SX1272-Communication

These two Arduino sketches were used to measure electromagnetic attacks impacts against the LoRa (phy) protocol.

LoRa Modulation parameters used during these measures

These parameters provide a better sensibility.

• Spreading Factor (SF): 12

• Bandwidth (BW): 125 kHz

• Coding Rate (CR): 4/5

• Center Frequency (FC): 868.3 MHz

• Explicit Header: Enabled

• Preamble Length: 12

• Payload Size: 9

Transmitter

Broadcasts, every 2155ms a new frame (LoRa packet) over the air.

Receiver

Receives and prints the last packet's RSSI and the global RSSI for every received packet.
