LORAWan doesn't work with custom parameters

Hi,

I have a Lora 32 (v3). I can upload demos and all is ok.
The example “lorawan_oled.ino” join with default devEui, appEui, AppKey and do something. But I don’t have the results on “https://lora.heltec.org”. And it’s ok.

I change the program with custom devEui, appEui and appKey and compile/upload the program.

uint8_t devEui[] = { 0x96, 0x59, 0x8C, 0xEB, 0x70, 0xEC, 0xF9, 0x8F }; /* 96598ceb70ecf98f */

uint8_t appEui[] = { 0x5A, 0x91, 0x7C, 0x7B, 0x4D, 0x39, 0x75, 0x5F }; /* 5A917C7B4D39755F */

uint8_t appKey[] = { 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xXX }; /* XXXXXXXXXXXXXXXXXXXXXXXXXXXXX */

I setup “lora.heltec.org” with following :

I launch the ESP and it starts but I have this in loop :

01:33:49.556 -> RX on freq 869525000 Hz at DR 0
01:33:49.775 -> Event : Rx Timeout
01:33:50.460 -> TX on freq 868100000 Hz at DR 5
01:33:50.538 -> Event : Tx Done
01:33:55.512 -> RX on freq 868100000 Hz at DR 5
01:33:55.558 -> Event : Rx Timeout
01:33:56.573 -> RX on freq 869525000 Hz at DR 0
01:33:56.731 -> Event : Rx Timeout
01:33:57.462 -> TX on freq 868500000 Hz at DR 5
01:33:57.546 -> Event : Tx Done

Can someone can help me ?
