Common Mistakes
• Carriage return – some programs do not require the carriage return where as other will not work unless sent directly after the string. In the
case of some Terminal software the token <CR> is used to execute a carriage return. Depending on the program you are using this token
maybe different. Some other examples that other control systems deploy include \r or 0D (in hex)
• Spaces – Blustream commands do not require space between commands unless specified. There may be some programs that require spacing
in order to work.
- How the string should look is as follows OUTFR03
- How the string may look if spaces are required: OUT{Space}FR{Space}03
• Baud rate or other serial protocol settings not correct - see above
