More Information
Summary:Two devices containing NFC radios may use some of the NFC components to permit one device to wirelessly charge a battery in the other device. Time sharing between the communication and charging, functions may allow the two devices to use the same frequency for both functions, without the charging, function causing interference in the communication function. One device may periodically transmit polls, with both a data exchange communication period and a charging period occurring between two successive polls. In some embodiments, a data exchange period using the NFC radios and a charging period using the charging circuitry do not overlap in time.
