On android is already implementet VT100 text terminal, as a common prompter witch can send parameters to software using blue tooth.
see link http://www.androidzoom.com/android_a...term_mgzm.html
The on field programming would look like this on your phone:
Yaw p = 14
Pitch I = 0.030
Pitch P = 8
calibrate giro
calibrate acc
set baro (aux1,0,0,1)
set level (aux1, 0,1,1)
set magneto (aux2,0,0,1)
list
reboot
etc...
The only update for this alternative consist in multiwii software to implement tty protocol vt100.
