Return-Path: From: Jukka Rissanen To: linux-bluetooth@vger.kernel.org Subject: [PATCH v2 7/8] Bluetooth: 6LoWPAN: Create a kernel module Date: Fri, 23 May 2014 12:27:27 +0300 Message-Id: <1400837248-12179-8-git-send-email-jukka.rissanen@linux.intel.com> In-Reply-To: <1400837248-12179-1-git-send-email-jukka.rissanen@linux.intel.com> References: <1400837248-12179-1-git-send-email-jukka.rissanen@linux.intel.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Instead of adding the 6LoWPAN functionality to Bluetooth module, we create a separate kernel module for it. Usage: In the client side do this: # modprobe bluetooth_6lowpan # echo 'psm 62' > /sys/kernel/debug/bluetooth/hci0/6lowpan # hciconfig hci0 leadv In the server side do this: # modprobe bluetooth_6lowpan # echo 'psm 62' > /sys/kernel/debug/bluetooth/hci0/6lowpan # hcitool lecc E0:06:E6:B7:2A:73 # echo 'connect E0:06:E6:B7:2A:73 1' > \ /sys/kernel/debug/bluetooth/hci0/6lowpan The 6LoWPAN functionality can be controlled by psm value. If it is left to 0, then the module is disabled and all the 6LoWPAN connections are dropped if there were any. The 6lowpan controlling interface is a temporary solution until the specifications are ready.
