Is it possible to make the script run when it shifts from normal mode to the interactive mode.
#/bash/bin
sudo gatttool -b 80:EA:CA:00:00:03 -I
# All these commands are typed in interactive mode
connect
while [ 1 ]; do
char_read_hnd 0x0030 > a.txt
done
exit 1

expect scripting language, or perl's Expect.pm module or python's pexpect. Other languages also have similar expect-like libraries.
If you need just write or read you can use one string command like this:
gatttool -i hci0 -b device=MAC --char-write-req -a handle=0x0001 -n value=0x0001
gatttool -i hci0 -b device=MAC --char-read -a handle=0x0001
I found it here: http://www.mathieupassenaud.fr/control-your-plugs-with-bluetooth-and-bash-scripts/.
To find more options see gatttool --help-all.
You can use expect for shell or pexpect for python.
