[Hilo] Do I need to set GPIO (AT+KGPIOCFG) before antenna detection <AT+KGSMAD=1,0,45,1,2>?
Answer: No. When you want to use antenna detection feature, you don’t need to set GPIO by yourself.
When you set <AT+KGSMAD=1,0,45,1,2>, module will configure GPIO1 as input and GPIO2 as output input automatically,
But please note GPIO may be already used by other features like +KSIMDET, +KJAMDET, +KSYNC, and +KTEMPMON.
