Due to hardware requirements, if GSM/GPRS is powered down it must remain down for
at least 15 seconds before being powered up again.
The message packet should not be freed by the application; this is done by the
foundation code.
14.19 POSITION_FIX
The GPS engine has just completed a position fix and the information is available. The
parameter indicates which Sensor Table was used. In the current implementation, the parameter
passed to GPS_read should always be zero, and the parameter returned on a POSITION_FIX
event should always be zero.
14.20 POWER_ON
This event occurs after reboot regardless of the cause of the power on/reset. It is the first event
generated unless the power on was due to a wakeup timer. In that case, the TIMER event is the
first event generated, followed by the POWER_ON event.
Application code executed after the POWER_ON event should perform initialization such as starting
the appropriate network functions. A GPS read with a parameter of 0 is usually requested at the
end of the initialization sequence.
For more information, consult the SYS_powerDown description in the Application Programming
Interface (API).
14.21 RX_MTS_PKT
An ORBCOMM OSI protocol packet was received from a serial port. The parameter indicates the
type of packet received. Do not free the packet, as this is done by the caller.
14.22 RX_SER_PKT
A serial packet was received. The data are passed to the application as a message parameter,
along with the length of the string. The string is null terminated and can be displayed in a
printf() statement. The second byte of the message data indicates the type of packet
received, either modem terminated (0x0C), User Command (0x0D) or ORBCOMM Globalgram
(0x0E). For Iridium, raw data have been received.
14.23 SAT_IN_VIEW
The satellite-in-view status has changed. If the parameter [0-1] is zero, it indicates a satellite has
gone out of view; if one, it indicates a satellite has come into view.
14.24 SHUTDOWN
System is shutting down; save the configuration parameters and exit.
