Hi, I am following the next tutorial :

hhttps://learn.sparkfun.com/tutorials/esp32-lora-1-ch-gateway-lorawan-and-the-things-network?_ga=2.50826346.2118500240.1550669780-1924351644.1507658708#routing-to-the-things-network and I can't even upload the sketch.

After a few trials, I change the arduino ide board option from "SparkX ESP32 LoRa Gateway" to "Esp 32 Dev Moule" and the upload speed from 921600 to 115200 and I finaly could upload the sketch.

But when I acces to tthe Serial Monitor, the log it shows repeteadly is:

Rebooting...

Why is there a warning after lora1272 is initialized
uint8_t version = readRegister(REG_VERSION); // Read the LoRa chip version id
if (version == 0x22) {
// sx1272
#if DUSB>=2
Serial.println(F("WARNING:: SX1272 detected"));
#endif
sx1272 = true;
}

else if (version == 0x12) {
    // sx1276?

#if DUSB>=2
if (debug >=1)
Serial.println(F("SX1276 starting"));
#endif
sx1272 = false;
}
