Abstract:
1. A method comprising: wirelessly transmitting an encoded message from a peripheral device to a host system, the encoded message comprising first reconciliation data, wherein the first reconciliation data is a multi-bit cyclic redundancy check (CRC) data; wirelessly receiving at the peripheral device an acknowledgement message from the host system, the acknowledgement message in response to the encoded message and including second reconciliation data, wherein the second reconciliation data is a multi-bit cyclic redundancy check (CRC) data; determining at the peripheral device whether the host system has information to transmit to the peripheral device through determining whether the second reconciliation data of the acknowledgement message received at the peripheral device is the first reconciliation data modified in a predetermined way, wherein the first reconciliation data modified in the predetermined way includes the first reconciliation data modified through an inversion operation; and determining a mode of the peripheral device based on the determination of whether the host has information to transmit to the peripheral device.
