Hello, I am surfing trying to figure out if i can wire up a device to talk serially to the uArm control board.
I would ideally like to be able to communicate ttl rs232 using the bluetooth header, but it seems to me that these same pins (rx/tx) are used during usb-to-serial communication.
What i would like to do is use a second serial port, while keeping the main serial port alive.
Alternatively, i can limit my communication to one port at a time, but i would think if i plug in a ttl 232 device into the bluetooth connector, it will interfere with the usb-serial ftdi interface…their would be contention i suspect.
when someone uses the bluetooth connector how do they disable the usb to serial converter ?
