Samsung refrigerator UART bus reverse engineering demo

Demonstration of decoding raw data from a Samsung refrigerator over the UART link between the WiFi board and main board. It runs at 9600 baud 8N1. Nothing too bespoke here (see what I did there). It is a standard protocol used on all their appliances and fairly simple to decode. There isn't even a CRC. It's a basic XOR checksum. submitted by /u/doitaljosh [link] [comments]
