Nikon P900 issue

[joem65]

Are not able to download pictures/movies from my Coolpix P900 camera.

When the download should start, I get this message:
——————-

Does not matter if I select images in the camera or on your computer.

what could be the problem?

Thanks. This might be the same issue as the J5. I’m still trying to get a hold of a J5 – it should only take a day or two to resolve once I have one. To help me see if it’s the same issue can you set the logging level to ‘debug’ and retry the download and post the resulting log here? Thanks!

Of course. Here it is:

I think you’ve done an awesome program. Good luck!!

Thanks for posting the debug log. It appears to be the same issue with the J5. I’m still trying to get a hold of one…

Any news ab. the Coolpix P900 ? Still cannot do the wifi to Mac. . . .

[Adam]

The J5 and P900 issue has been resolved. The fix will be included in the v1.1 release, which is expected in about a week or so.
