Method for detecting and resolving data corruption in a UART based communication network

摘要

A method for communicating information between networked UARTs to achieve reliable peer to peer communication. A negative acknowledgement (NACK) signal is generated in the event that message corruption is detected by a node on the network to flag the message corruption and generates a signal which is guaranteed to corrupt the message in progress by overwriting the stop bit of the UART character frame. This causes all receivers of the message in progress to cancel reception of a corrupted message and causes transmitters to retry transmission of the message. The invention does not impose any limits on the number of nodes on the network and does not require any special data content other than a unique source address that is assigned to each node on the network.
