Simcom ответил на запрос согласно вот этого:

1. possibly error in libraries SIM900DevIDE - procedure of interrupt trap from signals
UART EVENT_SERIALSTATUS in manual,
and EVENT_SERAILSTATUS in fl_appinit.h.

2. In a document SIM900_Embedded AT Application Note_V1_0.pdf page 34 possibly error.
A "Type" is written FlTriggerType , in libraries this type is described as FlGpioTriggerType.

3. interrupt does not work from GPIO

2 > We will change the doc accordingly.
3 > For question3, please test beat version.
