Subject: [beagleboard] Beaglebone Black running client/server using wireless
I'm running the client server example programs from Derek Molloy's fine book
(chapter 10). I've put the server on the beaglebone and the client on a
separate Linux PC.
Server code:ssint main(int argc, char *argv[]){ cout << "Starting EBB Server
Example" << endl; SocketServer server(54321); cout << "Listening for a
connection..." << endl; server.listen(); string rec = server.receive(1024);
cout << "Received from the client [" << rec << "]" << endl; string
message("The Server says thanks!"); cout << "Sending back [" << message <<
"]" << endl; server.send(message); cout << "End of EBB Server Example" <<
endl;}
Client Code:
int main(int argc, char *argv[]){ if(argc!=2){ cout << "Incorrect usage:
" << endl; cout << " client server_name" << endl; return 2; }
cout << "Starting EBB Client Example" << endl; SocketClient sc(argv[1],
54321); sc.connectToServer(); string message("Hello from the Client");
cout << "Sending [" << message << "]" << endl; sc.send(message); string rec
= sc.receive(1024); cout << "Received [" << rec << "]" << endl; cout <<
"End of EBB Client Example" << endl;}
The examples work great when I plug the BBB directly using the Ethernet port.
The client talks to the Ethernet port at 192.168.1.36.
I've also setup wireless to work on the BBB using an Edimax dongle. It shows up
at 192.168.1.38. If I run the client pointing to the wireless address it
doesn't work.
If I plug the Ethernet cable back into the BBB with the wireless dongle also
attached... the wireless address 192.168.1.38 now starts working with the
client. The wireless otherwise seems fine. I can ping & wget using just the
dongle attached (no Ethernet plugged in).
Any suggestions? Not sure how I would even debug this?
