From 2ca7f3a4a03db3e7d7fa15504fa3d69e1c6bd217 Mon Sep 17 00:00:00 2001 From: José Bollo Date: Tue, 31 Oct 2017 10:50:24 +0100 Subject: Split in two: agl-identity-service and uds-ble-id-init-service MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The binding is splitted in two parts and packeged as widgets. The two parts are: - uds-ble-id-init-service This service provides a UDS (User Data Service) over BLE. It detects writes to the email of the user to initiate the authentication process. - agl-identity-service This service queries the Forgerock's Edge Controller to fill user data and make it available. The actual code is not fully functionnal.
