Is there a way to change LoRaWan DevEui ?
DevEui is automatically generated by the LoRaWan stack.
Two questions :
- How is it generated from the Unique_Id ?
- Is there a way to change it (overload) by script ?
@bmarkus the idea is , as supposed by @jmarcelino , to make easier the field replacement of defective devices without loosing history (the application software is not easy to patch to take care of this kind of change).
It would be convenient, for example to replace a device in the field without much intervention at the backend or losing the history.
Another option I'm exploring is getting a EUI64 block for our own projects (App EUIs etc) and it would be nice to have everything in the same range.
From what I can tell the EUI is "burned" into the secure flash region and read at runtime by config_set_lpwan_mac()
Just curious, why do you want to change DEVEUI?
