Step 3: Downloading
When the OPR3301 is connected and Appload has been correctly configured you can
now start the download procedure by reading the label below.
Enter download mode
As a result of this the OPR3301 should start blinking the green LED and the following
message should appear on your screen.
Now open the software file that you want to download on the OPR3301 using:
File > Transfer > Transmit NetO file.
The downloading of the software should now start. Underneath the screen a progress
bar will be shown to indicate the progress of the software downloading.
The loading of a new application generally will take less than a minute. Loading a new
Operating System can take between 3 and 10 minutes depending on the file type (bin-
files are faster than hex-files) and the quality of the Bluetooth connection.
When the downloading is complete, Appload will show a message on the screen that
the uploading was successful. *
If the received files are found to be ok, then the OPR3301 will start installing the
software. This can take up to 15 seconds to complete.
In case the OPR3301 detects that the uploaded file is not compatible it will sound a low
error beep and no software will be installed.
If the installation was successful the OPR3301 will reset and will sound the start-up
buzzer.
* Note: No message will be shown on the screen that indicates whether the software
was installed successfully or not, because the Bluetooth connection is closed before
the installation starts. Listen to the response of the OPR3301 instead.
