What does “Error while uploading. Try again later” mean when trying to upload the fingerprints?

The Error message “Error while uploading. Try again later” is shown by the Accuware Indoors App when your data connection (e.g. Wi-Fi or cellular) is lost and your device is not able to upload to the Accuware server the last set of fingerprint collected. We suggest to check to have a reliable data connection throughout the entire area before collecting the fingerprints or to upload the fingerprints when a data connection is available. Anyway when an upload fails, the Accuware Indoors App saves the last set of fingerprints collected allowing thus an upload in a later stage.
