Solution of the "Challenge 1" (Nordic tutorial)

[TheRaven]

Hello,

I used this tutorial : devzone.nordicsemi.com/.../

But I can't resolve the "Challenge 1" (write 4 bytes on the characteristic). Can you explain me, please ? :-)

Thanks a lot !

I recommend doing the tutorial with the example files provided, or else at least this challenge doesn't make sense, because challenge 1 and 2 shouldn't be a problem while you get trouble with challenge 3.

What is len? Is it 4?

Also you have to change the max length (attr_char_value.max_len) of the button characteristic value.

Yes of course ! ;-)
