Configuring a zebra scanner via spp

I'm writing an android app, that scans barcodes with a zebra rs6000 scanner connected via bluetooth (spp). So far is everything OK, it works.

Now I'm wondering if it's possible to send feedback to the user like different beep-sounds and/or LED colors on the scanner (whether or not the process behind the barcode was successfull).

I know it's possible to configure the scanner beforehand to make different beeps and show different colors scanning "configuration-barcodes", but I need to change these settings from my app. Has anyone an idea?

Any help would be very appreciated!
