How to protect Lopy application code from being read by hacker.

[Divyank Saxena]

I am developing a communication device based on lora.
If a hacker got my device then, I don't want that he can read my application code.

Is there any way to encrypt my application or lock the ROM in lopy4.
Any solution will be appreciated.
Thanks

Yes you can freeze the code https://docs.pycom.io/advance/frozen/ -we are doing it but be aware that it is rather tricky, and my experience from the GPy is that all devices does not really like it. If you are prepared for the work, then this is your best option.
