Method measure

examples/WebSocketServer/MeasureRSSI.cpp:33–62

* If the real-time measurement is required, the MeasreRSSI::measure function * should always be called within the loop function. A sketch does not have to * intentionally create a measurement period. In particular, don't use delay. * It just adds unnecessary delays. * @return true The measurement is completed. MeasureRSSI::rssi has the * average value of RSSI measured for the specified numb

 * @return  false Measurement in progress.
