Node.js convert hexadecimal number to byteArray
提问by GingerJim
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?
我想使用蓝牙连接发送原始缓冲区。内容是一个十六进制数。目前我手动将数字拆分为字节数组。是否有任何函数可以帮助我将数字转换为字节数组？
//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);

In new versions of node (6+) the new Buffer()interface is deprecated. Use:
在节点 (6+) 的新版本中，new Buffer()不推荐使用该接口。用：
Buffer.from("250001000192CD0000002F6D6E742F72", "hex")
instead.
反而。

new Buffer("250001000192CD0000002F6D6E742F72", "hex")
