I use petalinux 2017.2 to generate the system.
Wifi is ok but Bluetooth not work. I use the bt.sh.
#To turn on BT_REG_ON, which is on EMIO GPIO #0
echo 960 > /sys/class/gpio/export
./bt_ttys2.sh: line 7: echo: write error: Device or resource busy
echo out > /sys/class/gpio/gpio960/direction

#Set uart0 = serial1 = ttyPS1 baudrate:

sleep 1s
#For the flow control.
#It seems you have to send a character before RTS from the 1DX modulke will be set in the correct state.

sleep 1s
#Initialize the device:
