My OTAA node can not be connected

Hi,
Since along time, I need to reactivate some OTAA station.
I have been create a new Application and I registered an new OTAA devise name st43 (LMIC 5.0.1 ).

To register my new devise I almost copy the devise st9 which has been created in 2022. I can not test the devise st9 because I do not have it physicaly.

I can not understand why my devise st43 can not be seen by TTN.

I edited the devise st43 and here are the settings:

Let say, that the AppEUI is with all zero
Let say that the DevEUI end with 43 43 43

I guest, the problem my come from now


While I create the new devise, I observed the latest LoRaWAN version is 1.1.0 but I kept as I did some year ago. Is may a problem?

Regarding the Join Setting, I leaft all empty excepted for the AppKey

Now, in my Arduino script, I reported the value as the following


/ This EUI must be in little-endian format,
  static const u1_t PROGMEM APPEUI[8] = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };  
  // This should also be in little endian format, see above.
  static const u1_t PROGMEM DEVEUI[8] = { 0x43, 0x43, 0x43, 0x00, 0x00, 0x00, 0x00, 0x00 };
  // This key should be in big endian format (or, since it is not really a
  static const u1_t PROGMEM APPKEY[16] = { 0x??, 0x??, 0x??, 0x??, 0x??, 0x??, 0x??, 0x??, 0x7F, 0xD0, 0x3E, 0x3B, 0x??, 0x??, 0x??, 0x?? };

I read that “The JoinEUI (formerly call AppEUI)”.

I wonder if during the last year some udate have been make and I have to register my devise in a different way. For example, should I better use

I am a bit confuse, as all my 40 devises has been well working, but it was in 2022 :slight_smile:

I just would like to add.
At my place, I have two gateway and one of them is a TTIG. I simultaneity connect the fisrt and the the TTIG and both are seen in my console. Then I do not think it’s a gateway issue
