Bluetooth PAN serving a Phoenix app

First of all, thank you for your answer.

I just tried this afternoon on Raspbian and I was able to setup a working PAN.
For dmesg, there is no error.

I like to have ambitious projects when I try out a technology. It allows me to really try to understand how it works, especially when I’m trying to do something and there is little documentation on the topic ^^

I will try again and I will update this post if I manage to get the NAP working on Nerves.
