Hi,
I have gone through the article on dynamic ip connection, but so far i'm not able to establish communication with the meters and need help in same.
Problem statement : I have Energy meters with 4g connections, and need to establish connection with them as well as read data.
What i know so far : Meter will initiate the connection, meter uses security suite 0.
I have a tool to check incoming requests from meter and i can see request coming there, but when i run the code given in gurux dynamic ip connection article, it does not do anything, can you please guide me towards how can i establish connection and then read data from the meter.

Hi,
If believe that your meter is sending a push message after it establishes the connection for the server.
Can you establish the connection with RS-232 or an optical probe?
If you can, you need to check if the meter supports the auto-connect.

If auto-connect is not found from the association view, your meter can communicate only with static IP addresses.
If you want to use a dynamic IP address, your need to receive data from the push messages. You can use a push listener example to show received push messages. You need only change the listening port and block cipher and authentication keys if they are used.
