# RSL FOTA iOS Limitations

Note the following important details when using the RSL FOTA iOS® Mobile Application:

| • | The RSL FOTA Mobile Application for iOS requires the Bluetooth Low Energy feature to be enabled to scan for Bluetooth Low Energy devices.

| • | The easiest way to add a new FOTA file to the RSL FOTA Mobile Application is to send an email to the device with the file attached. After downloading the file from the email, press the File icon once more, and a popup is displayed where the user can select which app to use to open the file. Select the RSL FOTA Mobile Application. The file is then imported to the application, and is visible when the user presses the Select File button on the Update Firmware screen.
