You don't need to run the script every time with sudo as suggested in the comments but you need to make sure that you have read/write permissions for /dev/ttyAMA0. You can modify the permisions using:



sudo chmod 666 /dev/ttyAMA0


If the device is detachable, you may also consider creating an udev rule which will apply correct permissions each time you connect it. You can read more about udev rules at Debian's wiki.
