Hello Sollae I have a question about when i debug return data between host -> cse-H53n has been cut 1200byte each block! Example: Send request to host get data thought CSE-H53n ①size of file download is 3Mb. Request: Device ---> CSE-H53n ---> Host(①) Response: 1. Device(receive 1200byte) <--- CSE-H53n(receive 1200byte) <--- Host(send 1200byte) 2. Device(receive 1200byte) <--- CSE-H53n(receive 1200byte) <--- Host(send 1200byte) 3. Device(receive 600byte) <--- CSE-H53n(receive 600byte) <--- Host(send 600byte) Data receive from host to cse-H53n is cut 1200 byte for each block. 1200 byte is default value? Can i change it?
