First contact!

It took me about 30 minutes to write a simple socket server application in C# but it took me FOREVER (OK, about 4 hours) to figure out how to configure the WiFly to talk back using socket.  Then it took me another FOREVER(again, about 4 hours) to figure out how to make the commands I am sending from C# app thru WiFly to CAN232 and retrieve the CAN data back from CAN232.


How to configure the WiFly:
Following was done using WiFlyClient app on my iPad.
[Edit] Just found out this can also be done using Terminal app on Mac.  telnet 169.254.1.1 2000

1. $$$: put the WiFly into command mode 
2. set comm close 0 (that is number zero)  : stop the module sending status message when network connection is closed.
3. set comm open 0 (again, number zero): stop the module sending status message when network connection is open.
4. set uart mode 0x10 (hex 10): clear all waiting data if connection is closed
5. set uart baud 57600:  I have not tried it at 115200 but should work
6. set sys printlvl 0 (again, number zero): stop misc status messages being sent to RS232
7. set ip host ___.__.___ (my computer IP address here)
8. set ip remote_port ____ (this just has to match my C# port)
9. set sys autoconn 10
10. save
11. reboot
12. cycle the power on the WiFly

Commands to send from C# app to CAN232:

1. ""               // clear the buffer
2. "C"            // close CAN232 just in case it was left open from previous
3. "V"           // get CAN232 Version
4. "N"           // get CAN232 Serial
5. "S6"          // set the CAN bus speed to 500Kbit
6. "M48000400"     // set acceptance code register
7. "m31EFBBEF"  // set acceptance mask resister
8. "O"                     // open the CAN channel

Sample data retrieved from CAN232:
