The U Grok It development tools

U Grok It is has an open development system and we encourage developers to build solutions on U Grok It or extend their current solutions to smartphones on our platform. We provide a number of developer tools/sdks, developer apps and end user apps.

Developer tools / SDKs

The Developer Tools are our SDKs that allow you to write native apps for iOS or Android. This gives you the most control over your end user’s experience. We have focused on making the U Grok It SDKs easy to use with high-level APIs that abstract the RFID functionality so you do not need any RFID expertise to integrate U Grok It into your app. To get started integrating U Grok It into your native app, download the U Grok It SDKs:

iOS, Android, Windows, Cordova, Xamarin

Latest version:

Native apps can be written to run without WiFi or Cellular connectivity.

Developer apps

U Grok It writes and publishes apps to help developers quickly provide basic connectivity to U Grok It and get their users gathering data from the Grokker. Developer apps provide a subset of U Grok It functionality in connection with your own browser-based app and server.


Send Grok for iOS

Send Grok for iOS is a simple app that scans tags and sends their tag info to a backend: an HTTP destination (URL), or an email address. As a developer you can control the app from a browser-based app: you can launch Send Grok from your app, use it to scan tags, and then return to your browser-based app. Developers can also have users run Send Grok without connecting it to a browser-based app. To do this, developers will need to provide end users with specific connectivity information to your web server. Send Grok is a complete app available in the app store, not source code, so developers cannot modify Send Grok or its UI.

Send Grok offers the power of allowing you to quickly get going on U Grok It without having to write a native app.

Because it’s a simple app that only sends tag information, Send Grok has some limitations:

  • It can only do tag inventories, it does not have a locate function.
  • It only displays and sends EPC numbers, not any associated database data.
  • It has to be connected to the backend via cell or wireless connectivity.
  • It cannot commission (write) tags.
  • As the developer you have no control over the UI within Send Grok.
  • Small user time overhead for going from the browser app to Send Grok and back.

Grok Keyboard for Android

With this Android soft-keyboard and an attached U Grok It RFID reader, it is possible to scan and enter RFID tag EPCs with arbitrary apps. A special key on this keyboard starts the RFID scanning system, and scanned EPCs are automatically entered into the current text field of a target app. To the app, the EPC appears as if it were entered manually. Modifications of the target app are not required for this purpose.

The Grok Keyboard provides an alternative input method for Android devices. Manual input is still supported.

Once installed and enabled the input method is available for all apps on your handset or tablet. The keyboard can be used with conventional apps, with browsers and with remote desktop applications (RDP).

The keyboard currently supports English.

It's a real time-saver: The app provides convenient RFID-scanning capabilities, typing efforts are reduced, and app-switching or copy/paste operations are eliminated completely.

End user apps

Discover Grok is our end user app to allow users and developers to explore the Grokker and its functionality.

Discover Grok 2 for iOS

The Discover Grok app for iOS with the U Grok It reader (the Grokker) turns your iPhone, iPod Touch or iPad into a UHF RFID reader that can identify, locate, track and inventory tagged items, scanning them within a 6’-25’ (2-7m) range, with the ability to read all the tags in that area.

Features:

  • Identify – Identify individual items in your database.
  • Count – Inventory and count all items in your database, or a subset of your database.
  • Locate – Find any specific item that is in your database.
  • Basic RFID – List the EPC code of tagged items as they are scanned.
  • Tag – Commission a UHF RFID tag and enter the item into your database or associate a name, data and picture with any already commissioned tag.
  • Data – Manage your database, add, remove and change fields.
  • Settings – Check battery level of the Grokker, create new databases and check version information.
  • U Grok It cloud – Register with U Grok It and synchronize your data across multiple iOS devices.
  • CSV import/export – Work with your existing data.

Grok Demo for Android

Grok Demo is a test app to use with the U Grok It Smartphone RFID system to bring the benefits of UHF Gen 2 RFID to your Android mobile device. The Grok Demo app showcases the full function features of the Grokker - including reading and writing tags, viewing EPC numbers and scanning local database items.

The Grokker is a key element of the U Grok It platform, which turns your smartphone into a UHF Gen 2 RFID reader that can locate and inventory tagged items, scanning them within a 6’-25’ (2-7m) in ideal conditions, and with the ability to read all the tags in that area.

U Grok It makes UHF Gen 2 RFID accessible and affordable, opening the technology to provide solutions to a wider target market including small and medium businesses.
