Error while execute DFU example in Mesh SDK

Hi Giang,
The issue is that the public key isn’t being converted to a bytearray properly.

Applying the following diff will solve the problem

Additionally, there was an issue where the device_page_generator.py would always output the same filename (device_page_nrf52832_xxAA_s132_6.0.0.hex). That is fixed with the following diff:

https://stackoverflow.com/questions/492387/indentationerror-unindent-does-not-match-any-outer-indentation-level

That is a python error. Check if your leading spaces/tabs are correct for the added lines.

Thank, You also encounter this error?

After I insert your code :

I get error :

  File "device_page_generator.py", line 69
    if not (isinstance(bl_info_type, BLInfoType) and
                                                   ^
IndentationError: unindent does not match any outer indentation level

Any suggest ? Thank

Check the beginning of my ticket here:
https://devzone.nordicsemi.com/f/nordic-q-a/34378/mesh-dfu-example-not-working-no-serial-communication-for-linux-and-more

This is how I fixed it.

"

- Using the device_page_generator.py the string for the public key was read as unicode so I had to add this part:

if(isinstance(data, unicode)):
data = data.encode('utf-8')

after line 65. So I got this running and could generate device pages. Even though I can not imagine that I am the only one having this problem O_o
