The LoRaSniffer App is the user-interface for the LoRaSniffer Device. The combination of both, the device and the app, is a tool for technicians and hobbyist allowing to use LoRa radio communications for testing and network maintenance. The LoRaSniffer Device is a LoRa radio module that can use all possible features the LoRa standard offers. This app is its convenient user-interface. It connects via BLE to the device to allow access to all its setup-parameters, receive communications from other LoRa nodes and send data via LoRa. Using 2 coupled LoRaSniffer devices, it can provide valuable information about network quality in a real-world scenario. The app provides a logging window with features for: formatting of received communications, additional time-stamp and the GPS location where each message was received. Each received message is tagged with "Quality of Signal" information as CRC, SNR, RSSI and carrier-frequency offset. The app allows as well to save the logged data as a visual document in HTML or as JSON protocol file. Messages can be sent as ASCII-text or as binary data. Tools allow to scan for channel activity, calculate transmission times for specific payloads or, if used with 2 devices, allow to gain real-time information to optimize LoRa networks in the field. More, the app can be used as well to update the firmware of the LoRaSniffer device.
