I got a bit forward with the JS version as I can see clearly from the $FFFD values it must be some kind of UTF8 issue. Still I left the original function as-is (but disabled) as it might be useful.
Note that I don't like to add another component (Webviewer) for this conversion but I thought I'd try with a different method, too.
In the meantime I commented out the "asc" procedure I copied from the Internet (thanks to the kind person who originally created it) and replaced with a Webviewer component and now I use Javascript to convert characters to their ascii code. It downloads an example Arduino binary file from my site. OK, I created a strip-down version of my project.
#0XED BINARY HOW TO#
Can anyone point me how to download a binary file to memory and use its content as a byte stream? I figured maybe the method I'm using to download assumes plain text file but I have to download the file and send its content to the microcontroller as-is. I also see that the length of the variable does not match with the file size on the server. The downloaded content is not the same that the content on the server. If the user clicks on the "update" button, I go through the content of the global variable, convert the characters to byte and send them one by one via the Bluetooth serial.I save the contents to a global variable.That's why I used the GotText() method instead of the GotFile() method. I don't want to save the file to the phone's file system because it contains sensitive data. Download a binary file using the Web component.I have no issues with the Bluetooth communication. I'm working on a method to download and send data from Android phone to a microcontroller connected via Bluetooth serial.
