Hi masters!

How can I write in the remote address buffer and remote port to the Udp?
I would like to send data to a remote card using the Udp protocol.
I wrote the address and remote port value but the compiler does not accept these write values.
Udp.beginPacket(Udp.remoteIP(0xC0, 0xA8,0x00,0xB1), Udp.remotePort(8888));
** Udp.write(0x35); **
** Udp.endPacket();**
Observing by the WireShark the value of the destination ip and destination port is not written. How can I write the addresses in this address buffer?

Never post text output as images!

Udp.remoteIP() and Udp.remotePort() don't accept parameters, so don't expect that to compile.

Try something like this:

IPAddress remoteHost(0xC0, 0xA8, 0x00, 0x81);
Udp.beginPacket(remoteHost, 8888);
