Since James developed the Python example for using the BLED112 bluetooth USB dongle on a windows PC and several folks have verified that set-up does in fact communicate between a windows PC and mooshimeter, would that be a good place to start? In other words, get the javascript code working on a windows PC with the BLED112 then migrate to other Bluetooth devices later ( or just keep using the BLED112). Would that work? —Duane
