[SailfishDevel] LED Flash functionality on a real Jolla

[christopher.lamb at thurweb.ch]

Hi Mohammed

thanks. I will try that later (am at work at the moment). I will also  
need to look into the resource policy engine, as that is new to me.

Harbour entry is becoming less and less of a concern for me. My app  
does too many things that are not considered kosher under the current  
Harbour rules (sending SMS direct, use of QtContacts, LED access,  
other Qt Libraries etc.)

As an aside, on Harmattan while I got the the Gstreamer route working  
in developer mode, I never got it working when launching the app  
direct from the device (and thus chose the QCamera approach). This was  
probably down to AEGIS, but that should not be a concern on the Jolla.

Chris
