Hello,

There is no native support for UDP sockets in q, so you need to create a socket in C and then bind that to q. Once you have a socket, you can then serialize the data using .protobufkdb.serializeArray, with the data, to get a byte buffer. That byte buffer can then be sent on the UDP socket either as uni or multicast.

Many Thanks
