https://devzone.nordicsemi.com/f/nordic-q-a/91213/ble-signal-spikesHello all the BLE module with the nRF52820 is programmed with a ble_app_uart_pca100e example from the nRF5SDK ver 17.1.0, according to the RSSI graph it seems it works , however, how to explain the spikes in the signal?

If you move either the TX or the RX or something in between that the signals reflects off, the properties will change and you will get a different RSSI level.</p><div style="clear:both;"></div>
