Managing device power on sequences and communications control for wireless power transfer

An apparatus for controlling wireless charging communications, the apparatus comprising:

• a wireless power receiver circuit configured to wirelessly receive power from a wireless power transmitter;
• and
• a transceiver circuit operatively connected to the wireless power receiver circuit, the transceiver circuit configured to wirelessly transmit and receive data, the transceiver circuit comprising a transceiver controller and a transceiver memory, the transceiver memory configured to store a set of instructions defining a wireless power communication profile for managing a wireless power charging session between the wireless power receiver circuit and the wireless power transmitter, the transceiver controller configured to execute the set of instructions to cause the transceiver circuit to wirelessly transmit and receive data according to the wireless power communication profile,
• the wireless power receiver circuit configured to provide power to the transceiver circuit in response to receiving power, the wireless power receiver circuit further configured to, in response to receiving power, provide a power source signal to the transceiver circuit indicating that the power provided to the transceiver circuit is from the wireless power receiver circuit,
• the transceiver controller configured to, in response to receiving the power source signal, execute an initialization sequence, wherein as at least a part of the initialization sequence the transceiver controller is configured to:
• transmit an advertisement message to the wireless power transmitter according to the wireless power communication profile for establishing a wireless communication session with the wireless power transmitter;
• and
• initialize one or more other functions defined by the wireless power communication profile after transmitting the advertisement message.
