Testing the Sensors board to use it in an Android OS.
UART1 is fine and act as the console. (Mentioned in another forum thread)
Send the data from the DragonBoard to the Arduino in the Sensors Board, UART0 is fine.
But if I try to open the UART0 (/dev/ttyHS0) in receive mode I set the RTS which reset my Arduino!
I know this is used to program the Arduino directly from the DragonBoard in Debian but what can we do if we just want to comunicate with the Arduino and not program the Arduino?
I set the parameters ($ stty -F /dev/tty96B0 -hupcl # Release ATMEGA from reset) as mentioned in the Debian example and this in fact release RTS but when I open the port with an Android App it RTS is back.
Any idea on how to remove this reset? If not possible could we place a jumper in a new Sensors board redesign to open this RTS connection?
NOTE: I also tested the output of the Arduino and my data are coming out OK in another external FTDI port.
BTW: to be able to use “stty” in Android I installed Busybox and this is fine.
