https://devzone.nordicsemi.com/f/nordic-q-a/27405/modify-service-characteristic-uuidI am working on blinky example and want to modify service/characteristic uuid. I do that in ble_lbs.h as follows: //#define LBS_UUID_SERVICE 0x1523 #define LBS_UUID_SERVICE 0x1526 //#define LBS_UUID_BUTTON_CHAR 0x1524 #define LBS_UUID_BUTTON_CHARen-USTelligent Community 13Tue, 21 Nov 2017 02:09:06 GMThttps://devzone.nordicsemi.com/thread/108223?ContentTypeID=1Tue, 21 Nov 2017 02:09:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1cd38c92-0d18-424d-b289-88538fc5aaafMax<p>I run my example this morning and surprisingly saw the modified uuids. My guess is that the LightBlue (on iPhone) somehow saves contexts locally and displays un-updated uuid. Anyway, I consider this case solved.</p><div style="clear:both;"></div>
