Send and Receive examples with AES128 encryption

[EliasA97]

I was trying to communicate with encryption, but I wasn't able to do it and spent many days finding a solution. As I found out how to do it, I'm posting here for anyone else looking the same thing.

SX126x_encrypted.zip

The sketces are modified library examples. These are for SX126x Lora devices, but you can make it work for every module the library supports.

Also you can get the AES library from here: https://github.com/DavyLandman/AESLib

Hope it helps!
