GPRSCONNALIGN [align]
alignment of calls in seconds (default: 0, i.e. 00:00 =
midnight)
GPRSCONNINT [interval]
interval in seconds between two connection attempts
(default: 3600)
GPRSSECRET [secret]
this 32-bit integer (0 -4294967295) has to be set for
the RA440 and the gateway; this is a shared "secret" or
password
GPRSTMOUT [interval]
idle timeout in seconds (default: 3600); connections
that are idle this long will be terminated by the RA440
Set these parameters according to the needs of your application. Make
sure you choose the proper parameters for GPRSTMOUT (to allow for
appropriate idle times, but not ones that are too long),
GPRSCONNALIGN, and GPRSCONNINT (for specifying the proper
connect times of the RTU). Also take into account that the RA440 will
be polled for data requests by the Adcon Telemetry Gateway within
the GPRSTMOUT time.
After entering all parameters correctly, you can check your settings at
any time by entering the GSMSTAT command again. With the GPRS
parameters set, the response will be similar to the following:
