Objective: The DTU-H100 module converts RS232 data into HTTP headers and sends it to a HTTP server as documented.
Setup: PC Terminal Emulation > USB-to-RS232 Cable > DTU-H100 IOT Module (in HTTPD Mode) > Internet > Apache Server (LAMP Configuration hosted in Droplet)
Problem Statement: HTTP statements from DTU-H100 module are rejected by apache with code 400 (see dumps). If I make the same requests with HTTP request emulator on my browser and the same headers and payload, they are accepted with code 200.
All other documentation is in the attachment. Bids without having read the specifications with be rejected immediately. Don't even bid.
