Hi Warren,

The error code 0x1E is “Integrity Error” and means that the CRC or the MAC does not match to the data or the padding bytes are not valid.

For deeper analysis it is difficult or impossible to make a statement when you do not know what the unknown framework does.

Please have also a look to this post:

Here I have checked the ChangeKey command with a tool.
