Hi,

I have a question on SZX in the Block2 Option.

Does the payload bytes of the response packet MUST be exactly same as the SZX chosen in Block2 Option or Can it differ with that of SZX?

For example, I send a Block which is NOT the last block and I choose SZX = 2 (i.e., Block size is 64 bytes). But the actual payload in the response is 75 bytes or 57 bytes not 64 bytes. Is this valid?

Thanks!
