motivated by the usefull link in ltomuta's signature, I wanted to give on device debuggin a try. I went through the steps but because I debug a Qt application, my .mmp file has some more entries than the one shown in the video. I can build my application just fine and can install it using nokia software installer but I get an error about an expired certificate when trying to debug on the device. I get the same warning even when I uncheck "Do not show installer on phone" on the phonescreen then.
The device is a 5800 XM but I think the error is not related to the bug mentioned elsewhere about some software but because installing using nokia software installer works just fine.
I saw that in the video, the vendor id was commented out before on device debugging. I do not have such a line in my project but two other lines regarding UIDs:
UID 0x100039CE 0xE635F0EC
I want to use self signed certificate for now.
