How To

String bacnetMessage -> You need to find the HexString from an Datagram Packet. Bacnet2JsonExample

//Read hexString from UDP
String hexString = "810b00160120ffff00ff10080c000000001c"; //WhoIs message
String json = no.entra.bacnet.json.Bacnet2Json.hexStringToJson(backnetMessage);
// Result is
