page 135/339ReferenceNotes• is set to LOW when antenna is connected. Otherwise set to HIGH• If the antenna detection algorithm detects a change in the antenna status themodule is notified by URC +KGSMAD: :0 - antenna connected.1 - antenna connector short circuited to ground.2 - antenna connector short circuited to power.3 - antenna not detected (open).• Instantaneous activation doesn’t affect a periodic activation eventually startedbefore• Be aware that if GPIO 6, 7, 8 are used no debug traces can be used.• For +KSIMDET, +KSYNC, +KTEMPMON, +KGSMAD, when they were enabled,they all will use GPIO as their output/ input pin; +CME ERROR: 3 will be issued toavoid conflict, when any two commands try to share the same GPIO pin.• Do not use +KGPIOCFG or +KGPIO to control the GPIO pin, when this pin hasbeen used by +KSIMDET, +KSYNC, +KTEMPMON, +KGSMAD. Thesecommands can manage the GPIO pin by themselves.Note d’étude / Technical document :URD1– OTL 5635.1– 008 / 70248 Edition 07AT Command Set for SAGEM HiLo/HiLoNC Modules24/06/2009
