Multiple lamps #10

Hi,

First of thanks for the effort, it was rather huge surprise to see this rather exotic product get implemented to home automation.

But I have rather strange issue. I have two bedside lamps and it seem the yeelight_bt server can connect only to one of them in rather random order. I've been able to reproduce same issue in cli as well. Please find attached logs:

This is a known problem when trying to connect on multiple btle devices concurrently, but I'm unsure on what part of the stack the problem lies (chipset? bluez? bluepy?). Unfortunately there is no easy fix for it at the moment.

Considering there's nothing this library can do to alleviate the problem, I'm closing this for now.
