Hi, I am trying to download a file from my webserver with a POST request, but the module becomes unresponsive. Can the following sequence of commands be used to get a file from a webserver? AT+KTCPCFG=1,0,[url.com](http://url.com),80 AT+KTCPCNX=1 AT+KTCPSND=1,SIZE POST /test HTTP/1.1 Host: foo.example Content-Type: application/x-www-form-urlencoded Content-Length: 27 var=filename.txt \r\n\r\n +++ AT+KTCPRCV=1,500 AT+KTCPCLOSE=1,1 ---

You should use http GET operation, not POST Have you tried +khttpget command? ---

Hi, thank you for your response. Do you have the same example with a POST request. My web application will send a file in response to a POST request. ---

Hi, Thank you for your help again. I send the following commands to the modem: Sent commnd: ‘AT+KHTTPCFG=1,“[web.pythonanywhere.com](http://web.pythonanywhere.com)”,80,1\r’ Rspnse: ‘AT+KHTTPCFG=1,“[web.pythonanywhere.com](http://web.pythonanywhere.com)”,80,1\r\r\n’ Rspnse: ‘+KHTTPCFG: 1\r\n’ Rspnse: ‘OK\r\n’ Sent commnd: ‘AT+KHTTPHEADER=1\r’ Rspnse: ‘+KCNX\_IND: 1,4,1\r\n’ Rspnse: ‘+KCNX\_IND: 1,1,0\r\n’ Rspnse: ‘+KHTTP\_IND: 1,1\r\n’ Rspnse: ‘AT+KHTTPHEADER=1\r\r\n’ Rspnse: ‘CONNECT\r\n’ Content-Type: application/x-www-form-urlencoded" Context-Length: ContentLength +++ I get no response from the modem after that. Can you help me with the issue? ---

You mean it stuck in data mode? Did you send --EOF–Pattern-- to indicate it is end of data pattern? Btw, why did you send content length for twice? ---

Hi, Yes, I don’t get an “OK” from the modem. Do I need to send “–EOF–Pattern–” as a literal string or a “+++” string to indicate EOF? ContentLength is a variable that holds a numeric value (22 for example) ---
