This is not really a problem but something strange is going on.
When Create2 is connected to a PC via the USB original connector lead, when you start-up the computer the Create2 is activated by the Baud Rate Change (BRC) pulling to ground. If I understand correctly, normal behaviour.
My Create2 is connected to a XBEE via a buck converter, I added a switch so the buck converter and the XBEE should not drain the battery continuously so as mentioned in the specs.
I followed the Bluetooth pdf for the connections, its working well for sending commands but I still just have a few problems with streaming the return data but that will be resolved.
But now, with the XBEE switched off my Create2 still activates when I start-up my PC, how is that possible, how can the BRC be pulled to ground?
There can be no communication between the PC XB and the Create2 XB since the Create2 XB is switched off, only the PC XB is switched on when starting the computer.
Its not a problem, its just that I am puzzled. Can anyone explain why this is happening?
