Subscribe Download PDF Cause scanner to beep. I have an application where I am connecting one laptop to up to 3 WWS800 or WWS850 Bluetooth scanners. Is there a command sequence I can send out the com port to cause the scanner to beep. Internal User 2017-04-10 in WWS800/850 The WWS 800 & WWS 850 is not a 2 way interface. The only way the scanner will beep is when it reads a good barcode. There is no way to send a command to the scanner to force it to beep.
