The presence of two interfaces allows you to simultaneously use the first device (<code>/dev/ttyGSM</code>) to send AT-commands (to know the level of the cellular signal, send SMS, USSD-balance request etc) through minicom or gammu programs, and the second is (<code>/dev/ttyACM0</code>) for network communication. | The presence of two interfaces allows you to simultaneously use the first device (<code>/dev/ttyGSM</code>) to send AT-commands (to know the level of the cellular signal, send SMS, USSD-balance request etc) through minicom or gammu programs, and the second is (<code>/dev/ttyACM0</code>) for network communication. | ||
hardware control in the controller is represented by turning on/off the modem through its PWRKEY input, the state of which is controlled by one of the GPIOs of the processor. For the user, the modem power management interface provides the command <code>wb-gsm</code> with the options on, off, reset, restart_if_broken. | |||
