• Tunable antenna pin function of GPIOs correspond to ALT16,17
function of the GPIOs, so it should also set which GPIO will used as
ALT16,17 function through AT#GPIO command. Access those GPIOs
through AT#GPIO command while Tunable antenna function is
enabled is not recommended.
• First, GPIOs what you want to use should set through #GPIO
command before #STUNEANT command setting.
In stuneant "enable" state, tunable antenna gpio cannot be set via
GPIO command.
