Here is my setup that already works:
- bluetooth on PC connected to bluetooth on robot
- after connected, sparkfun bluetooth LED turns red
- I push a keyboard button, robot does stuff
Now since my cellphone has bluetooth too, why can't my cellphone control my robot? But it isn't working . . .
So I turn on bluetooth on my cell, detect the SparkFun bluetooth correctly, and enter the password 'default'. It correctly connects, at least on the cell phone side.
However there are two problems . . . the sparkfun LED doesn't turn red . . . and how the heck do I transmit simple text to bluetooth on a cell phone? I mean, I don't want to send random pics to my robot . . . my cellphone is a Nokia 2600.
I wonder if cellphones have HyperTerminal?
