This can be done by going to Main Window > Tools > Firmware Updater. Also, try to update the application that you have on your mobile devices. After you did this, lunch the application on your device, and from the computer application, right click on Group GUI and select Upload Group to HAI Application. By doing this, the Group that you recently made will be transfered to the mobile application. For additional support, download the user manual from the following website.
