The property endpoint.framework.uuid is used in the remote service admin, I
think the property you are looking for is FRAMEWORK_UUID
(org.osgi.framework.uuid). Apache Celix does not support this yet. I will
try to add this in the coming days.

In the meantime if you just need a unique id, you could also generate one
with apr_utils. The endpoint.framework.uuid is generated in same way:

celix_status_t remoteServicesUtils_getUUID(apr_pool_t *pool, BUNDLE_CONTEXT
context, char **uuidStr) {
        celix_status_t status =3D CELIX_SUCCESS;

        status =3D bundleContext_getProperty(context,
ENDPOINT_FRAMEWORK_UUID, uuidStr);
        if (status =3D=3D CELIX_SUCCESS) {
                if (*uuidStr =3D=3D NULL) {
                        *uuidStr =3D apr_palloc(pool,
APR_UUID_FORMATTED_LENGTH + 1);
                        if (!*uuidStr) {
                                status =3D CELIX_ENOMEM;
                        } else {
                                apr_uuid_t uuid;
                                apr_uuid_get(&uuid);
                                apr_uuid_format(*uuidStr, &uuid);
                                setenv(ENDPOINT_FRAMEWORK_UUID, *uuidStr,
1);
                        }
                }
        }

        return status;
}


I hope this helps.

Greetings,
Pepijn
