Hallo Forum,
ich nutze die Arduino IDE 2.04 .
Mein Kit Dragino Single Channel LoRa IoT Kit v2 .
Das Kit enthält den Arduino Uno.

Den folgenden Sketch möchte ich einsetzen:

* This example sends a valid LoRaWAN packet with payload "Hello,
* world!", using frequency and encryption settings matching those of
* the The Things Network.
*
* This uses ABP (Activation-by-personalisation), where a DevAddr and
* Session keys are preconfigured (unlike OTAA, where a DevEUI and
* application key is configured, while the DevAddr and session keys are
* assigned/generated in the over-the-air-activation procedure).
*
* Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in
* g1, 0.1% in g2), but not the TTN fair usage policy (which is probably
* violated by this sketch when left running for longer)!
*
* To use this sketch, first register your application and device with
* the things network, to set or generate a DevAddr, NwkSKey and
* AppSKey. Each device should have their own unique values for these
* fields.
*
* Do not forget to define the radio type correctly in config.h.

Wie stelle ich die von The Think Network v3 entnommen Keys in die erforderliche Arduino Sketch Form um? Siehe dazu Bild "Seite 34" oder PDF File.
Ist mein Anliegen verständlich oder fehlen weitere Informatioen?

EKLAERUNGEN
ABP – Activation by Personalization
ABP ist die Art und Weise, wie ein Endgerät zu einem bestimmten LoRa-Netzwerk gehören kann, ohne unter bestimmten Bedingungen einen Join-Vorgang durchzuführen. Im ABP-Modus verfügt das Endgerät nicht über DevEUI, AppEUI und AppKey, die für das Join-Verfahren unerlässlich sind. Die Aktivierung eines Endgeräts durch Personalisierung bedeutet, dass der DevAddr und die zwei Sitzungsschlüssel Nwk_SKey und App_SKey direkt im Endgerät gespeichert werden, anstatt während des Join-Vorgangs von DevEUI, AppEUI, AppKey und NwkKey abgeleitet zu werden.
