How do I re-enable the scanner if nothing was scanned using EMDK 5?

How do I re-enable the scanner if nothing was scanned using EMDK 5? J Jon-Luke West 3 years 6 months ago 24 1 0 I am working on an application for the MC92KK using EMDK v5.0. I have followed the samples and have gotten scanning to work, as long as I actually scan something. If I do not scan anything, the scanner turns off and will no longer respond to the hard trigger press. I am assuming this is because the scanner.read() method in the onData() call back is not being fired; thus never initializing the scanner again. How do I overcome this so that the hard trigger turns the scanner on regardless of whether data was captured or not? Thank you.

Hi Jon,

In the samples they refer to that as 'continuous scanning' mode.  In code they're just re-submitting the read whenever the scanner enters the idle state, see here: samples-emdkforandroid-5_0/MainActivity.java at BarcodeSample1 · Zebra/samples-emdkforandroid-5_0 · GitHub where they call the scanner.read() method from onStatus() rather than onData().
