First of all, URL https://developer.motorolasolutions.com/community/technologies/advanced… stopped working,
but URL on emails do .
Second, I received (at last!) the unit and I started testing my templates.
So...
First thing I found is that xmls must be on \sdcard\templates folder so app is aware of them, despite documentation says:
 
Copy the template to the /sdcard/template folder or the /enterprise/device/settings/dpx/templates folder so the software can detect it.
 
Once selected, I tried, but... I was bloody not able to decode the simplest one (actually a real case), which I attach for someone else to try and see what I did wrong. I suspect I might have to raise to 3 MP the size, but I am not sure.
Problem is that it remains forever saying to stay steady...
