OK- yes that's quite a trip! Interestingly though, when the Arduino IDE's serial monitor pops up, the default rate is 300 baud ?! So that's why I chose it for the Serial call and as far as the bridge, I thought you had said that I should call out some baud, but it doesn't really matter since I'm using an underlying Leonardo board- but I had seen someplace else online where they recommended 115,200 so that's what I used. Oh well...let me try nothing for the Bridge begin call and 9600 for the serial call and I'll report back...
