B4R Question Ethernet UDP cable disconnect

SendPacket will return false if it failed to send the packet. This will happen when the network is not connected.

Thank you for your answer
I suppose if the cable is disconnect and reconnect
So long the arduino does not send UDP packet
the arduino is not able to receive UDP packet from the PC.
So the good way is to send a UDP packet as a watchdog.
So i can use the FALSE return from the SendPacket
for retry the connection ( ethernet and udp, or only udp ? )
Best regards

SendPacket is relevant to UDP communication. With TCP it is different, you use AsyncStreams and handle the Error event.
