SMS COMMAND LIST
Read chapter 5.11 to know how to construct a proper SMS message and send it to FM1120
device. All commands are case sensitive. While FM1120 operates in Deep Sleep mode and user
tries to send SMS message it cannot arrive to FM1120 device, because GSM/GPRS module is
disabled most of the time (wake up depends on Send Period parameter). FM1120 will receive
the SMS when it wakes up (exits deep sleep mode).
