Hello,
I increased the MAX TX field of the UA response frame from 71bytes to 230 bytes, during SNRM frame negotiation.
However, when I request the object list, I get a response "GetObjects failed. Invalid count". See frame below,

I check all the necessary length fields, and I can not figure out where why I got such a response.
Kindly advice!

Hi,
Hi,
Your GBT data is wrong. That is causing the problem. Check the bytes before the array data.

Hello Mikko,
Hello Mikko,
Thanks once again for your reply.
I actually figured that out and fixed it when I saw the block length was more than 128, so it should be 2 bytes.
Thanks once again.
