1. A method of configuring a wireless power transmitter using a communications test, the method comprising:

  • detecting, by a wireless power transmitter that includes a plurality of antenna elements configured to transmit power waves, a wireless power receiver within a communication range of the wireless power transmitter;

    in response to detecting the wireless power receiver within the communication range of the wireless power transmitter, performing a communications test over a predetermined period of time that tests communications between the wireless power transmitter and the wireless power receiver;

    after expiration of the predetermined period of time, determining whether the communications test has passed;

    in accordance with determining that the communications test has passed, transmitting by at least some of the plurality of antennas of the wireless power transmitter power waves that converge to form a constructive interference pattern in proximity to a location of the wireless power receiver, wherein the wireless power receiver uses energy from the constructive interference pattern to charge or power an electronic device that is coupled with the wireless power receiver; and

    in accordance with determining that the communications test has not passed, sending a report regarding the communications test to a remote server.
