BLE : UUID service (128bits) and UUID characteristic with a slight differencehttps://devzone.nordicsemi.com/f/nordic-q-a/66208/ble-uuid-service-128bits-and-uuid-characteristic-with-a-slight-differenceHi based on nus example , I&#39;d like to create RX/TX characteristics with a custom UUID (128bits) My problem is about the UUID characteristics versus UUID service, for example my UUID service is like this UUID service : 5ABB-1234-5614_..... anden-USTelligent Community 13Tue, 22 Sep 2020 13:56:41 GMTRE: BLE : UUID service (128bits) and UUID characteristic with a slight differencehttps://devzone.nordicsemi.com/thread/270880?ContentTypeID=1Tue, 22 Sep 2020 13:56:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7ff1c68a-2aa7-4359-a13d-e8e39ff6ea70Will_008700<p>it works, thanks</p><div style="clear:both;"></div>RE: BLE : UUID service (128bits) and UUID characteristic with a slight differencehttps://devzone.nordicsemi.com/thread/270803?ContentTypeID=1Tue, 22 Sep 2020 11:06:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a4f9bbba-4931-44ca-97c7-21f151e9920eVidar Berg<p>Yes, this is the correct way to solve it.
