I've read that the hardware serial is used by bluetooth on the Pi, is this what you mean?
No, it wasn't - I wasn't aware of that... Seems odd, but that would cause you some problems if it was true.
I guess perhaps software serial is an option for connecting Espruinos... You could always plug in one Espruino via USB, and then use Serial on that Espruino to talk to the others? USB-TTL adaptors would work too.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
