Lora Sniffer 1.0.2

The LoRaSniffer App serves as the primary user interface for the LoRaSniffer Device, forming a comprehensive toolkit for technicians and enthusiasts engaged in testing and maintaining LoRa radio networks. When used in conjunction with the device, the application facilitates detailed monitoring and control of LoRa communications.

The LoRaSniffer Device itself is a versatile LoRa radio module capable of utilizing all features offered by the LoRa standard. The app provides seamless connectivity via Bluetooth Low Energy (BLE), granting access to extensive device settings, real-time reception of data from other LoRa nodes, and the ability to transmit data via LoRa. Notably, when employed with two interconnected devices, the system can gather valuable insights into network quality under real-world conditions.

The application includes a comprehensive logging interface equipped with functionalities such as message formatting, timestamping, and GPS location tagging for each received message. Signal quality metrics—including CRC, SNR, RSSI, and carrier-frequency offset—are annotated for every communication. Users can export logged data as visual HTML documents or as JSON protocol files for further analysis.

Messages may be transmitted as ASCII text or binary data, with additional tools to scan channel activity and calculate transmission durations for specific payloads. When using two devices, the app enables real-time network optimization by providing immediate feedback on network performance.

Furthermore, the app supports firmware updates for the LoRaSniffer Device, ensuring that users can maintain and enhance device functionality through straightforward software upgrades.
