@crispyoz hello, indeed, I start to be oriented, but the way will be long. I'll write all this. My project also involves a lot of other things to validate.
I know now that it is possible.
As I understand it, there is still for each Onion a configuration to do. The main interest is that there is a possible update after IOTs are deployed?
I will dig your tracks, thank you again. Jean Marc

@crispyoz Hello, thank you for your answer. It is possible. However, I have no experience with package repositories and bootloader changes after first wifi connection.
Do you have any information, tutorials or information in this area?
thanks for advances
