I'm working on LPC2468 using Keil bundle package ( MDK / RL ) I want to design a windows form ( GUI application ) in Visual C++ to perform communication ( send and receive information ) between computer and microcontroller ( LPC2468 ) I'm suggested to use SNMP v3 for this project. However I need both SNMP v3 manager and agent source code which is about $20,000. I figured out I can communicate with my board using Telnet also. However Im not sure if it's a standard way to do that. I'm just wondering if you have any suggestion what protocol might be good for this application.
