ESP8266 LMIC receive pakets

I’m using the arduino-lmic-master with an esp8266. The node do not receive data packets. Sending to the TTN ist ok.
I think reveiving should be in this part:
case EV_TXCOMPLETE:
Serial.println(F(“EV_TXCOMPLETE (includes waiting for RX windows)”));
if (LMIC.txrxFlags & TXRX_ACK)
Serial.println(F(“Received ack”));
Serial.print("EV_TXCOMPLETE, time: ");
Serial.println(millis() / 1000);
if (LMIC.dataLen) {
Serial.println(F(“Received “));
Serial.println(LMIC.dataLen);
Serial.println(F(” bytes of payload”));
}

But nothing happens. I made the gateway with the software from :slight_smile:https://github.com/ttn-zh/ic880a-gateway/wiki

On the ic880a board only the power led is on.

Thanks
