Esp32 LoRa lmi c TTN не подключается

Question

Я пытаюсь подключить свой ESP32 + RFM95 C к The Things Network.

Я получаю простую ошибку: 24951: EV_JOINING 24970: EV_TXSTART 426696: EV_JOIN_TXCOMPLETE: no JoinAccept

И это повторяется. Вот мой установочный код:

static const u1_t PROGMEM APPEUI[8]= { secret stuff here };

void os_getArtEui (u1_t* buf) { memcpy_P(buf, APPEUI, 8);}

// This should also be in little endian format, see above.
// static const u1_t PROGMEM DEVEUI[8]= { secret stuff here };
static const u1_t PROGMEM DEVEUI[8]= { secret stuff here };
void os_getDevEui (u1_t* buf) { memcpy_P(buf, DEVEUI, 8);}

// This key should be in big endian format (or, since it is not really a
// number but a block of memory, endianness does not really apply). In
// practice, a key taken from ttnctl can be copied as-is.
static const u1_t PROGMEM APPKEY[16] = { secret stuff here };
void os_getDevKey (u1_t* buf) {  memcpy_P(buf, APPKEY, 16);}

static uint8_t mydata[] = "Hello, world!";
static osjob_t sendjob;

// Schedule TX every this many seconds (might become longer due to duty
// cycle limitations).
const unsigned TX_INTERVAL = 60;

Ничего особенного, просто шаблонный скетч-код.

У меня есть шлюз LoRaWan Dragino LPS8 со следующими настройками:

Кто-нибудь знает, почему мое соединение go не проходит?
