Conteúdo dados
Protocol:o TEXT_MESSAGE_APP
Tamanho: 196 bytes
Decoded: Sim
Comteúdo da SMS:
The sx1262's "listen before talk" (LBT) feature is a communication protocol that checks for channel activity before transmitting data. If the channel is busy, the module will wait and retry later.

MQTT Privacy & Exposure Analysis

Analysis of privacy features and exposure risks when packet is shared via MQTT

Exposure Level: Broadcast
Privacy Features:
  • ✓ Direct LoRa transmission (not via MQTT)
  • ✓ Gateway node ID tracked
Exposure Risks:
  • ⚠ Visible to all nodes on channel
  • ⚠ Default channel - no encryption
  • ⚠ Packet visible to MQTT subscribers
  • ⚠ Multi-hop path visible (2 hops)
  • ⚠ RF signal metrics exposed (location inference possible)
