ESP32 + RFM95C を The Things Network に接続しようとしています。
私が受け取ったエラーは単純です: 24951: EV_JOINING 24970: EV_TXSTART 426696: EV_JOIN_TXCOMPLETE: no JoinAccept
そしてそれは繰り返されます、これが私のセットアップコードです:
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.

私の接続がうまくいかない理由を誰か知っていますか?
