The javascript-json hexadecimal format is converted to a string.

{Code ...} {code ...} {code ...} {code ...} the code above refers to the hexadecimal code obtained through PHP conversion. However, when JavaScript gets the code, it has become a string and you want to convert cmd to the hexadecimal Blue part like cmd1 for the desired effect. red indicates the data content.

var cmd = ["0x02,0x03,0xB4,0xB4,0x00,0x06","0x00,0x02,0x6E,0x00,0x00,0x05","0x01,0x01,0x00,0x78,0x00,0x05","0x03,0x03,0x82,0x96,0x00,0x05"];

var cmd1=[0x02, 0x03, 0xB4, 0xB4, 0xFF, 0xFF,0x02, 0x03, 0xB4, 0xB4, 0x00, 0x06,0x00, 0x02, 0x6E, 0x00, 0x00, 0x05,0x01, 0x01, 0x00, 0x78, 0x00, 0x05,0x03, 0x03, 0x82, 0x96, 0x00, 0x05];

var test =["0x02,0x03,0xB4,0xB4,0x00,0x06","0x00,0x02,0x6E,0x00,0x00,0x05","0x01,0x01,0x00,0x78,0x00,0x05","0x03,0x03,0x82,0x96,0x00,0x05"];

var cloud = [0x02, 0x03, 0xB4, 0xB4, 0xFF, 0xFF,    0x02, 0x03, 0xB4, 0xB4, 0x00, 0x06,    0x00, 0x02, 0x6E, 0x00, 0x00, 0x05,    0x01, 0x01, 0x00, 0x78, 0x00, 0x05,    0x03, 0x03, 0x82, 0x96, 0x00, 0x05];

Code above

Cmd is a hexadecimal code obtained through PHP Conversion. However, when JavaScript is obtained, it has become a string.
To convert cmd to the hexadecimal blue part of cmd1, the desired result is red, which is the data content.
