HOW TO USE SNAPLINX
SnapLinx must be manually started when your device is rebooted. Please ensure that Bluetooth is turned on before starting SnapLinx. Your device must have an active connection to the Internet (WiFi, cell data, etc.) to send and receive notifications, files and links through SnapLinx. In some instances, such as when SnapLinx has not been used for a while, SnapLinx must be brought to the foreground to receive notifications.
Android 8+ devices may require that battery optimization be turned off for SnapLinx to receive notifications when SnapLinx is in the background and when the screen is turned off. Even with battery optimization for SnapLinx turned off, Android 9 devices may not receive notifications when the screen is turned off. To turn off battery optimization for Android 8+ at the expense of slightly higher battery consumption, a variant of the following should work:
Settings → Apps or Apps & notifications → SnapLinx → Battery → Optimize battery usage or Battery optimization → All or All Apps (from top drop-down list) → SnapLinx → Off (toggle) or Don't optimize (popup)
Note: the current Android version of SnapLinx available on the Play Store supports reception of files and links only (sending of files or links is not supported). In addition, the current Android version only receives notifications when SnapLinx is in the foreground and on the Receive screen. We will update the Android version of SnapLinx in the near future to support sending files and links to nearby iOS and Android smartphones.
To share a file or link, open or select the file or link in an app or browser. Note that some apps and browsers may not work well with SnapLinx, and sharing a file or link may cause an error to be displayed. If this happens, please try a different app or browser.
Next, click the share button or icon on your Android or iOS device, and select SnapLinx. In iOS, confirm that you want to share the file or link in the popup dialog box and wait for the file or link to upload to the server.
Note that not all file types are supported by Android and iOS. PNG, JPG, GIF, MP4, MP3, WAV, DOC(X), XLS(X), PPT(X) and PDF (all fonts embedded) files should work for both Android and iOS. For DOC(X), XLS(X) and PPT(X) files, compatible viewers are recommended for Android (e.g.: Google Docs, Google Sheets, Google Slides). Some file browsers may not support the sharing of some common file types; in this case please try a different browser.
Next, open the SnapLinx App (Snaplinx should open automatically on Android devices after an upload to the server), go to the Send screen, and click on the new item. Edit the Notification Label and Notification Text fields as necessary and click “Send” on iOS, Save and Send in the menu for the item on Android. The default Notification Label and Notification Text may also be used.
SnapLinx will transmit SnapLinx BLE Advertisements for three minutes, which may be scanned by nearby devices with SnapLinx installed and used to retrieve and display a notification of the shared file or link from the server. SnapLinx must remain in the foreground or SnapLinx BLE Advertisements may cease. The random Bluetooth MAC Address of the SnapLinx BLE Advertisement may be changed by Android during the three minute transmission window, and some Android devices may stop transmitting. If you find that smartphones with SnapLinx installed are not getting any notifications cancel and then resend the transmission.
In most cases, clicking on a notification on a receiving device will download and open the file or link in a viewer. The viewer may allow users to store the file or link in local device storage. On Android devices, a file may in some instances download but not open automatically; the user may open Chrome, select Downloads from the menu, or open a file browser and select Downloads, and open the file manually.
Users will have 12 hours to download and view a file or link before automatic deletion on the server. The file or link may also be manually deleted by the sender. The file size limit is 2 MB, and up to four files or links may be stored on the server at a time by each user. When sharing photos from your smartphone, please use a resolution that provides photos smaller than 2 MB.
Dismissed SnapLinx system notifications may be viewed on the Receive screen on the SnapLinx App.
1. On Android, a file may occasionally be duplicated on the server when sharing. If this occurs, please delete any duplicated files from the Send screen.
2. On some Android phones, the transmitting screen may not appear immediately when sending a file or link. If this occurs, please try the following:
a. Quit all apps,
b. Disable Bluetooth from the Status/Notification bar,
c. From Settings → Apps or Apps & notifications → See all <n> apps or All Apps → Show System from menu → Bluetooth or Bluetooth Share → Storage → Clear Cache and Clear Data,
d. Enable Bluetooth from the Status/Notification bar and restart SnapLinx.
