• Thanks, that's handy to know though.

    Some other potential ideas:

    • You could just poke the data straight into Serial1 without having to get the RN2483 involved - I think just Serial1.emit('data','\r\n') should sort it.
    • Serial ports can forward framing errors to the code if configured to do so: http://www.espruino.com/Reference#l_Seri­al_setup - not sure of that helps you (I can't remember if adding framing errors stops the extra characters from being reported)
