摘要: Devices of a Bluetooth wireless communication system are adapted to include an L2CAP extension layer that calculates error control data for each packet of payload data. An error control data packet is transmitted immediately following each packet of payload data. The L2CAP extension layer checks incoming payload data packets using the associated error control data, to determine transmission errors such as caused by radio-frequency interference. A preferred example uses 32-bit Ethernet to generate an error control checksum, providing robust error checking for a high integrity transmission link such as between a computing device and a printer.
