We have a firmware implementing AT+KHTTPPOST and AT+ KHTTPHEADER to send requests to our server from the HL and we are now refactoring the firmware to start working with the RC series. The RC series have removed those two commands and now I am not sure how we should create an HTTP request as the AT commands manual is not very clear on that.
The RC series still implements KHTTPGET but we need to send POST requests and set custom headers. From what I understand +KHTTPCNX should return CONNECT (as it starts the HTTP connection) so that we could simply send our custom HTTP message from the MCU to the module but from reading the manual, KHTTPCNX just returns OK so it doesn’t enter data mode.
How should we send an HTTP POST message with custom headers from the RC series? (without having to use a raw TCP socket).
