OscP5 between pc and Mac
Sep 4th, 2008, 7:25pm  
I'm experiencing problems with communication between a Mac as a Broadcaster and a pc as a client. The sketch I made worked fine with two Macs. Does anyone know if its possible to receive data from a pc, working from a Mac? Or am I doing something wrong?

is the machine you are sending messages from connected to a network according to the ip 169.254.55.21 as seen in the log it doesnt seem so.

"When you boot your machine, the computer will broadcast a request for an IP address and the router will normally answer. If it does not see the DHCP server it will give up and make up an IP address for itself. This IP will often look something like 169.x.x.x. This is a local address that will not likely have any communication with other PCs on the network." from pctechbytes

more things to check:
did you check the firewall settings of your pc maybe the port you want to send osc messages to is blocked are you sending to the right ip address, the ip address of your pc

Thnx for the reply. But I think there might be a misunderstanding, I'm not trying to connect to the internet, its just a Local Area Network I'm using. I connected my Mac with a plain internet cable to a pc. So I probably need a local IP address.
I'm using your examples from the oscP5 library to do the tests. The broadcaster sketch is open on my Mac and the broadcastclient runs on my pc. My last post was the log I got from my pc, the broadcastclient.

So normally there are no problems between Mac and pc for this issue?

This is what the broadcaster says (the server/Mac)
