Hello everyone,

My goal is simple : 1 - On my first laptop, i'm using bleno 2 - On my second laptop, i'm using nativescript-bluetooth v2.0.0-beta.23 3 - When my second laptop read the service from my second laptop -> get a string

How can i do that ? First, time to explain a bit what i did so far ! :)

First laptop: I created a project with bleno

On my second laptop (i'm using VMWare with Ubuntu) i try to get the service from my first laptop. Big problem : The services are empty...

{ UUID: '74:29:AF:80:17:BA', JS: name: 'echo', JS: state: 'connected', JS: services: [ [length]: 0 ]}
