Battery V1.0 (unknown) Battery V1.0 (unknown) ^C # gatttool -b -I [ ][][LE]> connect Connecting... connect error: connect error: Connection refused (111) [ ][][LE]> This is all i get. The devices are Nordic Semiconductor nRF8001 based and currently run a simple BTLE demo application by Nordic Semiconductor. It does not use bind/paring but simple connect. Unfornately that doesn't seem to work. The host uses an of-the-shelf USB Bluetooth 4.0 Stick with a Broadcom BCM20702A0 Chip inside. Am i doing something obviously wrong? Any tips where to get more information about the error (dmesg shows nothing)?
