A method includes, at a transmitter, performing a test of communications with a receiver, the test comprising: (i) sending, by a communications component of the transmitter, a first message to the receiver, (ii) receiving, by the communications component, a second message from the receiver in response to the first message, and (iii) comparing operational metric(s) associated with the first and second messages with respective expected values for each of the operational metric(s) to determine an outcome for the test. The method further includes sending a report to a remote server that includes the determined outcome for the test, and after sending the report, stopping performance of the test and starting normal operation of the transmitter in which the transmitter transmits, by at least some of the transmitter's antennas, power waves to a location of the receiver. The receiver uses energy from the power waves to charge/power an electronic device.
