I want to send a raw buffer using bluetooth connection. The content is a hex number. Currently I split the number manually to an byte array. Is there any function that can help me convert the number to byte array?

//var data = 0x250001000192CD0000002F6D6E742F72;
var data = new Buffer([0x25,0x00,0x01,0x00,0x01,0x92,0xCD,0x00,0x00,0x00,0x2F,0x6D,0x6E,0x74,0x2F,0x72]);
serialPort.write(data);

在新版本的节点（6+）中，该new Buffer()接口已被弃用。利用：

Buffer.from("250001000192CD0000002F6D6E742F72", "hex")

反而。
