Issue reading ISKRA MT880 from Arduino

Hi,

I try to read a meter MT880 with Arduino example code ,
but the sample program not working.

I think the issue is on init :

Assuming the default password is password

Client.init(true, 1, 172, DLMS_AUTHENTICATION_LOW, "password", DLMS_INTERFACE_TYPE_HDLC);

Using the Director to test, it works correctly by this entry :
COM3:9600:8None1 -c 1 -s 172 -a Low -P password

Is correct to use the 172 also in Arduino code ?

Best regards,
and thanks for any useful hint.

Hi,

Your settings look correct. If you can read your meter with a client example using those arguments, you can read your meter with Arduino if your serial port settings are correct. If you can't read the meter with Arduino can you add a hex trace here so I can compare the bytes?

Another question: is there a way to indicate -d Italy to indicate Italy standard
in client.ino code in Client.init ( .. ..... ) ?

Hi,

It looks like you have commented on AARQ and AARE messages. Your client is only sending SNRM and received UA messages, but don't send anything else. Check the reason for this.

-d Italy is used to show correct descriptions for the OBIS codes, but Arduino doesn't use that information for anything.
