I'm trying to concatenate some strings to send to an Arduino using an HC 05 bluetooth adapter. My question is for example, how can I add a newline character to the end of a string, using the block editor? Or, how could I add a specific ASCII character to a string? My Arduino is waiting for an EOF, or LF, or CR in order to process the string that I sent, but I can't figure out how to send any special characters using the App Inventor.
Any thoughts?. Thanks

A newline character is easy: just insert \n

For the rest, search this forum, there are enough threads discussing this.

Cheers, Ghica.
