Hello.

We are having issues connecting to Ensor eRS801 meter over HDLC.
When sending SNRM, we get the following:

==> 7EA0070303938C117E
<== 7EA01F03022373C371818012050180060180070400000001080400000001533B7E

If we ignore this and continue to try to open association, we get the following:
==>7EA0440303106594E6E6006036A1090607608574050801018A0207808B0760857405080201AC0A80083132333435363738BE10040E01000000065F1F0400103F3DFFFF4CDF7E

<==7EA02E03022330C9DEE6E700611FA109060760857405080101A203020101A305A103020101BE0604040E010604EE667E

Also, when sending requests to meter, it always waits untill timeout expires and then we get the PDU.

Can you help us with that?
Thank you.

Hi,

Try to change the meter address from 0x1 to 0x91. 0x91 is the address what the meter returns.
