Hi, this week I spent a good part of my time looking for (and
testing) software in the following areas: |
- free Class Diagram generators
- BLE support in Android emulators
- ".so" libraries decompilers (targeted to ARM architectures).
This activity made it possible to integrate the guide with examples/ideas and alternatives to proprietary software (according to what proposed by my mentor). 
About the reverse engineering of the BLE scale: I managed to decompile the proprietary library "libyohealth.so" both in ARM assembly (using objdump and an ARM toolchain) and in C code (using RetDec decompiler) , but for obvious reasons it's not simple to understand its content.
