+#### LoRa® Receiver Example
+
+This example listens for packets and prints them to the Serial Monitor. It uses a simple polling method where the main loop waits until a packet is received. Upload this code to a second Nesso N1 to receive messages from the transmitter.

+```arduino
+#include <RadioLib.h>
+
+// Initialize the radio module, passing RADIOLIB_NC for the reset pin.
+SX1262 radio = new Module(LORA_CS, LORA_IRQ, RADIOLIB_NC, LORA_BUSY);

+void loop() {
+  // Check if a packet is available.

+

+    // Packet was received successfully.
+    Serial.print(F("[SX1262] Received packet: "));
+    Serial.println(str);
+
+    // Print packet statistics.
+    Serial.print(F("[SX1262] RSSI: "));
+    Serial.print(radio.getRSSI());
+    Serial.print(F(" dBm, SNR: "));
+    Serial.print(radio.getSNR());
+    Serial.println(F(" dB"));
+
+  } else if (state == RADIOLIB_ERR_CRC_MISMATCH) {
+    Serial.println(F("[SX1262] CRC error!"));
+  } else if (state != RADIOLIB_ERR_RX_TIMEOUT) {
+    // Some other error occurred. Timeout is expected and ignored.
+    Serial.print(F("[SX1262] Failed, code "));

+  }
+}
+```
+
+***Please note: because the `LORA_ENABLE` pin is on an I/O expander, it cannot be passed directly to the RadioLib library constructor. The library must be initialized with the reset pin set to `RADIOLIB_NC` and is best practice to perform a manual reset in setup.***
