Abstract
A wireless power system may have a wireless power transmitting device and a wireless power receiving device. The wireless power transmitting device may include a coil and wireless power transmitting circuitry coupled to the coil. The wireless power receiving device may include a coil that is configured to receive wireless power signals from the wireless power transmitting device and rectifier circuitry that is configured to convert the wireless power signals to direct current power. The wireless power transmitting device and the wireless power receiving device may exchange data packets using in-band communication in order to transfer various types of data. For increased flexibility of data transmission, multiple data streams may be used concurrently when conveying data between the power receiving device and power transmitting device. Each data packet may include a stream header that identifies a corresponding data stream. Different types of data may be transmitted with each data stream.
