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:

ComponentDescription
TypeIndicates the frame type (CRC, RX, TX, APRSIS_TX)
Raw FrameThe unprocessed APRS frame data
RSSIReceived Signal Strength Indicator in dB
SNRSignal-to-Noise Ratio in dB
FREQ ERRORFrequency 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

Example Frames

For RX and CRC Frames

RX,-105,8.5,250,SQ2CPA-10>APRS,WIDE1-1,WIDE2-1:!5302.20N/01829.80E>000/000/A=000123 LoRa APRS Tracker

For TX and APRSIS_TX Frames

TX,SQ2CPA-10>APRS,WIDE1-1,WIDE2-1:!5302.20N/01829.80E>000/000/A=000123 LoRa APRS Tracker
