To send data: byte [] arrSendData byte []=https://bbs.csdn.net/topics/new
X12 {0 x10, 0 x02, 0, 0 x00 to 0 xf8, 0 x00 to 0 x00 to 0 XFF, 0 XFF, 0 x03, 0 x00 to 0 x00 to 0 x01, 0 x04, 0 x00 to 0 x00 to 0 x40, 0 x1f, 0 x00 to 0 xa8, 0 x02, 0 x00 to 0 x10, 0 x03, 0 x31, 0 x39};
2. Use a serial port debug the received data

So the two do not match the data completely, this is what causes excuse me????????????????

3. I use a serial port debugging to send data: byte [] arrSendData=https://bbs.csdn.net/topics/new byte []
X12 {0 x10, 0 x02, 0, 0 x00 to 0 xf8, 0 x00 to 0 x00 to 0 XFF, 0 XFF, 0 x03, 0 x00 to 0 x00 to 0 x01, 0 x04, 0 x00 to 0 x00 to 0 x40, 0 x1f, 0 x00 to 0 xa8, 0 x02, 0 x00 to 0 x10, 0 x03, 0 x31, 0 x39};
4. Use a serial port debug the data received and sent the same,
So trouble great spirit action

1. Please make sure your parameters configuration is consistent (baud rate, parity, data bits, stop bit)
2. Please send your post code

CodePudding user response:

You have not set baud rate right, should be this reason, both sides to the same baud rate,

CodePudding user response:

See with ODD check for the first time, I have seen None and even,,,

CodePudding user response:

Found the reason, thank you

to ask a question, how to judge the data sent out, and accept, when you don't then receive returned to go wrong, and at least more than 1 second delay, have a faster way?
