Tab in the LoRa Scanner sweeps 863-870 MHz in 100 kHz steps (the strongest of three RSSI readings at each, at 125 kHz), shown as bars with peak hold over a waterfall, the Sniffer's frequency marked (Q98). The Sweep pauses the Sniffer and keeps its packets; Tab resumes it (Q99). Status Bar: SW. The floor, top and peaks are host-tested; `lora sweep on|off|dump` prints them on the console. At the desk: about 607 ms a pass, a flat floor at -100 to -102 dBm (15 dB above the chip's own) and a steady carrier at 863.2 MHz.
