Ok,
Thank you for your answers, that’s really help me

I use the EU868 channel plan.

At start, I tried on 1.4.1 and then I passed on the 1.4.3 and I saw the same problem.

Yes, in fact all those command frames are on the port 0:
{ “ack”: true, “adr”: true, “appeui”: “fe-dc-ba-98-76-54-32-10”, “chan”: 4, “cls”: 0, “codr”: “4/5”, “datr”: “SF12BW125”, “deveui”: “00-00-00-00-00-20-03-9c”, “freq”: “867.3”, “lsnr”: “7.8”, “mhdr”: “409c032000a00100”, “modu”: “LORA”, “opts”: “”, “port”: 0, “rfch”: 1, “rssi”: -67, “seqn”: 1, “size”: 4, “timestamp”: “2018-01-09T14:49:33.925661Z”, “tmst”: 567051324, “payload”: [ 7, 3 ], “eui”: “00-00-00-00-00-20-03-9c”, “_msgid”: “ab4abc30.54b54” }

The ACK frame too:
{ “ack”: true, “adr”: true, “appeui”: “fe-dc-ba-98-76-54-32-10”, “chan”: 1, “cls”: 0, “codr”: “4/5”, “data”: “”, “datr”: “SF12BW125”, “deveui”: “00-00-00-00-00-20-03-9c”, “freq”: “868.3”, “lsnr”: “8.5”, “mhdr”: “409c032000a00200”, “modu”: “LORA”, “opts”: “”, “port”: 0, “rfch”: 0, “rssi”: -65, “seqn”: 2, “size”: 0, “timestamp”: “2018-01-09T14:49:38.657740Z”, “tmst”: 571780068, “eui”: “00-00-00-00-00-20-03-9c”, “_msgid”: “a4620411.5b9df8” }

My application receive and transmit packets in node-red with lora input/output nodes.

So, it seems that the command answers are bring to node-red application.
