I am trying to adapt an older piece of programming to allow it to run off a windows CE 5.0 piece of hardware rather then from a computer.
When the program starts it checks that all of its peripherals are connected by communicating along RS232 to a wireless module. When the program is run from the computer it sends out the initialise message, waits 200ms and then checks for a response. If the response is correct then the program continues, otherwise an error is produced.
Now for the problem, when the exact same message is sent windows CE controller no response is being detected and an error generated. I have checked that it is sending a message and that it can receive messages by connecting the controller to the computer and have been able to pass messages accurately back and forth between the two along RS232 but cannot determine why the controller cannot pass messages to the module.
Any suggestions or help would be greatly welcome.
