Learn how to use the LoRa APRS Analytics Platform and understand frame formats
Important: Currently, only SQ2CPA software available at flasher.lora-aprs.pl supports this solution. The platform is specifically designed to work with this software's frame format and processing capabilities.
Frame Format
The LoRa APRS Analytics Platform processes frames in a specific format. Each frame consists of several components:
| Component | Description |
|---|---|
| Type | Indicates the frame type (CRC, RX, TX, APRSIS_TX) |
| Raw Frame | The unprocessed APRS frame data |
| RSSI | Received Signal Strength Indicator in dB |
| SNR | Signal-to-Noise Ratio in dB |
| FREQ ERROR | Frequency error in Hz |
Frame Types
- CRC: Frame with CRC validation
- RX: Received frame
- TX: Transmitted frame
- APRSIS_TX: Frame transmitted over TCP/IP to APRS-IS
