Gurux DLMS for Java

I have successfully established the Bluetooth connection and completed both the SNRM and AARQ stages. However, during the Association View phase, I'm facing an issue where the full HDLC response is not being received consistently. Despite requesting the maximum MTU size of 517, the response often gets truncated.

For example, sometimes the Association View responses complete up to the 9th continuation request, while at other times, it stops at the 3rd or 4th request, resulting in an incomplete frame and a parsing failure.

Hi, Try to add a small delay…

Hi,

Try to add a small delay between frames. Have you tried to decrease the MTU size?

BR,
Mikko
