Subject: Unable to Parse Billing Profile Data (1.0.98.1.0.255) – Show Trace vs. Normal Output

Hi Team,

I'm currently able to read data from the meter using the billing profile object 1.0.98.1.0.255. However, I’m having difficulty parsing the actual values from the response.

With "Show Trace" enabled, I receive raw frame data like:

This confirms that data is being received, but it’s in raw frame format, which is hard to interpret directly.

Without "Show Trace", I get the following output:

1.0.98.1.0.255
Ch. 0 Data of billing period Scheme 1 #1 Unspecified number of most recent billing periods
------------------------------------------------------------------
1.0.98.1.0.255
------------------------------------------------------------------
[Ljava.lang.Object;@1f38510
------------------------------------------------------------------
[gurux.dlms.GXSimpleEntry@19ab809, gurux.dlms.GXSimpleEntry@2e94a0e, ...]
Instead of the actual billing values like B1, B2, timestamps, or readings, I’m only getting references to GXSimpleEntry objects.

My Questions:
How can I extract or decode the actual values from these GXSimpleEntry objects?

Is there a method or utility in the Gurux library to convert them into readable format (e.g., timestamps, kWh values)?

What’s the best way to loop through and access individual fields like bi, timestamp, etc.?
