Control SMS incoming

The Hydro Logger H40G does not contain any relays, therefore, unlike the H7 or M4016-
G3, the number of control SMS is severely limited. In fact, it is only a command to im-
mediately send the measured data to a server on the Internet.
This command is usually used to immediately rebuild parameters according to a new
parameter file on the server.

HESLO,DIAL0

After receiving this command, the measured data is immedi-
ately transferred to the server via the GPRS network and, if
necessary, a new parameter file is downloaded from the server
to the device (no waiting for a regular data session).

The stations have built-in two-level security against misuse of control commands by an
unauthorized person.
The first level of protection consists in the presence of a HESLA, which must be used to
start every command message. The password can be any sequence of up to 12 char-
acters, separated from subsequent commands by a comma.
Another  configurable  condition  for  executing  the  command  is  that  the  phone  number
from which the control message was received is present in the list of stations with SMS
reception enabled (if the option "Receive messages only from senders in the list" is set
in the basic GSM parameters window).

In this case, the phone number must also be

listed with the country identification, i.e. for the Czech Republic with the prefix
+420.

The station responds to command SMS messages with a confirmation SMS message
that the command has been received and is understandable. If this confirmation SMS is
not to be sent, the special command NA (No Answer) must be included anywhere in the
text of the control SMS.
