt;


The peer can close automatically depending upon the server, but if you want to close it manually then send

AT+CHTTPSCLSE


and you will receive

+CHTTPSNOTIFY: PEER CLOSED
OK


At this point, since the Secure HTTP Service is still running, you can send another GET request from AT+CHTTPSOPSE command.
But if you want to stop the service, you can send

AT+CHTTPSSTOP


and SIM5360 will correspondingly respond OK on success.



I used api.thingspeak.com server for GET request and the server responded as expected by "1". In my case the URL for the GET request is api.thingspeak.com/update?api_key=xxxxxxxxxxxxxxxxx&amp;field1=xx

Below is copied from my terminal:

AT+CHTTPSOPSE="api.thingspeak.com",80,1
OK

AT+CHTTPSSEND=122
&gt;GET /update?api_key=xxxxxxxxxxxxxxxxx&amp;field1=xx
Host: api.thingspeak.com
User-Agent: curl/7.45.0
Content-Length: 0    
OK
+CHTTPS: RECV EVENT
+CHTTPSNOTIFY: PEER CLOSED

AT+CHTTPSQECV=512
OK
+CHTTPSRECV: DATA,1
1
+CHTTPSRECV: 0


Hope this helps.
