Title: Re: Receive UDP broadcast packets with OTRcvUData
|
I still cannot send myUDP broadcast. This is really
strange.
I send it on the subnet broadcast adress:
2.255.255.255 (ip mask 255.0.0.0)
I create a Synchrone socket and set it non
blockling. It receives broadcast on 2.255.255.255.
Sometimes I have to answer by broadcast and I
get the error
kEACCESErr |
-3212 |
Permission
denied |
when calling OTSndUData. If I send packets to a
specific machine, it works, but not broadcast.
I successfully set the IP_BROADCAST option to my
socket (no error & status == T_SUCCESS).
I tried setting this option before & after
binding the socket.
The socket is bind to
kOTAnyInetAdress.
The FireWall is off.
Thanks for your help.

IIRC you have to send to the /subnet/ broadcast address. That is,
if you're IP is 1.2.3.4 and your subnet mask is 255.255.0.0, you have to send
your packet to 1.2.255.255.
