Issue Connecting Smart Meter via Optical Probe on Android (Invalid Logical Name / Limited Data Issue)

Gurux DLMS for Android

Hi Gurux Team,

I am trying to connect a smart meter using an optical probe with an Android phone

through the Gurux DLMS Android App.

Case 1 (Error: Invalid Logical Name)

When I configure the connection with these parameters:

Manufacturer: India Standard

Referencing: Logical Name

Interface: HDLC

Password: [Provided]

Wait Time: 30:00

Address Type: Default

Physical Address: 1

Logical Address: 0

Authentication: US

Client Address: 48 / 16 / 30

Security Policy: Authentication + Encryption

Suite: 0

Block Cipher Key: [Provided]

Authentication Key: [Provided]

Client System Title: [Provided]

I receive the error:
Invalid logical name

Case 2 (Successful Connection but Limited Data)

When I use these parameters instead:

Manufacturer: India Standard

Referencing: Logical Name

Interface: HDLC

Authentication: PC

Password: [Provided]

Wait Time: 30:00

Address Type: Default

Physical Address: 1

Logical Address: 0

Client Address: 16

Security Policy: None

Suite: 0

Block Cipher Key: [Provided]

Authentication Key: [Provided]

Client System Title: [Provided]

The app connects to the meter, but I only get limited data. I would like to retrieve additional datasets.

My Questions :

Why does Case 1 fail with Invalid Logical Name, while Case 2 connects but with limited data?

How can I configure the Gurux DLMS Android App to access all available meter data?

Do I need to fill in the following fields for my use case, and if yes, what values should be used?
