Subject: Connecting to Bluetooth Low Energy devices
Date: Thu, 13 Sep 2012 17:34:38 +0200 [thread overview]
Message-ID: <67399724.T38U7nJAul@arawn> (raw)
Hello
Trying to get started with Bluetooth Low Energy devices, i used hcitool and
gatttool to enumerate device attributes, but did not get far:
# hcitool lescan
LE Scan ...
<MAC-Device1> Battery V1.0
<MAC-Device1> (unknown)
<MAC-Device2> Battery V1.0
<MAC-Device2> (unknown)
^C
# gatttool -b <MAC-Device1> -I
[ ][<MAC-Device1>][LE]> connect
Connecting... connect error: connect error: Connection refused (111)
[ ][<MAC-Device1>][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)?
Regards
Philipp Claves
