duo2 IOT-BOX GPIO command to turn on GSM

Moderators: chensy, FATechsupport

it seems that the GSM is always off by default
from the default sim800c-test.py
we can find that the GSM_PWR is pin 11 and LED is pin 9
what command do i use from WiringNP to turn it on ?

i tried
gpio MODE 11 IN
gpio MODE 9 OUT

but nothing change when i use gpio readall to check
what GPIO command should i use ?
found the answer
to turn on the modem use sudo/root
gpio mode 16 out
gpio write 16 1
