Other Parts Discussed in Thread: BLE-STACK
I would like to use the BEM (instead of BIM) for over-the-air download of encrypted firmware, because we have clients who want to protect their firmware from running on other similar products.
However the OAD Guide PDF only talks about the BIM. I can see references to the BEM in the source code, and also found the BEM IAR project (which has linker issues that I have to fix). Is this a supported feature? I also found linker scripts for generating encrypted firmware Image-A and Image-B, but the post-build command seems to be the same as non-encrypted version, so where does the encryption of the image occur? I also found a Bootloader-Encrypter.exe tool in the BLE-STACK, but it seems to require a serial port (??).
Basically, where can I find more documentation about encrypted OAD? :-)
