while I was trying to test my app on Pebble Emulator using Pebble SDK 3.0, I met a connection problem. The Emulator is working normally, but my host machine can't connect to QEMU virtual machine. So, the app wasn't fired up. See followings:
> pebble build
> pebble --debug install --emulator aplite
[INFO ] Starting phone simulator...
[ERROR ] Could not connect to phone at localhost:12342. Ensure that 'Developer Connection' is enabled in the Pebble app.
