Java String and Hex character representation
提问by lulu88
I am trying to send a square bracket to a phone using logica smpp 1.3.7. I use dataCodingSetting of 3 - as per the network I asked about this. They advised that I need to package my message as below:
我正在尝试使用 logica smpp 1.3.7 向手机发送方括号。我使用 3 的 dataCodingSetting - 根据我询问的网络。他们建议我需要按如下方式打包我的消息：
You want to send ASCII Send the following
Character Decimal Hex Character Hex Decimal
[ 91 5B <ESC>< 1B 3C 27 60
My question is, I have no clue what this character is: ESC < And if I put just the Hex value of 1B 3C it comes out on the phone as exactly that: 1B 3C
我的问题是，我不知道这个字符是什么： ESC < 如果我只输入 1B 3C 的十六进制值，它会在电话上准确显示：1B 3C

I guess they want a String containing the bytes 0x1b and 0x3c so :
我猜他们想要一个包含字节 0x1b 和 0x3c 的字符串，所以：
sm.setShortMessage(new String(new byte[] { 0x1b, 0x3c }));
