I want to Position my bluetoothmodul, a little bit far away from the Ardoino Pro Mini. Cause I need also Connection from my roof garden.
For that there need to be a cable over about 7m with +/-/RX/TX. The Voltage drop isn't a Problem, but I thought the RX and TX cable maybe reduce the Speed (that woudnt be a problem for me) or even cut the communication( that woud be a Problem).
Are there People who already tried it? Which cable shoud be better for data: a thick one or thin ?
I hope you can understand me. :/
