Okay, finally it’s working. For all readers of this topic who have the same Problem:

The [WiF LoRa 32(V2)](http://www.heltec.cn/project/wifi-lora-32/?lang=en) has **another** pin-mapping. The user [saglettn](https://www.thethingsnetwork.org/forum/u/saglettn) faced the same issue and posted a comment into this topic: [Big ESP32 + SX127x topic part 3](https://www.thethingsnetwork.org/forum/t/big-esp32-sx127x-topic-part-3/18436/31).  
If you used the pin-mapping from this post: [Big ESP32 + SX127x topic part 2](https://www.thethingsnetwork.org/forum/t/big-esp32-sx127x-topic-part-2/11973) and you are using [WiF LoRa 32(V2)](http://www.heltec.cn/project/wifi-lora-32/?lang=en) you have to change the pin-mapping to:

```
// Pin mapping
const lmic_pinmap lmic_pins = {
    .nss = 18,
    .rxtx = LMIC_UNUSED_PIN,
    .rst = 14,
    .dio = {26, 34, 35},
};

```

I did not found this in a topic. It seems that the **V1** Version of the Heltec LoRa 32 is using `.dio = {26, 33, 32}`.
