I am just implementing the Error-Handling of my device. HCF_Spec-81 says under 5.4 that the Framing of the message must be aborted if an error is detected within Byte Count. Now i wonder what kind of error that could be. Since it is only one byte, it is not possible to have to many bytes and if the number is to small the error would occur in the data field and not in the Byte Count.
What shall happen if i get an incomplete request? Should i ignore it, or is that also depending on the field i received last?
