+# A-GPS Data
+
+Load assisted GPS data directly to the watch using the new http requests on Android GadgetBridge.
+
+Make sure:
+* your GadgetBridge version supports http requests
+* turn on internet access in GadgetBridge settings
+
+The widget loads the data in the background every 12 hours. It retries every 10min if the http request fails. It is only visible during a request or on error.
