Subject: tools: Add setting Value property of gatt-service
X-Git-Tag: android-x86-4.4-r3~4541
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=4987c5bc20cf1ef1e77c015f6b607f04f40ee5ae;p=android-x86%2Fexternal-bluetooth-bluez.git

tools: Add setting Value property of gatt-service

This patch extends the gatt-service.c example adding a generic callback
to allow set the characteristic Value. It doesn't check for
characteristic properties yet.
