FPV Scanner pairs with the FPV Scanner Module over Bluetooth® to scan the 5.8 GHz FPV spectrum. Choose your FPV equipment (DJI, Walksnail, HDZero, Analog, etc) and watch real time scanning of 5.8 Ghz frequencies, with your channels overlaid. Advanced analytics tell you if a channel is triggered by FPV equipment, so you can see which channels are being used (with historical timeline), and which are open. Label channels with pilot names so you know what your friends are using. Optionally have your device notify you as channels are triggered and available. The module keeps track of the history data, so you can turn on and off the phone or app and still see the last 10 minutes of activity. Key features - Real-time 5.8 GHz scan with per-channel RSSI bars - 10 minute channel history to catch brief activity spikes - Channel activity alerts (optional notifications) - Module management with quick reconnect - OTA firmware updates via your Wi-Fi credentials Requirements - FPV.Scanner.Module hardware: bit.ly/FPVScanner - Bluetooth® enabled on your iPhone/iPad
