What is LoRaWAN Codec
This tool decodes and encodes LoRaWAN packets and estimates airtime, useful for gateway debugging, protocol learning, and link optimization.
Key Features
- Decode core LoRaWAN frame fields.
- Build basic uplink/downlink packets by MType.
- Convert across multiple input/output formats.
- Estimate airtime and effective data rate.
Steps
- Input packet data in Decode tab and choose format.
- Inspect MHDR, MACPayload, and MIC fields.
- Fill parameters in Encode tab to generate packets.
- Use Airtime tab to evaluate timing and throughput.
FAQ
Why is decode output incomplete?
Payload may be truncated, format may be wrong, or encrypted fields require extra context.
Why does airtime differ from real measurements?
Verify SF, bandwidth, coding rate, and preamble settings against actual regional/device configuration.
