Gurux sends "Object reference not set to an instance of an object" in the pass 4 of the HighGMAC authentication

Forums
Gurux.DLMS

Hello,

I want to establish Aplication Association between Gurux and a Meter using the HLS GMAC mechanism.

When the communication is in the "pass 4: Response to challenge: f (CtoS)", I get the message: "Object reference not set to an instance of an object".

Send AARQ request.

Unable to read profile generic object of meter ER300P using method ReadRowsByRange().

Forums
Gurux.DLMS

Hi Mikko,

I am trying to read DLMS/COSEM compatible ER300P meter using Gurux C++.

I am able to read register and data objects properly but not able to read profile generics objects.
I am reading profile generic object "1.0.99.1.0.255" (15 Minutes) by method ReadRowsByRange() but I am unable to read it. It some times returns Error "Device reports Read-Write denied" and some times
"Invalid parameter".

Understanding GuruxDLMS.c Arduino Client Sketch

Forums
Gurux.DLMS

Hello,

I am trying to implement a automatic meter reader using arduino on an ESP32. I need to understand how the client sketch here https://github.com/Gurux/GuruxDLMS.c/tree/master/Arduino_IDE can be used.

1. Is the Serial declared with baud 9600 expected to be connected to an optical device or is it the host system running Arduino IDE?

2. How are the read values stored?

3. Can you provide a link to some documentation on this?

Thank you
