configure:
Configured according to the table it will be sent every minute that contains the actual data retention
0xFE online package. Of course, if the user equipment has made next data in the case of every minute to
DTU, DTU will not send the line to maintain the package, because the user data has played a role in
maintaining online. Furthermore, DTU at the beginning of the data center is connected, or will send up a
registration packet.
This is the recommended way.

Of course, if users find the heartbeat packet transmitted 0xFE DTU can interfere with normal
communication, you can use the following configuration:
However, this configuration has a very important point, is that the user equipment needs within every
300 seconds and to send data to the DTU, content is not limited. Otherwise DTU After 300 seconds, it will
reconnect to the server to ensure the DTU is always online. When DTU reconnects with an interval of time
(about 30-60 seconds), if the user equipment within this interval, send data to DTU, these data will be
discarded. Therefore, in this configuration, a trial, it is preferable to ensure that the user equipment within
fixed every 300 seconds, the data is transmitted at least once (in order to avoid errors, preferably within
every 250 seconds on at least one occasion to DTU data) to DTU.
Another configuration is as follows:

Born this way, but also to send a heartbeat packet DTU can interfere with normal communications
users find an alternative, the parameters as follows:
