自定义服务UUID需要付费使用吗？

产品开发需要自定义一个服务，指定服务UUID时，是否与现有的不冲突就可以了？要不要通过SIG购买呢？

No one assigns 128-bit UUIDs. Wikipedia has a good overview of UUIDs (http://en.wikipedia.org/wiki/Universally_unique_identifier), and for most people type 4 (random) UUIDs are sufficient. To keep things simple we didn't use a truly random UUID, but rather created our base UUID using "0451" (TI's USB vendor ID) and made sure to follow the formatting of type 4 (random) UUIDs.

BT SIG allows you to buy 16-bit UUIDs and will probably have a program for 32-bit UUIDs; otherwise for anything else 128-bit UUIDs should be used.

不需购买

那么最好是用自定义的128位UUID，对吗？

是的

多谢Viki Shi。已经把UUID都改为128位的了。还想问个问题，如果产品中包含了自定义服务，是不是不需要去SIG做测试和质量鉴定，就可以在市场上销售呢？
