Wireless power systems with concurrently active data streams

An electronic device that is configured to receive wireless power from a power transmitting device, the electronic device comprising:

• a coil that is configured to receive wireless power signals from the power transmitting device;
• rectifier circuitry that is configured to convert the wireless power signals to direct current power;
• and
• control circuitry configured to convey data packets using the coil, wherein each of the data packets has a stream header that identifies a corresponding data stream associated with that data packet.

A wireless power transmitting device with a charging surface configured to receive at least one wireless power receiving device, the wireless power transmitting device comprising:

• a coil;
• wireless power transmitting circuitry coupled to the coil and configured to transmit wireless power signals with the coil;
• and
• control circuitry configured to:
• transmit a first data packet for a first data stream to the wireless power receiving device using the coil;
• and
• while the first data stream is active, transmit a second data packet for a second data stream to the wireless power receiving device using the coil.
