Hello,
I try to connect with a landis E570 through optical interface. The connection seems OK, but the AARQ failed, the meter has a strange behaviour sending 2 frames AARE. Here are the details of the exchange.
The exchange was done without security, address 0x10.
17:58:11 Send SNRM request.

Hi,

Hi,

The meter is sending encrypted push messages. Do you have the block cipher and authentication keys so you can decrypt the data?

You don't need to establish the connection to the meter if you want only to receive push data.
Check push listener example how you can handle received data:

You need to set the correct block cipher and authentication keys so you can decrypt the received data.
BR,
Mikko
