...und Code zum Einstieg hab ich auch schon mal generieren lassen:

#include <drivers/gpio.h>

#include <string.h>

LOG_MODULE_REGISTER(LOG_MODULE_NAME);

// LoRaWAN network settings
#define DEV_EUI "123456789ABCDEF1"

#define APP_KEY "123456789ABCDEF3456789ABCDEF1234"

void main(void)
{
    int ret;
    const struct device *lora_dev;
    struct lora_modem_config config;

    // Initialize LoRaWAN stack
    lora_dev = device_get_binding(DT_LABEL(DT_INST(0, semtech_sx1276)));
    if (!lora_dev) {
        LOG_ERR("Failed to find LoRa device");
        return;
    }

    memset(&config, 0, sizeof(config));
    config.frequency = 868100000;
    config.bandwidth = LORA_BW_125_KHZ;
    config.datarate = LORA_SF10;
    config.coding_rate = LORA_CR_4_5;
    config.tx_power = 14;
    config.tx_timeout = 1000;

    ret = lora_start(lora_dev, &config);
    if (ret < 0) {
        LOG_ERR("Failed to start LoRa device (%d)", ret);
        return;
    }

    // Join LoRaWAN network
    ret = lora_join(lora_dev, DEV_EUI, APP_EUI, APP_KEY);
    if (ret < 0) {
        LOG_ERR("Failed to join LoRaWAN network (%d)", ret);
        return;
    }

    LOG_INF("Joined LoRaWAN network");

    // Send LoRaWAN message
    const char *msg = "Hello, world!";
    size_t msg_len = strlen(msg);
    ret = lora_send(lora_dev, msg, msg_len);
    if (ret < 0) {
        LOG_ERR("Failed to send LoRaWAN message (%d)", ret);
        return;
    }

    LOG_INF("Sent LoRaWAN message: %s", log_strdup(msg));
}

This code initializes the LoRaWAN stack, configures the network settings, joins the LoRaWAN network, and sends a message over the network. You can customize the LoRaWAN network settings to match your specific application requirements. Note that this code assumes that you have set up the Zephyr RTOS development environment and have the necessary libraries and drivers installed.
