arduino - Using Arduino GSM library to switch on IComSat GSM board

Question

I program my IComSat board attached to an Arduino Uno. It works, but the Icomsat module needs to be switched on by hand and I want to do that in software.

I using GSM_GPRS_IDE100_v309.zip

I using:

digitalWrite(GSM_ON, HIGH);
delay(300); /* spec says 200 should suffice */
digitalWrite(GSM_ON, LOW);

which is supposed to work.

Answer 1

您想查看 GSM.h 文件。默认情况下，GSM_ON 定义为引脚 8，GSM_RESET 定义为引脚 9，但对于 IComSat，情况不同：

#define GSM_ON       9 
#define GSM_RESET    8

您可以在原理图（http://www.komputer.de/wordpress/wp-content/uploads/2012/02/sch-icomsat-v1.1.pdf）第 2 页上看到：PERKEY 和 D9 已连接，RESET和 D8
