/ On many platforms USBTX/USBRX overlap with serial on D1/D0 pins and enabling the below will interrupt the communication.

• You can use an LCD display to print the values or store them on an SD card etc.
• / Serial pc(USBTX, USBRX);

/**

• D1 - TX pin (RX on the GSM module side)
• D0 - RX pin (TX on the GSM module side)
• 19200 - GSM baud rate
• / GSM gsm(p9, p10, 19200, PHONE_NUMBER);

void messageHandle(void) { disable_irq(); int messageType = gsm.loopHandle(); if(MESSAGE_RING == messageType) { gsm.answer(); } else if(MESSAGE_SMS == messageType) { char smsMessage[SMS_MAX_LENGTH]; gsm.getSMS(smsMessage); } enable_irq(); }

int main(void) { while(0 != gsm.init()) { wait(2); }
