我尝试在 LoRaWAN 中设置一个终端节点。我使用 ST Microelectronics 的板 b_l072z_lrwan1 和 Zephyr OS。我在 VSCode 上使用 PlatformIO。

我使用 GitHub 上的代码https://github.com/fcgdam/zLorawan_Node。

这是我在网关上看到的（所有 EUI 都将被更改）：

对我来说，这意味着网关收到了一个好的请求。这是我在 ZephyrOS 上的配置。

#define LORAWAN_DEV_EUI         { 0x3D, 0x74, 0x04, 0xD0, 0x7E, 0xD5, 0xB3, 0x70 }    // LSB Format!
#define LORAWAN_JOIN_EUI        { 0x11, 0x11, 0x11, 0x11, 0x22, 0x22, 0x22, 0x22 } 
#define LORAWAN_APP_KEY         { 0x33, 0xE6, 0xF7, 0xF7, 0x5B, 0x46, 0xD2, 0xDC, 0x7F, 0xC4, 0x7C, 0x5F, 0x94, 0x56, 0x06, 0x43 }

我的请求因 errno -116 超时，即 ETIMEOUT

这是我在 TTN 中的设备配置： 我的设备说明

你知道为什么我的请求超时吗？

我已经在 LSB 中编写了 DEV_EUI 但是，TTN 似乎在 MSB 中得到了它，当我颠倒字节的顺序时它就起作用了。
