Flow Firmware Update v1.031 - Android

Enhancements included in this update, allow you to pause and restart your sessions and also reduces time to generate recommendations.

Please follow these steps closely, using your mobile phone

1. Download 'nRF Toolbox for BLE' (by Nordic Semiconductor ASA) from the Play Store

This is the app that sends the firmware update to your SMB Flow over Bluetooth.

2. Click on the 'Download the Firmware Update Zip File' button here using your phone

Go to this page on your phone and download the file.  The file should now be in your ‘downloads’.

3. Open nRF Toolbox

Select the “DFU” option

4. Click on 'SELECT FILE'

Click the SELECT FILE button.

5. Leave option as 'Distribution packet (ZIP) and click 'OK'

In the dialog box that opens, leave the selection on the Distribution packet (ZIP) and click OK.

6. Choose the SMBV1.031.zip file

You are now shown all the files in your directory.  Navigate to ‘Downloads’ and select the SMB Zip file.  Note that on some Android phones, this is done by long pressing the file then clicking on ‘open’.

If your phone simply shows you the files inside the zip, then it’s likely you’ll need to long press.

Note: Image above shows old update file.  Yours should say SMBV1.031.zip

In the dialog “Select Scope”, leave it at the default of “All” and click OK.  You are returned to the main screen which now shows the SMBV1.031.zip file as the  ”APPLICATION” file selected.
